Product details
Overview
TL3116CPWR from Texas Instruments is an ultra-fast, dual-supply or single-supply voltage comparator with complementary TTL-compatible outputs, 10 ns typical propagation delay, ±5-V or +5-V operation, and latch-enable functionality for synchronized decision capture. It serves in high-speed analog-to-digital interface circuits where precise ground-sensing and low-power timing-critical decisions are required.
For engineers reviewing the TL3116CPWR datasheet, TL3116CPWR pinout, TL3116CPWR application, or TL3116CPWR equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use scenarios, and two confirmed alternative comparators - all grounded in TI's SLCS132C datasheet and official packaging documentation.
Technical Context
The TL3116CPWR employs a bipolar input stage with rail-to-rail common-mode input range extending to the negative supply rail, enabling true ground-referenced sensing. Its internal latch circuit responds to the LATCH ENABLE terminal (pin 8), allowing synchronous sampling of comparator output states without external logic.
It delivers complementary Q and Q̅ outputs capable of directly driving TTL loads, with low-level output voltage ≤600 mV at 4 mA sink current and high-level output voltage ≥3.6 V at 1 mA source current. Propagation delay remains stable across ±5-V supplies (9.9–12 ns typ) and exhibits minimal pulse skew (≤0.5 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 10 ns typical at ±5-V supply and 100-mV overdrive - enables sub-100-MHz sampling decision loops. |
| Input offset voltage | 3 mV typical at 25°C - supports precision threshold detection within ±3 mV accuracy. |
| Supply range | Single +5 V or split ±5 V - simplifies power architecture in mixed-signal systems without level-shifting. |
| Common-mode input range | Extends to negative rail (−5 V) - allows direct sensing of signals referenced to ground or negative rails. |
| Latch enable threshold | VIH = 2 V, VIL = 0.8 V - compatible with standard TTL logic levels for reliable control signal interfacing. |
| Output drive capability | ±20 mA max output current - drives multiple TTL inputs or small capacitive loads without buffering. |
| Positive supply current | 12.7 mA typical at 25°C - achieves ultra-fast response with lower quiescent power than LT1116. |
Pinout & Package
TSSOP-8 package (PW), 3.0 mm × 4.4 mm body, 0.65 mm pitch, 1.2 mm max height, moisture sensitivity level 1, lead finish NiPdAu.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC+) | Positive supply input | Accepts +5 V (single supply) or +5 V (dual supply); must be decoupled near pin for high-speed stability. |
| 2 (IN+) | Non-inverting input | Differential input node with rail-to-rail common-mode range; bias current 0.7–1.1 µA typical. |
| 3 (IN−) | Inverting input | Differential input node; matched to IN+ for low offset and high CMRR (75–100 dB). |
| 4 (VCC−) | Negative supply input | Accepts −5 V in dual-supply mode; floats or ties to GND in single-supply +5-V configuration. |
| 5 (Q OUT) | True output | Active-high TTL-compatible output; sinks up to 4 mA while maintaining VOL ≤ 600 mV. |
| 6 (Q̅ OUT) | Complementary output | Active-low inverted copy of Q OUT; enables differential signaling or OR/NOR logic without external inverters. |
| 7 (GND) | Ground reference | System ground return path; separates analog and digital grounds only if layout demands isolation. |
| 8 (LATCH ENABLE) | Asynchronous latch control | High-valid enable: asserts latched state on rising edge; VIH = 2 V ensures noise margin vs. TTL logic. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast propagation | 10 ns typical delay enables real-time overvoltage/undervoltage fault detection in power converters. |
| Rail-to-rail input common-mode | Includes negative rail (−5 V), supporting ground-sensing in battery-monitoring and motor-control feedback paths. |
| Complementary TTL outputs | Q and Q̅ eliminate need for external inverters in window-comparator or flip-flop clocking applications. |
| Integrated latch function | LATCH ENABLE (pin 8) captures instantaneous comparator state - critical for synchronized ADC trigger or event logging. |
| Low power at speed | 12.7 mA ICC at 10 ns delay - consumes ~40% less supply current than LT1116 at comparable speed. |
Applications
| Overvoltage Protection Circuit | High-Speed Data Acquisition Trigger |

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-for-pin compatible but draws 22 mA typical ICC; 12 ns propagation delay; no latch-enable function. | Lacks integrated latch; requires external D-flip-flop for synchronized sampling - increases board area and propagation uncertainty. | Choose when legacy drop-in replacement is mandatory and latch functionality is implemented externally. |
| TL3116IDR | Same die, SOIC-8 package; extended temperature range (−40°C to +85°C); identical electrical specs and pinout. | SOIC-8 footprint requires larger PCB area and higher thermal resistance vs. TSSOP-8; not suitable for space-constrained layouts. | Choose for industrial ambient environments where extended temp rating is required and board space permits SOIC. |
Compared with LT1116CS8#PBF, TL3116CPWR reduces supply current by 42% and adds latch control; compared with TL3116IDR, it offers identical performance in a 35% smaller footprint with superior thermal dissipation - making it optimal for compact, power-sensitive, and timing-critical designs.

FAQ
What is the maximum operating temperature range for the TL3116CPWR?
The TL3116CPWR is rated for operation from 0°C to +70°C ambient temperature, as confirmed in the "AVAILABLE OPTIONS" table and absolute maximum ratings section of the SLCS132C datasheet. This commercial-grade temperature range applies specifically to the CPWR variant; the 'I' grade (e.g., TL3116IPWR) extends to −40°C to +85°C.
Can the TL3116CPWR operate from a single +5-V supply?
Yes, the TL3116CPWR supports single +5-V supply operation per its datasheet description and electrical characteristics tables. In this configuration, VCC+ (pin 1) connects to +5 V, VCC− (pin 4) and GND (pin 7) both connect to system ground, and the input common-mode range becomes 0 V to +2.5 V.
Does the TL3116CPWR require external pull-up resistors on its outputs?
No, the TL3116CPWR features active push-pull outputs capable of sourcing up to 1 mA and sinking up to 4 mA while maintaining valid TTL logic levels (VOH ≥ 3.6 V, VOL ≤ 600 mV). External pull-ups are unnecessary unless driving heavier capacitive loads or non-TTL logic families.
How does the LATCH ENABLE function work on the TL3116CPWR?
The LATCH ENABLE terminal (pin 8) is an asynchronous control input: when driven high (≥2 V), it freezes the current logic state of Q and Q̅ outputs; when low (≤0.8 V), outputs respond dynamically to input changes. This enables precise timing capture independent of comparator propagation delay.
Is the TL3116CPWR RoHS compliant and what is its MSL rating?
Yes, the TL3116CPWR is RoHS compliant (lead finish NiPdAu) and carries a Moisture Sensitivity Level (MSL) rating of Level-1 at 260°C peak reflow, as documented in TI's official Package Option Addendum. This allows indefinite floor life without dry-pack requirements prior to assembly.
