Product details
Overview
TLC393IPE4 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 maximum input offset voltage across −40°C to 85°C - enabling precision threshold detection in battery-powered industrial sensors and power supervision circuits.
For engineers reviewing the TLC393IPE4 datasheet, TLC393IPE4 pinout, TLC393IPE4 application, or TLC393IPE4 equivalent, key selection considerations include its industrial-temperature-rated LinCMOS™ process, rail-to-rail common-mode input range (0 V to VDD − 1.5 V), low 1 pA typical input bias current at 25°C, and compatibility with pull-up loads up to 16 V.
Technical Context
The TLC393IPE4 implements two independent comparators 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 resistors and supports mixed-voltage interfacing - e.g., 5-V logic driving 12-V loads.
It operates without phase reversal over its full common-mode input range (−0.2 V to VDD − 1.5 V at TA = −40°C to 85°C), and features on-chip ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2 - critical for reliability in noisy industrial environments.

|---|---|
Use Scenario: Pulse-width-modulated (PWM) control of DC motors in industrial actuators using potentiometer-adjusted reference and feedback voltage. IC Role / Device Role / Timing Role: Dual comparator configures as oscillator and duty-cycle comparator - one section generates triangle wave, the other compares against setpoint. Use Value: Micropower operation extends battery life; open-drain outputs interface directly to half-H drivers (e.g., SN75603/4) without level shifters. | Use Scenario: Monitoring 5-V and 12-V rails in embedded controllers to generate early power-fail interrupt and hardware reset signals. IC Role / Device Role / Timing Role: One comparator detects undervoltage on 5-V rail; second monitors 12-V rail - both feed µP interrupt and TL7705A reset generator. Use Value: Rail-to-rail input range enables direct sensing without resistor dividers; low IDD minimizes loading on monitored supplies. |
| Two-Phase Clock Generation | Threshold Detection in Sensor Interfaces |
Use Scenario: Generating nonoverlapping clock phases for synchronous rectifiers or gate drivers in switching regulators. IC Role / Device Role / Timing Role: Cross-coupled configuration forms astable multivibrator - each comparator's output drives the other's inverting input via RC network. Use Value: Propagation delay matching between sections ensures precise dead-time control; low offset minimizes phase skew. | Use Scenario: Converting analog sensor outputs (e.g., thermistor voltage divider, photodiode transimpedance amplifier) into digital logic levels. IC Role / Device Role / Timing Role: Comparator acts as precision voltage threshold detector - triggers state change when sensor crosses preset trip point. Use Value: 1 pA input bias current prevents loading of high-Z sensor sources; 7 mV max VIO ensures <0.1% error at 10-V full scale. |
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 VIO range (±7 mV), no LinCMOS - higher input bias current (25 nA). | Less suitable for ultra-low-power or high-impedance sensor interfaces; acceptable for cost-sensitive commercial designs. | Select LM393DR only when power budget >100 µA and sensor source impedance <100 kΩ. |
| TLC3702CP | Push-pull output (no external pull-up needed), faster tPLH (1.5 µs), but higher IDD (120 µA typ) and narrower temp range (0°C to 70°C). | Preferred where active-high logic drive is required and industrial temperature rating is not mandatory. | Choose TLC3702CP when eliminating pull-up resistors outweighs temperature and power trade-offs. |
Compared with LM393DR and TLC3702CP, the TLC393IPE4 uniquely balances micropower consumption (65 µA max), industrial temperature rating, and LinCMOS input performance - making it optimal for long-life, high-precision, mixed-voltage industrial sensing and control.

FAQ
What is the maximum supply voltage for the TLC393IPE4?
The TLC393IPE4 supports a supply voltage range of 3 V to 16 V, with absolute maximum rating at −0.3 V to 18 V. Operation above 16 V risks exceeding recommended conditions and may degrade long-term reliability. The device is commonly used at 5 V or 12 V in industrial power supervision and motor control applications, and the TLC393IPE4 maintains specified performance across this full range.
Does the TLC393IPE4 require external pull-up resistors on its outputs?
Yes, the TLC393IPE4 features open-drain CMOS outputs and requires external pull-up resistors to define the high-state voltage level. Pull-up values typically range from 2.2 kΩ to 10 kΩ depending on speed and load requirements. The TLC393IPE4 outputs can sink up to 20 mA and tolerate pull-up voltages up to 16 V - enabling direct interface with higher-voltage logic or discrete FET gates without level shifters.
What is the input offset voltage specification for the TLC393IPE4 over temperature?
The TLC393IPE4 has a maximum input offset voltage of 7 mV over the full industrial temperature range of −40°C to +85°C. At 25°C, typical VIO is 1.4 mV with a maximum of 5 mV. This tight offset ensures reliable threshold detection in precision applications such as supply monitoring and sensor signal conditioning - and the TLC393IPE4 maintains this spec without calibration across its rated operating range.
Can the TLC393IPE4 operate with inputs below ground?
The TLC393IPE4 allows common-mode input voltages down to −0.2 V (with respect to GND) at TA = −40°C to +85°C, provided input current is limited to <5 mA. While brief excursions below ground are tolerated due to internal ESD diodes, sustained sub-ground operation is not recommended. For robust negative-input handling, the TLC393IPE4 should be used with clamping or level-shifting circuitry - and all inputs must remain within −0.2 V to VDD − 1.5 V for guaranteed functionality.
Is the TLC393IPE4 pin-compatible with the LM393?
No, the TLC393IPE4 is not pin-compatible with the LM393. Although both are dual comparators in 8-pin DIP packages, the TLC393IPE4 uses a different pinout: pins 1–4 are OUT1, IN1−, IN1+, GND; pins 5–8 are VDD, OUT2, IN2−, IN2+. In contrast, the LM393 places GND at pin 4 and VDD at pin 8 - requiring PCB layout changes. The TLC393IPE4 also differs in electrical behavior, including lower power, lower input bias current, and LinCMOS process advantages - so direct replacement is not feasible without schematic and layout revision.
