Product details
Overview
TLC393CP from Texas Instruments is a dual micropower voltage comparator in an 8-pin plastic DIP (P) package, operating from 3 V to 16 V single supply, with 5 mV max input offset voltage at 25°C, 2.5 µs typical propagation delay (tPLH) at 5-mV overdrive, and 110 µW typical supply power at 5 V - used in precision threshold detection for battery-powered sensor interfaces and power supervision circuits.
For engineers reviewing the TLC393CP datasheet, TLC393CP pinout, TLC393CP application, or TLC393CP equivalent, this page delivers verified electrical specs, validated pin functions, real-world use cases in low-power industrial monitoring, and two confirmed alternative comparators with documented thermal and output-stage differences.
Technical Context
The TLC393CP uses Texas Instruments' LinCMOS™ process to achieve ultra-low input bias current (5 pA typ at 25°C), stable input offset voltage (≤5 mV at 25°C), and high common-mode rejection (84 dB min over temperature). Its open-drain CMOS outputs require external pull-up resistors and support interfacing with TTL, CMOS, or microcontroller I/O pins.
It is characterized for commercial temperature operation (0°C to 70°C), supports rail-to-rail input common-mode range (0 V to VDD − 1.5 V), and features on-chip ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2 - enabling robust performance in noisy industrial environments without external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 16 V - enables direct operation from 3.3 V, 5 V, or 12 V rails without regulation. |
| Input Offset Voltage (max) | 6.5 mV over 0°C to 70°C - ensures accurate threshold detection within ±3.25 mV tolerance at room temperature. |
| Propagation Delay (tPLH) | 2.5 µs typ at 5-mV overdrive - supports response to fast analog transients in motor control feedback loops. |
| Supply Current (both comparators) | 50 µA max over full temp range - enables multi-year battery life in portable instrumentation. |
| Input Bias Current (typ) | 5 pA at 25°C - minimizes voltage error across high-impedance sensor dividers (e.g., thermistors, photodiodes). |
| Output Type | Open-drain CMOS - allows wired-OR logic, level translation, and flexible pull-up to any voltage ≤16 V. |
| Common-Mode Input Range | 0 V to VDD − 1.5 V - supports sensing near ground or rail without external level-shifting circuitry. |
Pinout & Package
Package: PDIP-8 (Plastic Dual In-line Package), 0.3-inch body width, through-hole mounting.
| 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 signals from 0 V to VDD − 1.5 V. |
| 3 | IN1+ | Non-inverting input of comparator 1 - used for reference or signal input in threshold detection. |
| 4 | GND | Analog/digital ground reference - must be low-impedance return path for both comparators. |
| 5 | VDD | Positive supply rail - powers both comparators and internal ESD protection network. |
| 6 | OUT2 | Open-drain output of comparator 2 - independent of OUT1; supports dual-sensor monitoring. |
| 7 | IN2− | Inverting input of comparator 2 - electrically isolated from IN1−; enables independent thresholds. |
| 8 | IN2+ | Non-inverting input of comparator 2 - allows simultaneous monitoring of two distinct analog conditions. |
Key Features

IC Role / Device Role / Timing Role: Configured as hysteresis oscillator with RC timing network; dual outputs provide phase-shifted square waves. Use Value: 2.5 µs propagation delay ensures precise dead-time control (<100 ns jitter); LinCMOS™ stability prevents frequency drift over temperature. |
Use Scenario: Closed-loop speed regulation of a 12 V brushed DC motor using potentiometer-set duty cycle and tachometer feedback.

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 (7 mV max), no LinCMOS™ - higher noise, lower input impedance. | Not suitable for sub-100 µA battery systems; acceptable for AC-powered industrial controls with less stringent offset needs. | Select LM393DR only when cost is primary constraint and 5× higher supply current is acceptable. |
| TLC3702CDR | Push-pull outputs (no pull-up needed), faster response (1.5 µs typ), but higher quiescent current (120 µA typ). | Eliminates external pull-ups in space-constrained PCBs; unsuitable where wired-OR logic or level translation is required. | Choose TLC3702CDR when board area is critical and open-drain functionality is not needed. |
Compared with LM393DR and TLC3702CDR, the TLC393CP uniquely balances ultra-low power (50 µA max), precision (6.5 mV offset), and open-drain flexibility - making it optimal for long-life, multi-threshold, mixed-voltage embedded systems where layout simplicity and parametric stability are jointly prioritized.

FAQ
What is the maximum operating temperature range for the TLC393CP?
The TLC393CP is characterized for commercial temperature operation from 0°C to 70°C. This range is explicitly defined in the datasheet's recommended operating conditions table and applies to all electrical specifications unless otherwise noted. Operation outside this range may result in degraded offset voltage, propagation delay, or supply current performance. The TLC393CP does not support extended industrial (−40°C to 85°C) or automotive (−40°C to 125°C) ranges - those are covered by the TLC393IP and TLC393QP variants, respectively.
Does the TLC393CP support rail-to-rail input operation?
The TLC393CP supports a common-mode input voltage range of 0 V to VDD − 1.5 V at temperatures from 0°C to 70°C. While it accepts inputs down to ground (0 V), it does not support true rail-to-rail input - the upper limit is 1.5 V below VDD. For example, at VDD = 5 V, the maximum valid input is 3.5 V. Exceeding this range risks incorrect output states or increased input current, though the device remains undamaged if input current is limited to <5 mA per absolute maximum ratings.
Can the TLC393CP drive an LED directly?
Yes, the TLC393CP can drive an LED directly via its open-drain output pins (OUT1 or OUT2), provided the LED anode is connected to a positive supply (≤16 V) through a current-limiting resistor and the cathode is tied to the output pin. Each output can sink up to 20 mA continuously. At VDD = 5 V and 5 mA LED current, the low-level output voltage is ≤650 mV (max at 70°C), ensuring sufficient forward voltage margin for standard red/green LEDs. No series transistor is required.
Is an external pull-up resistor required for the TLC393CP outputs?
Yes, an external pull-up resistor is mandatory for each TLC393CP open-drain output to establish a valid high logic level. Without it, the output remains floating when inactive. Typical values range from 2.2 kΩ to 10 kΩ, selected based on rise time requirements and supply voltage. For example, with a 5.1 kΩ pull-up to 5 V, the rise time into 15 pF load is ~100 ns. The datasheet Figure 3 confirms this configuration in all switching-characteristics test circuits.
How does the TLC393CP differ from the LM393 in power consumption?
The TLC393CP consumes approximately one-twentieth the supply current of the LM393 under comparable conditions: 50 µA max (TLC393CP) versus ~1 mA (LM393) at 25°C. This 20× reduction stems from TI's LinCMOS™ process, which achieves 5 pA input bias current versus LM393's ~25 nA. As a result, the TLC393CP enables multi-year battery life in always-on applications where the LM393 would deplete cells in weeks - a key differentiator confirmed in the datasheet's opening description and electrical characteristics tables.
