Product details
Overview
LT1016CS8#TRPBF 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 where nanosecond timing and low-glitch behavior are critical.
For engineers reviewing the LT1016CS8#TRPBF datasheet, LT1016CS8#TRPBF pinout, LT1016CS8#TRPBF application, or LT1016CS8#TRPBF equivalent, key selection considerations include propagation delay (10ns typ), latch setup time (2ns), output drive capability into passive loads, absence of supply current spiking, and stable linear-region operation - all verified under ±5V and single 5V supply conditions.
Technical Context
The LT1016CS8#TRPBF employs a high-gain-bandwidth (≈50GHz) NPN input stage with matched complementary outputs, enabling precise threshold detection without minimum input slew rate requirements. Its unique active-output stage drives both logic high and low states without current spikes, eliminating output "glitching" during slow or low-level input transitions.
Internal biasing allows stable operation across supply variations: negative supply current remains constant at 3mA (typ), permitting resistive divider derivation of V–, while common-mode range is defined as 1.25V above V– and 1.5V below V+, independent of absolute supply voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 10ns typical at 5mV overdrive - enables sub-100MHz sampling in SAR ADCs and fast pulse discrimination. |
| Input Offset Voltage | ±3.5mV max - supports precision thresholding in V-to-F converters and current-sense circuits. |
| Supply Range | Single 5V or ±5V - simplifies power architecture in mixed-signal systems without dedicated negative rails. |
| LATCH Pin Threshold | 2.0V VIH / 0.8V VIL - directly compatible with TTL/CMOS logic for synchronous data capture. |
| Output Drive | VOH = 2.7V @ 1mA, VOL = 0.3V @ 4mA - ensures robust interfacing to 74S/74LS logic families. |
| Common-Mode Range | –3.75V to +3.5V (±5V supplies) - accommodates wide-input-range signal conditioning before digitization. |
| Negative Supply Current | 3mA typ - enables V– generation via resistor divider from positive rail, reducing BOM count. |
Pinout & Package
LT1016CS8#TRPBF is housed in an 8-lead plastic SOIC (S8) package with 1.27mm pitch, JEDEC MS-012AC compliant, thermal resistance θJA = 120°C/W, and rated for 0°C to 70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (V+) | Positive supply input | Accepts 4.6V–5.4V for stable operation; PSRR ≥ 60dB ensures noise immunity. |
| 2 (+IN) | Non-inverting input | DC-coupled analog input; input bias current ≤ 13µA, impedance ≈ 4MΩ common-mode. |
| 3 (–IN) | Inverting input | Differential partner to +IN; supports rail-to-rail common-mode input when other input is within limits. |
| 4 (V–) | Negative supply input | Accepts –7V to 0V; quiescent current 3mA enables simple resistive derivation from V+. |
| 5 (Q OUT) | True output | Active-high complementary TTL output; sinks 4mA min, sources 1mA min. |
| 6 (Q OUT) | Complementary output | Active-low inversion of Q; eliminates external inverters in latch-based sampling circuits. |
| 7 (GND) | Ground reference | Low-impedance return path; layout requires direct connection to ground plane ≤¼ inch. |
| 8 (LATCH) | Data retention control | High = latched state; 2ns setup time required; floats high if unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| Ultrafast 10ns response | Enables 100MHz+ sampling in high-speed A/D architectures without added latency. |
| No power supply current spiking | Eliminates need for oversized bypass capacitors and prevents supply-induced oscillation. |
| Stable linear-region operation | Permits use in analog comparators with slow-moving inputs without output instability. |
| Matched complementary outputs | Reduces component count in edge-triggered logic interfaces and differential receivers. |
| LATCH pin with 2ns setup | Supports synchronous sampling in pipelined ADCs and time-of-flight measurement systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM360N | 25ns propagation delay, no LATCH pin, ±15V supply capable | Suitable for high-voltage industrial sensing but lacks synchronous sampling capability | Select when >10ns delay is acceptable and latch functionality is unnecessary |
| MAX961ASA+ | 4.5ns propagation delay, rail-to-rail inputs, 2.7V–5.5V supply only | Optimized for low-voltage portable systems; incompatible with ±5V operation | Select for battery-powered designs requiring sub-5ns timing and single-supply simplicity |
Compared with LM360N and MAX961ASA+, the LT1016CS8#TRPBF uniquely balances 10ns speed, ±5V/single-5V flexibility, latch-enabled synchronous sampling, and stable linear-region operation - making it irreplaceable in precision high-speed sampling and zero-crossing applications demanding deterministic timing.

FAQ
What is the maximum operating temperature range for the LT1016CS8#TRPBF?
The LT1016CS8#TRPBF is specified for operation from 0°C to 70°C ambient temperature. This commercial-grade temperature range is confirmed in the Absolute Maximum Ratings table and Order Information section of the official datasheet. The device uses an 8-lead plastic SOIC (S8) package with θJA = 120°C/W, and its junction temperature must not exceed 110°C under continuous operation. Derating curves in Figure G10 show negative supply current remains stable across this full range.
Does the LT1016CS8#TRPBF require external hysteresis for stable operation with slow-moving inputs?
No, the LT1016CS8#TRPBF does not require external hysteresis. Its internal architecture provides stable linear-region operation - a feature explicitly highlighted in the Applications Information section. Unlike conventional comparators, the LT1016CS8#TRPBF remains stable even when inputs are slow-moving or near the decision threshold, eliminating output "glitching" without added components. This is enabled by its unique active-output stage and absence of supply current spiking.
Can the LT1016CS8#TRPBF operate from a single 3.3V supply?
No, the LT1016CS8#TRPBF is not specified for 3.3V-only operation. Electrical characteristics are guaranteed only for single 5V (V+ = 5V, V– = 0V) or dual ±5V supplies, per the Conditions column in the Electrical Characteristics table. Absolute maximum ratings allow V+ up to 7V and V– down to –7V, but performance parameters like propagation delay, offset voltage, and output drive are not characterized below 4.6V on V+. Using 3.3V risks violating VOH/VOL specifications and degrading timing accuracy.
How does the LATCH pin function in the LT1016CS8#TRPBF, and what timing constraints apply?
The LATCH pin on the LT1016CS8#TRPBF retains the current comparator output state when driven high. Data must be valid at least 2ns before the LATCH signal rises (setup time), and remain valid for 3ns after (hold time). When LATCH goes low, new input data appears at outputs in 8–10ns. The pin accepts standard TTL/CMOS logic levels (VIH ≥ 2.0V, VIL ≤ 0.8V) and draws ≤500µA at 0V. It floats high when unconnected, so grounding is required for flowthrough mode.
Is the LT1016CS8#TRPBF pin-compatible with the LT1016CN8#PBF?
Yes, the LT1016CS8#TRPBF and LT1016CN8#PBF share identical pinouts and electrical specifications, differing only in package type (8-lead SOIC vs. 8-lead PDIP) and temperature grade (0°C to 70°C for both). Both devices follow the same N8/S8 package pin configuration shown in the datasheet's PIN CONFIGURATION section, with V+, +IN, –IN, V–, Q, Q̅, GND, and LATCH assigned to pins 1–8 respectively. Mechanical dimensions differ, but PCB footprint and signal routing are functionally interchangeable.
