Product details
Overview
MAX900BCPP from Maxim Integrated is a quad high-speed voltage comparator with differential analog inputs and TTL-compatible outputs featuring independent latch inputs per channel. It delivers 8ns typical propagation delay at 5mV overdrive, consumes 18mW per comparator at +5V, and supports ±5V or single +5V analog supplies with input common-mode range extending to the negative rail. It is used in high-speed A/D converters and line receivers.
For engineers reviewing the MAX900BCPP datasheet, MAX900BCPP pinout, MAX900BCPP application, or MAX900BCPP equivalent, key selection considerations include latch-enabled output hold capability, dual-supply flexibility (VCC/VEE for analog, VDD for digital), guaranteed 10ns max propagation delay over full temperature range, and compatibility with TTL load interfaces requiring fan-out of four.
Technical Context
The MAX900BCPP implements four independent high-gain comparators with internal active pull-ups on TTL outputs and dedicated latch inputs (pins 4, 7, 14, 17) that freeze output states when driven low. Its analog input stage operates with common-mode voltage down to VEE − 0.1V, enabling ground-sensing operation in single-supply configurations where VEE = GND.
Timing behavior is characterized by matched tpd+ and tpd− response times (10ns max over full temperature range), <2ns inter-channel propagation skew (∆tpd), and latch-disable delays (tpd+(D)/tpd−(D)) under 12ns - all specified with 15pF load and 2mA output drive, supporting clean edge detection in sampling circuits and V/F converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 10ns max (tpd+, tpd−) at 5mV overdrive, 15pF load - ensures sub-100MHz timing resolution in sampling systems. |
| Power Dissipation | 18mW per comparator at +5V - enables dense quad-channel deployment without thermal derating in compact layouts. |
| Input Offset Voltage | 2mV typ / 6mV max over full temperature - supports accurate threshold detection in precision analog monitoring. |
| Supply Flexibility | VCC = +5V to +10V or ±5V; VDD = +5V only - allows single-supply (VCC=+5V, VEE=GND) or split-rail analog operation. |
| Output Drive | VOH = 2.4V min / VOL = 0.4V max at 1mA source / 8mA sink - directly interfaces standard LS-TTL logic without external pull-ups. |
| Latch Input Threshold | VLH = 1.4–2.0V, VLL = 0.8–1.4V - compatible with standard TTL logic levels for synchronous capture control. |
Pinout & Package
MAX900BCPP is housed in a 20-pin plastic DIP package (0°C to +70°C operating range), with through-hole mounting and 0.3-inch body width. Pin functions are validated per Maxim's official pin configuration diagram for MAX900.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10, 11, 20 | IN− (A, B, C, D) | Negative input terminals for each of four independent comparators - referenced to VEE for differential sensing. |
| 2, 9, 12, 19 | IN+ (A, B, C, D) | Positive input terminals - support common-mode range from VEE − 0.1V to VCC − 2.25V. |
| 3 | GND | Ground reference for latch and digital circuitry - separate from analog substrate (VEE). |
| 4, 7, 14, 17 | LATCH (A, B, C, D) | TTL-compatible enable inputs - driving low holds current output state; no effect on MAX901. |
| 5, 6, 15, 16 | OUT (A, B, C, D) | TTL-output stages with internal pull-ups - drive LS-TTL loads directly with fan-out of four. |
| 8 | VEE | Negative analog supply and substrate connection - must be tied to system analog ground or −5V rail. |
| 13 | VDD | +5V digital supply - powers latch logic and output buffers; not adjustable. |
| 18 | VCC | Positive analog supply - configurable from +5V to +10V, defining upper input common-mode limit. |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent latched comparators | Four channels with dedicated latch inputs enable synchronized sampling across multiple analog signals without external logic. |
| Single-supply ground-sensing input | Input common-mode includes VEE (down to GND when VEE = GND), eliminating level-shifting in 0–5V sensor interface designs. |
| Matched propagation delay | ∆tpd ≤ 2ns between any two outputs ensures consistent timing alignment critical for multi-channel A/D front-ends. |
| TTL-compatible output drive | VOH ≥ 2.4V and VOL ≤ 0.4V at rated load meet LS-TTL VIH/VIL specs - removes need for external pull-up resistors. |
| Low-power high-speed operation | 18mW per comparator at +5V achieves 8ns speed with minimal thermal impact in space-constrained PCBs. |
Applications
| High-Speed A/D Converters | Line Receivers |
|---|---|
Use Scenario: Sampling analog waveforms at >50MHz using flash or pipeline ADC architectures. IC Role / Device Role / Timing Role: Quad comparator array acts as parallel threshold detector feeding encoder logic; latch inputs synchronize decision capture to clock edge. Use Value: 10ns max propagation delay and <2ns inter-channel skew ensure precise time-aligned digitization across all bits. | Use Scenario: Recovering digital data from noisy, attenuated transmission lines (e.g., RS-422, long-haul UART). IC Role / Device Role / Timing Role: High-speed comparator converts differential line voltage into clean TTL-level logic; latch holds last valid state during signal dropout. Use Value: Input range including negative rail allows direct interfacing to bipolar line signals without AC coupling or bias networks. |
| Threshold Detectors | PWM Circuits |
Use Scenario: Monitoring multiple sensor outputs (e.g., temperature, pressure) against programmable alarm thresholds. IC Role / Device Role / Timing Role: Each comparator compares one sensor voltage to DAC-generated reference; latches hold alarm status until serviced. Use Value: Independent latch per channel enables asynchronous event capture across eight inputs (using two MAX900s) without CPU polling overhead. | Use Scenario: Generating precise duty-cycle-controlled gate drives for motor control or SMPS feedback loops. IC Role / Device Role / Timing Role: Comparator compares sawtooth ramp to control voltage; latch freezes PWM edge timing against noise-induced jitter. Use Value: 8ns typical delay and TTL output drive allow direct connection to logic-based gate drivers with minimal added latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9202BCPP | Pin-for-pin compatible; same 8ns typ delay but 9mW/comparator (half power); no latch inputs. | Requires external latch logic for hold functionality; better suited for continuous comparison without state capture. | Select when lower power and absence of latch control simplifies design - verify external latching meets timing requirements. |
| LM339DR | Quad open-collector comparator; 1.3µs typical delay; no latch; wider supply range (2–36V); no TTL outputs. | Needs external pull-up and level translation for TTL interface; suitable for low-speed industrial monitoring. | Select for cost-sensitive, non-critical timing applications where microsecond response suffices and latch is unnecessary. |
Compared with MAX900BCPP, MAX9202BCPP offers identical speed and footprint with half the power and no latch - ideal for streaming comparison; LM339DR trades speed and integration for broad supply tolerance and cost, requiring external components to replicate TTL/latch functionality.

FAQ
What is the operating temperature range for MAX900BCPP?
The MAX900BCPP is specified for 0°C to +70°C operation. This commercial-grade temperature range is confirmed in the Maxim ordering information table and applies specifically to the "BC" grade suffix. The device uses a plastic DIP package rated for this range, and all electrical characteristics in the datasheet are guaranteed within these limits. MAX900BCPP does not support extended or industrial temperature grades.
Does MAX900BCPP support single-supply operation?
Yes, MAX900BCPP supports single-supply operation with VEE tied to GND and VCC set to +5V to +10V. Its input common-mode range extends to the negative rail (VEE − 0.1V), enabling ground-referenced sensing. The digital supply VDD remains fixed at +5V. This configuration is explicitly validated in the Applications Information section and Figure 1A of the datasheet.
Are the latch inputs on MAX900BCPP TTL-compatible?
Yes, the latch inputs (pins 4, 7, 14, 17) on MAX900BCPP are TTL-compatible, with VLH = 1.4–2.0V and VLL = 0.8–1.4V. These thresholds match standard TTL logic levels, allowing direct connection to LS-TTL or CMOS outputs without level shifting. Latch behavior - holding output state when driven low - is functional across the full operating temperature range and is documented in the Electrical Characteristics tables.
What is the maximum load capacitance supported by MAX900BCPP outputs?
MAX900BCPP outputs are characterized up to 15pF load capacitance, with propagation delay degradation remaining within specification (10ns max) under those conditions. The Typical Operating Characteristics graph "Response Time vs. Load Capacitance" shows tpd increasing to ~14ns at 50pF. For reliable 10ns performance, layout and routing should keep total node capacitance ≤15pF, including scope probe and PCB trace contributions.
Is MAX900BCPP recommended for new designs?
No, MAX900BCPP is Not Recommended for New Designs per Maxim's official notice. The process technology used to manufacture the MAX900 series is obsolete, and Maxim recommends the pin-compatible MAX9202BCPP as a replacement offering identical speed and half the power dissipation. While MAX900BCPP remains available for legacy support, new designs should evaluate MAX9202BCPP or other modern alternatives to ensure long-term supply continuity.
