Description
The 74HC173D,653 is a high-speed, silicon-gate CMOS Quad D-Type Flip-Flop featuring 3-state outputs. It contains four edge-triggered D-type flip-flops with individual data (D) inputs and 3-state buffered outputs. This IC is specifically designed for high-performance bus-oriented systems, providing both synchronous data storage and the ability to disconnect from the data bus when required.
Operating on the positive-going edge of the clock signal, this device features separate active-LOW enable inputs for both the clock and the outputs, offering maximum flexibility in complex digital architectures. As a member of the HC (High-Speed CMOS) logic family, it provides superior noise immunity and low power consumption, making it an ideal choice for modern microcomputer and communication hardware. The SOIC-16 surface-mount package is optimized for high-density PCB layouts.
