Product details
Overview
TLC393IPWG4 from Texas Instruments is a dual micropower voltage comparator with open-drain CMOS outputs, designed for single-supply operation from 3 V to 16 V. It delivers 110 µW typical supply power at 5 V, 2.5 µs typical propagation delay (tPLH) with 5-mV overdrive, and 5 mV max input offset voltage at 25°C - enabling precision threshold detection in battery-powered sensor interfaces and power supervision circuits.
For engineers reviewing the TLC393IPWG4 datasheet, TLC393IPWG4 pinout, TLC393IPWG4 application, or TLC393IPWG4 equivalent, key selection criteria include industrial-temperature operation (−40°C to +85°C), rail-to-rail common-mode input range (0 V to VDD − 1.5 V), low input bias current (≤0.6 nA at 70°C), and compatibility with pull-up loads up to 16 V.
Technical Context
The TLC393IPWG4 implements two independent comparators fabricated using Texas Instruments' LinCMOS™ process, delivering high input impedance (>1012 Ω), stable input offset voltage under differential stress, and immunity to latch-up. Its open-drain output stage requires external pull-up for logic-level translation across voltage domains.
It operates without phase reversal under common-mode input stress and maintains functional integrity with inputs extending 0.3 V beyond supply rails (within ±5 mA current limit). The device is characterized for full industrial temperature range (−40°C to +85°C) and supports supply voltages as low as 3 V while retaining sub-µs response at moderate overdrive.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
TLC393IPWG4 is housed in a TSSOP-8 (PW) package with 0.65 mm pitch, 3.0 mm × 4.4 mm body, and exposed pad (non-electrical). Pin 1 is marked by a dot; pin numbering follows standard counter-clockwise orientation when viewed from top.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-drain output of comparator 1 - requires external pull-up; sinks up to 20 mA. |
| 2 | IN1− | Inverting input of comparator 1 - high-impedance node; accepts DC or AC signals within common-mode range. |
| 3 | IN1+ | Non-inverting input of comparator 1 - used for reference or signal comparison; matched to IN1− for offset minimization. |
| 4 | GND | Analog ground reference - must be connected directly to system ground plane with low-inductance path. |
| 5 | VDD | Positive supply rail - decoupling capacitor (0.1 µF) required adjacent to pin for noise immunity. |
| 6 | OUT2 | Open-drain output of comparator 2 - independently controllable; shares no internal connection with OUT1. |
| 7 | IN2− | Inverting input of comparator 2 - electrically isolated from comparator 1; supports dual independent thresholds. |
| 8 | IN2+ | Non-inverting input of comparator 2 - enables simultaneous monitoring of two distinct analog conditions. |

IC Role / Device Role / Timing Role: Cross-coupled comparators with RC timing network produce complementary, dead-time-controlled outputs. Use Value: Sub-µs propagation delay matching between channels minimizes timing skew; 110 µW quiescent power extends standby time. |
Use Scenario: Threshold detection in battery-operated gas or temperature sensors with high-impedance output (e.g., thermistors, electrochemical cells). IC Role / Device Role / Timing Role: Comparator compares sensor voltage against precision reference; output drives wake-up interrupt or LED indicator. Use Value: 2 nA max input bias at +85°C prevents measurement error in MΩ-range sensor networks; rail-to-rail input accommodates full sensor swing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher supply current (500 µA typ), wider offset voltage (7 mV max over 0°C–70°C only), no guaranteed operation above 70°C. | Limited to commercial-temperature applications; unsuitable for industrial environments requiring −40°C startup. | Select LM393DR only for cost-sensitive, ambient-temperature consumer products where ultra-low power is not critical. |
| TLC3702CDR | Push-pull output (no external pull-up needed), faster tPLH (1.5 µs typ), but higher supply current (120 µA typ) and narrower VDD range (3 V–16 V same). | Eliminates pull-up resistors but lacks open-drain flexibility for wired-OR or mixed-voltage logic interfacing. | Choose TLC3702CDR when driving CMOS loads directly and board space is constrained; avoid when interfacing with 3.3 V µP from 12 V rail. |
Compared with LM393DR and TLC3702CDR, the TLC393IPWG4 uniquely balances industrial-temperature reliability, micropower operation (<65 µA), and open-drain versatility - making it optimal for long-life, multi-rail, and harsh-environment sensing systems.
