CY74FCT191CTSOC TI Counter IC | 16-SOIC | 4-Bit, Synchronous, Up/Down

Product Overview

The CY74FCT191CTSOC is a high-performance, 4-bit synchronous up/down counter from Texas Instruments. Fabricated with advanced BiCMOS technology, it offers low power consumption and high speed. The device operates from a single 5V supply and is available in a compact 16-SOIC package. It features a fully synchronous operation, with all state changes occurring on the rising edge of the clock. The counter can be preset to any 4-bit value via the parallel load inputs, and it provides both ripple carry and terminal count outputs for cascading multiple stages.
