Product Overview
The CD74HCT373M96 is a high-speed CMOS octal transparent latch with 3-state outputs from Texas Instruments. It is designed for use in memory address latching, data storage, and bus driving applications. The device operates from a 4.5V to 5.5V supply voltage and features eight D-type latches with common latch enable (LE) and output enable (OE) controls. When LE is high, the outputs follow the data inputs; when LE goes low, the data is latched. The 3-state outputs allow connection to a common bus.
