Overview

The TLC3704CN is a quad LinCMOS voltage comparator designed to operate from a single power supply ranging from 3V to 16V. It features push-pull CMOS outputs that are compatible with TTL and CMOS logic, eliminating the need for external pull-up resistors in many designs. With a very low typical quiescent current of 100uA per channel, it is highly efficient for multi-channel monitoring circuits.

Why Choose This Part

The primary advantage is the push-pull output, which provides symmetrical drive capability and simplifies the BOM by removing pull-up resistors. It offers a high Common Mode Rejection Ratio of 84dB and on-chip ESD protection, making it robust for general-purpose industrial and consumer designs.

Applications

Window Comparators
Using multiple channels to monitor if a voltage level stays within a specific upper and lower threshold.
Level Translators
Interfacing between different logic families thanks to the push-pull CMOS output stage and 16V supply capability.
Oscillator Circuits
Building low-power square wave generators or PWM controllers using external RC networks.
Battery Voltage Monitoring
Detecting low-voltage conditions in portable electronics while drawing minimal idle current.

Getting Started

This 14-PDIP package is ideal for breadboard prototyping or through-hole PCB assembly. When designing, ensure the input voltage does not exceed the VDD rail, and decouple the power supply with a 0.1uF ceramic capacitor close to the VDD pin (Pin 4) to minimize noise during output transitions.
