74HC173 4-Bit D-Type Register with 3-State Output IC - DIP-16 Package

The 74HC173 is a high-speed CMOS 4-bit D-type register featuring 3-state outputs. It incorporates both clock and enable inputs for synchronous data storage and output control. The device includes four D-type flip-flops with a common clock and asynchronous clear function. It also features two output enable inputs that allow the output to be either active or in the high-impedance state, making it suitable for bus-oriented systems.

This IC is widely used in microprocessor and memory interfacing applications where temporary data storage with controlled output is required.

Features of 74HC173 4-Bit Register IC:

1. 4-bit D-type register with 3-state output
