Product details
Overview
LT1016CS8#PBF from Analog Devices is an ultrafast 10ns precision comparator with complementary TTL/CMOS-compatible outputs, ±5V or single 5V supply operation, 1.0mV max input offset voltage, and integrated LATCH pin for data retention. It serves as a high-speed decision element in A/D converters, pulse discriminators, and zero-crossing detectors.
For engineers reviewing the LT1016CS8#PBF datasheet, LT1016CS8#PBF pinout, LT1016CS8#PBF application, or LT1016CS8#PBF equivalent, key selection considerations include propagation delay under low overdrive (9–16ns), latch setup time (2ns), output drive capability into passive loads, stable linear-region operation, and SO-8 package compatibility with industrial temperature range (0°C to 70°C).
Technical Context
The LT1016CS8#PBF employs a high-gain-bandwidth (≈50GHz) NPN input stage enabling nanosecond response to millivolt-level signals without minimum slew rate requirements. Its unique active-output stage delivers bidirectional drive into TTL/CMOS or passive loads while eliminating current spikes that cause output glitching.
Internal LATCH functionality retains output state when the LATCH pin is high, requiring ≥2ns setup time and supporting TTL/CMOS logic drive. Common-mode input range is –3.75V to 3.5V (±5V supplies) or 1.25V above V– and 1.5V below V+, with guaranteed performance across 0°C to 70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 9–16ns (100mV step, 5–20mV overdrive); enables sub-100MHz sampling in SAR ADCs |
| Input Offset Voltage | ≤1.0mV (max, C grade); supports precision threshold detection at mV-level resolution |
| Supply Range | Single 5V or ±5V; negative supply current only 3mA, allowing resistive divider biasing |
| Output Type | Complementary Q/Q̅; drives TTL/CMOS directly without external level-shifting |
| LATCH Pin Function | Retains output state when high; requires 2ns setup time; no internal hysteresis |
| Common-Mode Range | –3.75V to 3.5V (±5V); extends to 1.25V above V– and 1.5V below V+ for non-standard supplies |
| Gain-Bandwidth Product | ≈50GHz; ensures fast settling even with low-amplitude differential inputs |
Pinout & Package
LT1016CS8#PBF is housed in an 8-lead plastic SO (Small Outline) package, RoHS-compliant, with θJA = 120°C/W and TJMAX = 110°C.

| 6 (Q̅ OUT) | Complementary Output | Active-low mirror of Q; enables direct connection to differential receivers |
| 7 (GND) | Ground Reference | Low-impedance return path; must be connected with ≤1/4″ trace for stability |
| 8 (LATCH) | Data Retention Control | High = latch enabled; VIH ≥2.0V; draws ≤500µA when low |
Key Features

Applications
| High-Speed A/D Converters | Zero-Crossing Detectors |
|---|---|
Use Scenario: Used in 1.8µs 12-bit successive approximation ADCs where speed and precision are critical. IC Role / Device Role / Timing Role: Acts as window comparator controlling SAR clock rate and latching conversion completion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM360N | Slower (25ns typ), no LATCH pin, wider offset (±2mV), PDIP-only packaging | Lacks data retention; unsuitable for synchronous sampling or pipelined architectures | Select LM360N only for cost-sensitive, non-latched, lower-speed designs where SO-8 footprint is not required |
| MAX961ASA+ | Faster (4.5ns typ), rail-to-rail inputs, no complementary outputs, different pinout (8-pin SO) | Requires external inverters for Q̅; incompatible with legacy LT1016 PCB layouts | Choose MAX961ASA+ when <5ns delay is mandatory and board redesign is acceptable |
Compared with LM360N and MAX961ASA+, the LT1016CS8#PBF uniquely balances 10ns speed, latch functionality, complementary outputs, and SO-8 compatibility-making it optimal for upgrading existing ±5V comparator designs without layout changes.

FAQ
What is the maximum operating temperature range for the LT1016CS8#PBF?
The LT1016CS8#PBF is rated for 0°C to 70°C ambient operation (C grade). Its SO-8 package has a junction-to-ambient thermal resistance (θJA) of 120°C/W, and maximum junction temperature is 110°C. Derating is required above 70°C ambient unless heatsinking or airflow is applied.
Does the LT1016CS8#PBF require external pull-up resistors on its Q and Q̅ outputs?
No, the LT1016CS8#PBF does not require external pull-up resistors. Its active-output stage provides full rail-to-rail sourcing and sinking capability: VOH ≥2.7V at 1mA and VOL ≤0.5V at 10mA into TTL/CMOS loads. Pull-ups would degrade speed and increase power consumption.
Can the LT1016CS8#PBF operate from a single 3.3V supply?
No-the LT1016CS8#PBF is not specified for 3.3V operation. Absolute maximum positive supply is 7V, but electrical characteristics (propagation delay, offset, output swing) are only guaranteed for ±5V or single 5V supplies per the datasheet. Operation at 3.3V may result in undefined timing, reduced noise margin, or failure to meet 10ns spec.
How does the LATCH pin function in the LT1016CS8#PBF, and what are its timing requirements?
The LATCH pin on the LT1016CS8#PBF holds the current output state when driven high. It requires a minimum 2ns setup time before the latch-enable edge and remains transparent when low. The pin accepts TTL/CMOS logic levels (VIH ≥2.0V, VIL ≤0.8V) and draws ≤500µA when low. No internal hysteresis is present.
Is the LT1016CS8#PBF pin-compatible with the LT1016CN8#PBF?
Yes-the LT1016CS8#PBF (SO-8) and LT1016CN8#PBF (PDIP-8) share identical pin functions and electrical specifications. However, they differ in package type, thermal performance (θJA = 120°C/W vs. 130°C/W), and mounting method. PCB layout must accommodate SO-8 footprint and reflow profile.
