TS372CDT

Overview

The TS372CDT is a low-power dual CMOS voltage comparator manufactured by STMicroelectronics. It features two independent precision comparators designed for single or dual supply operation within a range of 3V to 16V, or ±1.5V to ±8V. The device utilizes silicon gate MOS technology, offering an excellent consumption-speed ratio with very low supply current of 0.1mA per comparator. Key electrical parameters include an extremely low input bias current of 1pA typical, low input offset voltage, and high input impedance of 10^12 ohms typical. It provides fast response time of 200ns typical for TTL level input steps and output compatibility with TTL, MOS, and CMOS logic families.
