TLC339IN

Comparators Overview

The TLC339IN is a quad, micropower LinCMOS comparator manufactured by Texas Instruments. It features four independent comparators in a 14-PDIP package. The device operates on a single supply voltage ranging from 3V to 16V. Key electrical specifications include a maximum input bias current of 5pA at 5V and a typical output current of 20mA. The static current consumption is maximized at 125µA. Common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) are typically 84dB. The propagation delay is maximized at 4.5µs. Input offset voltage is specified at a maximum of 5mV at 10V. The operating temperature range extends from -40°C to 85°C.
