TLC3704CN
TLC3704CN - Quad Independent Comparator
Overview
The TLC3704CN is a precision quad independent voltage comparator designed for a wide range of analog signal detection and processing applications. This component integrates four high-accuracy comparators in a single 14-pin PDIP (Plastic Dual In-Line Package), making it suitable for space-constrained designs requiring multiple comparison functions. Manufactured using Texas Instruments' advanced LinCMOS™ technology, the TLC3704CN offers low power consumption, high input impedance, and rail-to-rail output swing capability.
This device operates from a single supply voltage ranging from 3V to 16V, or dual supplies of ±1.5V to ±8V, providing flexibility for both battery-powered and line-operated systems. The TLC3704CN features open-drain outputs that can be pulled up to voltages higher than VCC, enabling interface with various logic families and higher voltage systems.
