CD74HC173M – TEXAS INSTRUMENTS

Overview

The Texas Instruments CD74HC173M is a high-speed CMOS D-type flip-flop designed for robust data storage and synchronization in digital systems. Its primary function is to capture and hold data at the rising edge of a clock signal, offering a reliable four-bit storage element. A critical design consideration for this device is the trade-off between its high clock frequency capability (up to 60 MHz) and the potential for increased power consumption and noise sensitivity at the upper limits of its operating voltage range, necessitating careful layout and decoupling strategies in sensitive applications.
