CD74HC190PWR TI Counter IC | 16-TSSOP | 2V-6V, Synchronous Up/Down

Product Overview

The CD74HC190PWR is a high-speed synchronous up/down counter from Texas Instruments, fabricated with silicon-gate CMOS technology. It operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. The device features a 4-bit binary counter with parallel load capability, asynchronous reset, and ripple clock output for cascading multiple stages. Packaged in a compact 16-TSSOP, it is ideal for space-constrained designs.
