Product details
Overview
MAX9698BCPE from Maxim Integrated is a dual, very fast TTL-output comparator fabricated in a high-frequency bipolar process (fT = 6GHz), delivering 6ns propagation delay, ±5V supply operation, and complementary TTL-compatible outputs. It features differential inputs, latch-enable functionality per channel, and is specified for 0°C to +70°C operation in 16-pin plastic DIP packaging. It is used in high-speed threshold detection within ADC front-ends and line receivers.
For engineers reviewing the MAX9698BCPE datasheet, MAX9698BCPE pinout, MAX9698BCPE application, or MAX9698BCPE equivalent, key selection considerations include latch-enabled dual-comparator timing integrity, TTL-level output drive capability, ±5V dual-supply compatibility, and legacy military-grade availability alternatives.
Technical Context
The MAX9698BCPE implements two independent high-speed comparators with fully differential inputs and complementary TTL outputs, each with dedicated latch-enable (LE1/LE2) control. Its 6GHz fT bipolar process enables sub-10ns propagation delays while preserving DC matching (±3mV input offset voltage, 4µV/°C drift).
Latch operation is edge-triggered: when LE goes high, outputs capture and hold the input state at transition; unused LE pins must be grounded. The device requires ±5V supplies (absolute max ±6V), supports ±5V input common-mode range, and delivers 20mA output sink/source capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 6ns typical (input-to-output high), enabling >200MHz signal processing without timing violation. |
| Supply Voltage | ±5V (±6V absolute max), requiring dual-rail power design with decoupling near V+ and V− pins. |
| Input Offset Voltage | ±3mV max, ensuring accurate threshold comparison under DC-coupled conditions. |
| Latch Setup Time | 2ns, dictating minimum input stability window before LE rising edge for reliable latching. |
| Output Logic Compatibility | TTL-compatible: VOH ≥2.4V @ −3mA, VOL ≤0.5V @ 8mA, directly driving 74LS/74F loads. |
| Operating Temperature | 0°C to +70°C (Commercial grade), validated for stable performance across industrial ambient ranges. |
| Power Dissipation | 336mW max (at TA = +70°C), requiring thermal derating above ambient per θJA = 180°C/W (DIP). |
Pinout & Package
MAX9698BCPE is supplied in a 16-pin plastic DIP package (0.300" wide), with through-hole mounting and standard DIP footprint compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | GND | Ground reference for both comparators and latch logic; requires low-impedance connection to PCB ground plane. |
| 2, 15 | LE2 / LE1 | Latch-enable inputs - active-high; must be tied low if unused to prevent floating-state metastability. |
| 3, 14 | Q2 / Q1 | True (non-inverted) TTL outputs - drive high/low compatible with standard TTL logic families. |
| 4, 13 | Q2 / Q1 | Complementary (inverted) TTL outputs - provide differential output pair per comparator channel. |
| 5, 12 | −IN2 / −IN1 | Inverting inputs - accept differential or single-ended signals within ±5V common-mode range. |
| 6, 11 | +IN2 / +IN1 | Non-inverting inputs - referenced to GND; require matched layout for optimal high-speed rejection. |
| 7, 10 | V− / V+ | Negative and positive supply terminals - require local 0.1µF ceramic decoupling capacitors at each pin. |
Key Features
| Feature | Design Value |
|---|---|
| 6GHz fT bipolar process | Enables <10ns propagation delay while maintaining ±3mV input offset and 96dB CMRR - rare combination for high-speed analog decision circuits. |
| Dual independent latch-enable inputs | Allows asynchronous sampling of two separate analog signals with precise timing control, eliminating need for external latch ICs. |
| TTL-compatible complementary outputs | Provides direct interface to 74LS/74F logic without level-shifting or pull-up resistors, reducing BOM count and board area. |
| ±5V dual-supply operation | Supports symmetrical signal handling around ground, essential for bipolar analog front-ends in data acquisition and instrumentation. |
| Pin compatibility with LT1016/Am686 | Enables drop-in replacement in legacy designs using those comparators, preserving existing PCB layouts and test fixtures. |
Applications
| High-Speed ADC Front-End | Peak Detection Circuit |
|---|---|
Use Scenario: Sampling analog input prior to flash or pipeline ADC conversion at >100MSPS rates. IC Role / Device Role / Timing Role: Dual comparator acts as high-speed track-and-latch element, with LE inputs synchronized to ADC clock edges. Use Value: 6ns propagation delay ensures minimal aperture uncertainty; complementary outputs feed differential encoder logic directly. | Use Scenario: Capturing maximum amplitude of fast-rising pulses in radar or laser pulse detection systems. IC Role / Device Role / Timing Role: Comparator compares input against ramp or reference, with latch enabled at pulse peak via external timing circuit. Use Value: 2ns latch setup time allows precise peak capture; ±3mV offset minimizes amplitude measurement error. |
| High-Speed Line Receiver | Threshold Detector for Digital Eye Monitoring |
Use Scenario: Recovering NRZ data from lossy coaxial or twisted-pair transmission lines operating above 100Mbps. IC Role / Device Role / Timing Role: Dual comparator reconstructs logic levels from degraded analog waveforms, with one channel for data and one for clock recovery. Use Value: TTL-compatible outputs drive FPGA I/O banks directly; 20mA drive strength sustains signal integrity over short traces. | Use Scenario: Real-time eye diagram analysis in serial link validation, where crossing-point and jitter are measured. IC Role / Device Role / Timing Role: Comparator sweeps threshold voltage across eye opening while latched outputs record pass/fail decisions per sample. Use Value: Differential inputs reject common-mode noise on probing fixtures; latch function freezes decision state for digital capture. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9698CPE | Same die, identical electrical specs, same 16-pin plastic DIP package - only difference is commercial temperature grade (C vs B suffix denotes same spec bin). | No functional difference; MAX9698CPE is the standard commercial version, while MAX9698BCPE reflects a specific screening or traceability variant. | Select MAX9698CPE for new designs unless B-grade traceability or lot-specific documentation is contractually required. |
| LT1016CN | Slower (10ns propagation), lower supply current (12mA), no latch enable, 8-pin DIP - pinout and functionally distinct but historically used in similar high-speed comparator roles. | Lacks latch functionality and dual-channel integration; requires external latches and additional support components for equivalent functionality. | Use only where latch-free operation suffices and timing budget allows 4ns+ added delay; verify layout compatibility due to different pin assignment. |
Compared with MAX9698BCPE, MAX9698CPE offers identical performance with broader availability and full production support, while LT1016CN provides a legacy alternative lacking latch control and speed - making MAX9698CPE the preferred upgrade path for continuity, and LT1016CN a fallback only in non-latched, lower-speed contexts.

FAQ
What is the operating temperature range for MAX9698BCPE?
The MAX9698BCPE is rated for commercial temperature operation from 0°C to +70°C. This range is verified per Maxim's original datasheet Rev 2 (19-2399), and applies to all electrical specifications including propagation delay, input offset voltage, and latch timing parameters. The 'B' suffix does not indicate extended temperature grading - it reflects a specific manufacturing lot or traceability designation within the commercial grade. MAX9698BCPE is not rated for military or extended temperature use.
Does MAX9698BCPE have latch-enable functionality on both channels?
Yes, MAX9698BCPE provides independent latch-enable inputs (LE1 and LE2) for each of its two comparators. When LE1 or LE2 transitions high, the corresponding comparator's outputs capture and retain the input state at that instant. Outputs remain latched as long as the respective LE pin stays high. Unused LE pins must be tied to GND to prevent undefined behavior - this requirement is explicitly stated in the MAX9686/MAX9698 datasheet.
What power supply configuration is required for MAX9698BCPE?
MAX9698BCPE requires dual ±5V supplies (V+ = +5V, V− = −5V), with absolute maximum ratings of ±6V. The device draws up to 50mA from V+ and 40mA from V− under full-load conditions. Local 0.1µF ceramic decoupling capacitors are mandatory at both V+ and V− pins, placed as close as possible to the package. Ground connections (pins 1, 8, 9, 16) must tie to a low-impedance PCB ground plane to maintain high-speed stability.
Is MAX9698BCPE pin-compatible with other comparators in the same family?
MAX9698BCPE is pin-compatible with MAX9698CPE and MAX9698MJE (16-pin CERDIP military version) - all share identical pin functions and assignments. It is also documented as pin-compatible with LT1016 and Am686, though those are single comparators in 8-pin packages and thus require adapter layout or redesign. True drop-in replacement is only valid among 16-pin MAX9698 variants; cross-family compatibility requires verification of signal routing and supply configuration.
Why is MAX9698BCPE marked "Not Recommended for New Designs"?
MAX9698BCPE is marked "Not Recommended for New Designs" because its wafer fabrication process has been discontinued by Maxim's external foundry. While the part remains available for legacy support and obsolescence management, Maxim advises new designs to consider alternatives such as MAX9698CPE (same specs, active production) or newer-generation comparators like MAX9021. Technical support and full datasheet access remain available for existing users, but long-term supply continuity cannot be guaranteed.
