Product details
Overview
TL3116IPWR from Texas Instruments is an ultra-fast, rail-to-rail input comparator with complementary TTL-compatible outputs, 10 ns typical propagation delay, ±5-V or single 5-V supply operation, and latch-enable functionality - used in high-speed analog-to-digital interfacing, precision zero-crossing detection, and pulse-width modulation feedback loops.
For engineers reviewing the TL3116IPWR datasheet, TL3116IPWR pinout, TL3116IPWR application, or TL3116IPWR equivalent, key selection criteria include propagation delay vs. overdrive voltage, input common-mode range extending to negative rail, latch timing (3.4 ns setup), output drive capability (±20 mA), and TSSOP-8 thermal performance under industrial temperature range (−40°C to +85°C).
Technical Context
The TL3116IPWR implements a bipolar differential input stage with high open-loop gain (>100 dB) and tightly controlled offset voltage (≤3 mV typ), enabling precise threshold detection even at low overdrive. Its complementary Q and Q̅ outputs support direct TTL/CMOS interfacing without external level-shifting.
Latch enable functionality allows synchronous capture of comparator state with 3.4 ns setup time relative to input transition; internal biasing ensures stable operation across −40°C to +85°C without external compensation. Input common-mode range includes the negative rail (−5 V), supporting ground-referenced sensing in single-supply configurations.
Key Specifications

|---|---|
| Propagation delay | 10 ns typical at 100 mV overdrive - enables sub-100 MHz sampling decision timing in ADC front-ends. |
| Input offset voltage | 3 mV max over full temperature range - ensures ≤0.5% threshold error in 0.6 V reference applications. |
| Supply range | Single 5 V or split ±5 V - supports legacy 5-V logic domains and isolated analog signal chains. |
| Output drive | ±20 mA sink/source - directly drives 50-Ω transmission lines or TTL inputs without buffer stages. |
| Common-mode range | Extends to negative rail (−5 V) - enables accurate ground-sensing in motor current monitoring and battery protection circuits. |
| Latch setup time | 3.4 ns - synchronizes comparator output to system clock edges with minimal timing margin loss. |
| Supply current | 12.7 mA typical (±5 V) - achieves ultra-fast response at <13 mA, reducing thermal load in dense PCB layouts. |
Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm max height, RoHS-compliant NIPDAU lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC+ | Positive supply terminal | Accepts +5 V (single supply) or +5 V (dual supply); decoupling required within 1 cm for stable 10 ns switching. |
| 2 - IN+ | Non-inverting input | Differential input node with 1.2 µA max bias current; supports rail-to-rail common-mode swing down to −5 V. |
| 3 - IN− | Inverting input | Matches IN+ in offset and bias; differential input voltage limited to ±7 V absolute maximum. |
| 4 - VCC− | Negative supply terminal | Accepts 0 V (single supply) or −5 V (dual supply); connects to system ground or negative rail. |
| 5 - Q OUT | True output | Active-high TTL-compatible output; sinks 4 mA at 600 mV VOH, sources 1 mA at 3.9 V VOH. |
| 6 - Q̅ OUT | Complementary output | Active-low mirror of Q OUT; enables differential signaling or wired-OR logic without external inverters. |
| 7 - GND | Ground reference | Low-impedance return path for output currents; must be tied to same plane as VCC− for noise immunity. |
| 8 - LATCH ENABLE | Asynchronous latch control | Active-high enable; latches Q/Q̅ state on rising edge with 3.4 ns setup - critical for synchronized sampling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1116CS8#PBF | Pin-compatible but higher supply current (25 mA typ), slower propagation delay (15 ns), no latch enable. | Lacks synchronous latch; requires external flip-flop for sampled decision - increases board area and timing uncertainty. | Choose only if legacy LT1116 footprint reuse is mandatory and latch functionality is unnecessary. |
| LMH7322MA/NOPB | 3.3 V–5.5 V supply, 4.5 ns delay, differential LVDS outputs, no latch, 100 mA output drive. | Designed for high-speed serial links; incompatible TTL output levels and missing latch control limit use in control logic. | Select when sub-5 ns timing is critical and system uses LVDS receivers; not suitable for TTL/CMOS interfacing or latched sampling. |
Compared with LT1116CS8#PBF and LMH7322MA/NOPB, TL3116IPWR uniquely balances 10 ns speed, latch-enable synchronization, TTL compatibility, and −40°C to +85°C operation in a space-efficient TSSOP-8 package - making it optimal for industrial control, power management, and test equipment where deterministic timing and robustness are essential.

FAQ
What is the maximum operating temperature range for TL3116IPWR?
The TL3116IPWR is rated for operation from −40°C to +85°C ambient temperature, validated across electrical parameters including propagation delay, offset voltage, and output drive strength. This industrial temperature grade makes TL3116IPWR suitable for under-hood automotive modules, factory automation controllers, and outdoor communications infrastructure where thermal stability is critical.
Does TL3116IPWR support single-supply operation?
Yes, TL3116IPWR operates from a single 5-V supply with input common-mode voltage range from 0 V to +2.5 V, and output logic levels compatible with TTL. When using single supply, VCC− (Pin 4) must be connected to ground, and GND (Pin 7) serves as the reference return - enabling simplified power architecture in 5-V-only systems without negative rails.
How does the latch enable function work on TL3116IPWR?
The LATCH ENABLE terminal (Pin 8) is an asynchronous active-high control that captures and holds the instantaneous logic states of Q OUT and Q̅ OUT. When asserted, the outputs freeze regardless of further input changes; deassertion releases the latch. TL3116IPWR requires only 3.4 ns setup time before the latch enable rising edge to guarantee correct state capture - essential for synchronized sampling in FPGA-based systems.
What is the absolute maximum differential input voltage for TL3116IPWR?
The absolute maximum differential input voltage (IN+ to IN−) for TL3116IPWR is ±7 V, as specified in the Absolute Maximum Ratings table. Exceeding this limit risks permanent damage to the input stage. For reliable operation, differential input should remain within ±5 V under normal conditions, with design margins maintained per TI's recommended operating conditions.
Is TL3116IPWR pin-compatible with any other comparators?
TL3116IPWR is pin-compatible with the LT1116 in TSSOP-8 (PW) package - sharing identical pin assignments for VCC+, IN+, IN−, VCC−, Q OUT, Q̅ OUT, GND, and LATCH ENABLE. However, TL3116IPWR adds latch functionality absent in LT1116, and draws less than half the supply current (12.7 mA vs. 25 mA) at comparable speed, making it a functional upgrade rather than drop-in replacement unless latch use is disabled.
