Overview

The TLC3704IDR is a quad micropower LinCMOS voltage comparator designed to operate from a single power supply ranging from 3V to 16V. It features a push-pull CMOS output stage capable of driving TTL and CMOS loads directly without the need for external pull-up resistors. This device is particularly efficient for portable or battery-powered systems due to its extremely low typical supply current of 125uA per comparator.

Why Choose This Part

The primary advantage is the combination of a push-pull output and ultra-low power consumption, eliminating the static current draw associated with open-collector pull-up resistors. It provides a high Common-Mode Rejection Ratio (CMRR) of 84dB and can handle input voltages up to 16V, offering significant headroom for industrial and automotive-grade rail monitoring.

Applications

Pulse-Width-Modulated Motor Speed Controller
Utilizes the four independent comparator elements to generate PWM signals for controlling motor velocity.
Enhanced Supply Supervisor
Monitors multiple voltage rails simultaneously to trigger system resets or alerts during under-voltage conditions.
Micropower Switching Regulator
Serves as the control element in low-current DC-DC converters where high efficiency and low standby power are critical.
Two-Phase Nonoverlapping Clock Generator
Uses the fast response times and precise thresholds to create timing signals for switched-capacitor circuits.

Getting Started

To evaluate this part, prototype using a 14-SOIC to DIP adapter on a breadboard or integrated into a custom PCB. Ensure that a 0.1uF ceramic bypass capacitor is placed as close as possible to the VDD pin to maintain stability during high-speed output transitions.
