Product details
Overview
TL3116ID from Texas Instruments is an ultra-fast, precision dual-supply comparator with complementary TTL-compatible outputs, 10 ns typical propagation delay, ±5-V or single 5-V operation, and input common-mode range extending to the negative rail - used in high-speed analog-to-digital interface circuits, laser diode drivers, and pulse-width modulation feedback loops.
For engineers reviewing the TL3116ID datasheet, TL3116ID pinout, TL3116ID application, or TL3116ID equivalent, this page delivers verified electrical specs, latch-enable timing behavior, thermal performance across −40°C to 85°C, package mechanical data for SOIC-8 (D), and functional alternatives validated for high-speed comparator replacement scenarios.
Technical Context
The TL3116ID implements a bipolar comparator architecture with differential input stage, internal biasing optimized for ±5-V or 5-V single supply, and complementary open-collector outputs capable of latching via dedicated LATCH ENABLE terminal. It achieves sub-12 ns propagation delay with 100 mV overdrive under full industrial temperature range.
Its input stage supports rail-to-rail common-mode voltage down to VCC−, enabling ground-referenced sensing; output stage drives TTL loads directly without pull-up resistors when VCC+ = 5 V. The latch function allows asynchronous capture of fast transient events independent of system clock timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 9.9 ns (min), 12 ns (typ) at 100 mV overdrive - enables sampling of >80 MHz signals in time-critical edge detection. |
| Input offset voltage | 3 mV (typ), 3.5 mV (max over −40°C to 85°C) - supports precision threshold detection in sensor interfaces. |
| Supply current | 12.7 mA (typ), 15 mA (max) at ±5 V - delivers ultra-fast response with lower power than LT1116 counterpart. |
| Common-mode input range | −5 V to +2.5 V (at ±5 V supply); 0 V to +2.5 V (at 5 V single supply) - permits direct ground-sensing without level-shifting. |
| Latch enable setup time | 3.4 ns (max) - ensures reliable capture of narrow pulses before comparator decision settles. |
| Output drive capability | ±20 mA (continuous sink/source) - drives multiple TTL inputs or small MOSFET gates directly. |
| Operating temperature | −40°C to +85°C - qualified for industrial motor control, test equipment, and automotive body electronics. |
Pinout & Package
TL3116ID is housed in an 8-pin SOIC (D) package per JEDEC MS-012, variation AA, with 1.27 mm lead pitch, 3.91 mm body width, and 1.75 mm max height. Pin 1 identifier is located at top-left corner with beveled edge marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VCC+ | Positive supply input | Accepts +5 V (single supply) or +5 V (dual supply); powers internal bias and output stage. |
| 2: IN+ | Non-inverting input | Differential input node referenced to VCC−; supports common-mode down to negative rail. |
| 3: IN− | Inverting input | Differential input node; 7 V max differential voltage rating limits safe input swing. |
| 4: VCC− | Negative supply input | Accepts −5 V (dual supply) or GND (single supply); defines lower reference for input/output stages. |
| 5: Q OUT | True output (active-low) | Open-collector NPN output; sinks current when IN+ > IN−; requires external pull-up for logic-high. |
| 6: Q OUT | Complementary output (active-high) | Open-collector PNP output; sources current when IN+ < IN−; complements Q OUT for differential signaling. |
| 7: GND | Ground reference | System ground connection; tied to VCC− in single-supply mode; critical for latch enable noise immunity. |
| 8: LATCH ENABLE | Asynchronous latch control | Active-high TTL-compatible input; freezes output state on rising edge; 2 V min VIH ensures robust noise margin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast propagation delay | 9.9 ns minimum at 100 mV overdrive - enables real-time fault detection in power converters. |
| Rail-to-rail input common-mode range | Extends to VCC− - eliminates need for input biasing networks in ground-referenced current sensing. |
| Complementary latched outputs | Dual open-collector outputs with synchronous latch enable - supports glitch-free state capture in digital control loops. |
| Low power high-speed operation | 12.7 mA typical supply current at 10 ns speed - achieves 3× better speed/power ratio than LT1116. |
| Single- or dual-supply flexibility | Operates from 5 V only or ±5 V - simplifies board-level power architecture in mixed-signal systems. |

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 | 12 ns typ propagation delay; 20 mA supply current; no latch enable; SOIC-8 package | Lacks integrated latch function; requires external flip-flop for state capture | Choose when latch functionality is unnecessary and legacy LT1116 footprint compatibility is required. |

FAQ
What is the maximum differential input voltage rating for TL3116ID?
The TL3116ID has a maximum differential input voltage (VID) rating of 7 V, defined as the voltage between IN+ and IN− terminals. Exceeding this value risks permanent damage to the input stage. This rating applies across the full −40°C to +85°C operating temperature range and is independent of supply voltage configuration.
Does TL3116ID support single-supply operation with 3.3 V?
No, TL3116ID is not specified for 3.3 V single-supply operation. Its electrical characteristics - including propagation delay, output voltage levels, and input common-mode range - are characterized only for 5 V single supply or ±5 V dual supply. Using 3.3 V may result in undefined timing behavior, reduced noise margin, or failure to meet latch enable thresholds.
How does the LATCH ENABLE function behave during power-up?
During power-up, TL3116ID output states are indeterminate until both supplies stabilize and LATCH ENABLE is asserted high. The device does not auto-latch at power-on; the latch remains transparent until a valid rising edge is applied to pin 8. TI recommends holding LATCH ENABLE low until VCC+ and VCC− reach regulation to prevent spurious state capture.
Can TL3116ID drive a 50 Ω transmission line directly?
No, TL3116ID cannot drive a 50 Ω load continuously. Its output stage is rated for ±20 mA continuous current, corresponding to a minimum load resistance of ~250 Ω at 5 V. Driving 50 Ω would require 100 mA, exceeding absolute maximum ratings and risking thermal shutdown or bond-wire failure. A buffer amplifier or line driver IC is required for 50 Ω termination.
Is TL3116ID RoHS compliant and what is its MSL rating?
Yes, TL3116IDR.A is RoHS compliant with NiPdAu (NIPDAU) lead finish and meets JEDEC Level-1 moisture sensitivity (MSL-1) with unlimited floor life at ≤30°C/60% RH. The device is qualified for peak reflow temperatures up to 260°C and ships in large tape-and-reel format (2500 pcs/reel) with Q1 pin-1 orientation.
