CD74HC533E TI Octal D-Type Latch | 20-PDIP | 3-State, 2V-6V

Product Overview

The CD74HC533E from Texas Instruments is a high-speed CMOS octal transparent D-type latch with 3-state outputs. It is designed for use in memory address latching, data storage, and bus-oriented systems. The device features eight latches with individual D-type inputs and common latch enable (LE) and output enable (OE) controls. When LE is high, the outputs follow the inputs; when LE goes low, the data is latched. The 3-state outputs are controlled by OE, allowing connection to a common bus. The CD74HC533E operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. It is offered in a 20-pin PDIP package, providing easy through-hole mounting for prototyping and low-volume production.
