CD74HC190PWT TI Counter IC | 16-TSSOP | Synchronous, 4-Bit, Up/Down

Product Overview

The CD74HC190PWT is a high-speed synchronous 4-bit up/down counter from Texas Instruments, fabricated using advanced silicon-gate CMOS technology. It features a 16-pin TSSOP package, making it suitable for compact designs. The device operates over a wide voltage range of 2V to 6V and offers high noise immunity and low power consumption. The counter is fully synchronous, with all flip-flops clocked simultaneously on the rising edge of the clock input. It includes a carry look-ahead circuit for cascading multiple stages without external gating.
