Product details
Overview
TLC393CPS from Texas Instruments is a dual micropower voltage comparator in SOIC-8 package, 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 open-drain CMOS outputs-enabling use in battery-powered sensor threshold detection and low-voltage power supervision circuits.
For engineers reviewing the TLC393CPS datasheet, TLC393CPS pinout, TLC393CPS application, or TLC393CPS equivalent, key selection considerations include its commercial-grade temperature range (0°C to 70°C), 5 mV max input offset voltage, LinCMOS™ process-enabled high input impedance (>1012 Ω), and compatibility with pull-up loads up to 16 V.
Technical Context
The TLC393CPS integrates two independent comparators on a single die using Texas Instruments' LinCMOS™ process, delivering ultra-low quiescent current without sacrificing speed. Its open-drain output stage requires external pull-up resistors and supports mixed-voltage interfacing-e.g., 5-V logic driving 12-V loads.
Input common-mode range extends from −0.2 V to (VDD − 1.5) V across 0°C to 70°C, and ESD protection meets MIL-STD-883C Method 3015.2 (2000 V HBM). The device avoids linear-region stress via digital output architecture, eliminating need for servo-loop testing during characterization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 3 V to 16 V - supports wide-input industrial and automotive auxiliary rails without regulation |
| Quiescent supply current | 22–50 µA (both comparators, 0°C to 70°C) - enables multi-year operation on coin cells |
| Propagation delay (tPLH) | 2.5 µs typ @ 5-mV overdrive, VDD = 5 V - sufficient for 100-kHz PWM feedback and supply fault detection |
| Input offset voltage | 6.5 mV max (0°C to 70°C) - ensures reliable thresholding within ±3% of reference voltage |
| Input bias current | 0.6 nA max @ 70°C - minimizes error in high-impedance sensor interfaces (e.g., thermistors, photodiodes) |
| Output configuration | Open-drain CMOS - allows wired-OR logic, level translation, and direct interface to LEDs or MOSFET gates |
| Common-mode input range | 0 V to (VDD − 1.5) V - accommodates rail-to-rail sensing with headroom for internal circuitry |

| 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 - accepts voltages from −0.2 V to (VDD − 1.5) V |
| 3 | IN1+ | Non-inverting input of comparator 1 - same voltage range as IN1− |
| 4 | GND | Analog ground reference - must be low-impedance return path for stable comparison |
| 5 | VDD | Positive supply rail - powers both comparators and internal ESD structures |
| 6 | OUT2 | Open-drain output of comparator 2 - independently controllable; shares no internal nodes with OUT1 |
| 7 | IN2− | Inverting input of comparator 2 - electrically isolated from IN1− |
| 8 | IN2+ | Non-inverting input of comparator 2 - fully independent channel with identical specs to comparator 1 |

Use Scenario: Providing early power-fail warning and reset assertion for microcontrollers during brownout conditions. IC Role / Device Role / Timing Role: First comparator monitors 5-V rail; second monitors 12-V rail - both feed OR'd interrupt line. Use Value: 5-mV max offset guarantees accurate trip point within ±0.1% of reference divider network. |
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), slower tPLH (1.5 µs min but higher variance), no LinCMOS™ input stability | Suitable for cost-sensitive, non-battery applications where 50× higher power is acceptable | Select LM393DR only if legacy footprint compatibility is required and power budget >100 µA |
| TLC3702CDR | Push-pull outputs (no external pull-up needed), 10× higher supply current (500 µA), same LinCMOS™ input performance | Better for driving capacitive loads directly or interfacing with CMOS logic without pull-ups | Choose TLC3702CDR when output drive strength and elimination of external components outweigh power savings |
Compared with LM393DR and TLC3702CDR, the TLC393CPS uniquely balances ultra-low power (22 µA), fast response (2.5 µs), and robust input characteristics - making it optimal for energy-constrained, precision threshold-detection systems where open-drain flexibility is acceptable.

FAQ
What is the maximum supply voltage rating for the TLC393CPS?
The absolute maximum supply voltage for the TLC393CPS is 18 V, though recommended operation is limited to 3 V to 16 V. Exceeding 18 V risks permanent damage to the internal ESD protection diodes and LinCMOS™ input structure. Operation at 16 V is validated across the full 0°C to 70°C commercial temperature range, with supply current remaining within 50 µA.
Does the TLC393CPS support rail-to-rail input operation?
The TLC393CPS does not support true rail-to-rail input: its common-mode input voltage range is specified as −0.2 V to (VDD − 1.5) V at 0°C to 70°C. At VDD = 5 V, this means inputs must stay between −0.2 V and 3.5 V for guaranteed operation. Inputs beyond this range may forward-bias internal ESD diodes, requiring current limiting to <5 mA to prevent damage.
Can the TLC393CPS drive an LED directly?
Yes - the TLC393CPS open-drain outputs can sink up to 20 mA each, enabling direct LED drive when configured with a series resistor and VDD-referenced anode. For example, with VDD = 5 V and a red LED (VF ≈ 1.8 V), a 150-Ω resistor limits current to ~21 mA. Ensure thermal derating is applied if both outputs operate continuously at full load.
What is the input offset voltage drift over temperature for the TLC393CPS?
The TLC393CPS has a maximum input offset voltage of 6.5 mV across 0°C to 70°C, with typical drift less than 0.5 µV/°C. The LinCMOS™ process ensures minimal offset variation under differential stress, and Figure 4 in the datasheet shows a Gaussian distribution centered near 1.4 mV at 25°C - indicating tight parametric consistency across production lots.
Is the TLC393CPS pin-compatible with the LM393?
No - while functionally similar, the TLC393CPS and LM393 have identical pinouts *only* in SOIC-8 (D) and PDIP-8 (P) packages. However, the TLC393CPS PS suffix denotes SOIC-8, matching LM393DR's pin assignment: Pin 1 (OUT1), Pin 2 (IN1−), Pin 3 (IN1+), Pin 4 (GND), Pin 5 (VDD), Pin 6 (OUT2), Pin 7 (IN2−), Pin 8 (IN2+). Electrical differences (e.g., 20× lower supply current) require validation in final circuit design.
