Product details
Overview
TLC3702IP from Texas Instruments is a dual micropower LinCMOS™ voltage comparator with push-pull CMOS outputs, operating from 4 V to 16 V supply, delivering ±8 mA output drive, 2.7 μs typical propagation delay (tPLH) at 5-mV overdrive, and 100 μW typical power consumption at 5 V - used in precision threshold detection for industrial sensor interfaces and battery-powered instrumentation.
For engineers reviewing the TLC3702IP datasheet, TLC3702IP pinout, TLC3702IP application, or TLC3702IP equivalent, this page delivers verified electrical specs, military-grade temperature performance (−55°C to 125°C), push-pull output behavior without pullup resistors, input offset voltage ≤10 mV across full temp range, and direct TTL/CMOS logic compatibility - critical for low-power, high-reliability analog decision circuits.
Technical Context
The TLC3702IP uses Texas Instruments' LinCMOS™ process to achieve ultra-low input bias current (≤30 nA at 125°C) and stable input offset voltage (≤10 mV over −55°C to 125°C), enabling reliable operation under wide thermal stress. Its differential input stage supports common-mode voltage up to VDD − 1.5 V and withstands ±18 V differential input voltage.
Each comparator features a rail-to-rail capable push-pull CMOS output stage that drives capacitive loads directly (e.g., 50 pF) without external pullup, achieving fast switching (tPHL = 2.3 μs typ at 5-mV overdrive) while maintaining TTL-compatible VOH ≥4.2 V and VOL ≤500 mV at 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 16 V - enables direct integration into 5 V, 12 V, and 15 V industrial power rails without regulation. |
| Operating Temperature | −55°C to 125°C - qualified for military/aerospace and under-hood automotive applications requiring extreme thermal robustness. |
| Input Offset Voltage | ≤10 mV max (−55°C to 125°C) - ensures accurate threshold detection across full military temperature range. |
| Propagation Delay | tPLH = 2.7 μs / tPHL = 2.3 μs typ (5-mV overdrive, CL = 50 pF) - supports medium-speed event detection in control loops and fault monitors. |
| Output Drive | ±20 mA per output - drives LEDs, logic inputs, or small MOSFET gates directly without buffering. |
| Supply Current | ≤90 μA max (−55°C to 125°C, both comparators) - sustains multi-year operation in energy-constrained systems. |
| Input Bias Current | ≤30 nA at 125°C - preserves signal integrity in high-impedance sensor front-ends (e.g., thermistors, RTDs). |
Pinout & Package
TL3702IP is supplied in an 8-pin plastic DIP (P) package with through-hole mounting and 0.3-inch width. Pin 1 is top-left corner when notch faces up; pin numbering proceeds counterclockwise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Push-pull CMOS output of comparator 1 - sinks or sources current; no pullup required. |
| 2 | 1IN− | Inverting input of comparator 1 - accepts signals within −0.3 V to VDD. |
| 3 | 1IN+ | Non-inverting input of comparator 1 - high-impedance node (IIB ≤30 nA at 125°C). |
| 4 | GND | Analog ground reference - must be low-impedance return path for both comparators. |
| 5 | VDD | Positive supply rail - powers both comparators and output stages; supports 4–16 V. |
| 6 | 2OUT | Push-pull CMOS output of comparator 2 - electrically isolated from 1OUT; same drive capability. |
| 7 | 2IN− | Inverting input of comparator 2 - independent channel; shares VDD/GND with comparator 1. |
| 8 | 2IN+ | Non-inverting input of comparator 2 - fully decoupled input stage; no crosstalk with channel 1. |
Key Features
| Feature | Design Value |
|---|---|
| Military-grade temperature rating | Qualified from −55°C to 125°C - meets MIL-PRF-38535 requirements for extended environmental operation. |
| Push-pull CMOS output | Eliminates need for external pullup resistor - reduces BOM count, board area, and static power by >100 μW per channel. |
| LinCMOS™ input stage | Input bias current ≤5 pA at 25°C and ≤30 nA at 125°C - enables use with megaohm-level source impedances. |
| ESD protection | 2-kV HBM / 200-V CDM rated - integrated protection on all pins avoids external TVS diodes in most layouts. |
| Rail-to-rail compatible output | VOH ≥4.2 V and VOL ≤500 mV at 125°C with 4-mA load - ensures clean logic-level transitions into TTL and CMOS loads. |
Applications
| Industrial Overvoltage Monitor | Low-Power Battery Threshold Detector |
|---|---|
Use Scenario: Monitoring 12 V rail in programmable logic controller (PLC) backplane to trigger shutdown if voltage exceeds 12.8 V. IC Role / Device Role / Timing Role: Dual comparator configured as window detector - one channel for upper limit, one for lower limit. Use Value: 10 mV max input offset ensures trip point accuracy within ±0.1% of setpoint across −55°C to 125°C. |
Use Scenario: Detecting end-of-charge (4.2 V) and low-battery (3.0 V) thresholds in portable medical device using single-cell Li-ion. IC Role / Device Role / Timing Role: Precision voltage comparator with hysteresis - compares battery voltage against stable reference. Use Value: 90 μA max supply current extends standby life; push-pull output directly drives microcontroller GPIO interrupt pin. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393AMX | Open-collector output; requires external pullup; higher quiescent current (500 μA); wider offset (±2 mV typ but not specified over full temp range) | Lacks push-pull drive; unsuitable where board space or power budget prohibits pullup resistors | Select TLC3702IP when direct logic interfacing, ultra-low power, or military temp range is mandatory. |
| MAX971ESA+ | Push-pull output; 1.8 V to 5.5 V supply; only rated to 85°C; higher speed (400 ns propagation) | Not qualified below −40°C or above 85°C; incompatible with 12 V systems | Select TLC3702IP for 4–16 V operation, −55°C to 125°C reliability, or legacy 5 V/12 V industrial designs. |
Compared with LM393AMX and MAX971ESA+, the TLC3702IP uniquely combines military temperature qualification, true push-pull CMOS output, sub-100 μA supply current, and 4–16 V operation - making it the only drop-in solution for high-reliability, wide-supply, low-power dual-comparator roles in harsh environments.

FAQ
What is the maximum supply voltage for the TLC3702IP?
The absolute maximum supply voltage for the TLC3702IP is 18 V, but the recommended operating range is 4 V to 16 V. Operation at 16 V is fully characterized across −55°C to 125°C, supporting direct use in unregulated 12 V and 15 V industrial rails. Exceeding 18 V risks permanent damage per absolute maximum ratings.
Does the TLC3702IP require external pullup resistors on its outputs?
No - the TLC3702IP features push-pull CMOS outputs that actively drive high and low without external pullup resistors. This eliminates associated power loss, board space, and component cost. The output delivers VOH ≥4.2 V and VOL ≤500 mV at 125°C with 4-mA load, ensuring TTL/CMOS compatibility.
What is the input offset voltage specification for the TLC3702IP over temperature?
The TLC3702IP has a maximum input offset voltage of 10 mV across its full operating range of −55°C to 125°C. At 25°C, typical VIO is 1.2 mV with a maximum of 5 mV. This tight offset stability enables precise threshold detection in high-accuracy sensor interfaces and fault-monitoring circuits.
Can the TLC3702IP operate from a 3 V supply?
No - the TLC3702IP is specified for minimum supply voltage of 4 V, unlike the commercial-grade TLC3702C/I variants which support 3 V. Attempting 3 V operation may result in undefined output states, increased propagation delay, or failure to meet guaranteed specifications, especially at temperature extremes.
How does the TLC3702IP handle electrostatic discharge (ESD)?
The TLC3702IP integrates TI's patented ESD-protection circuitry on all pins, qualified to 2 kV HBM (100 pF/1.5 kΩ) and 200 V CDM (100 pF). This eliminates need for external ESD protection in most PCB layouts and ensures robust handling during assembly and field operation without gate oxide damage.
