CD74HCT373E-NG TI Octal D-Type Latch | 20-PDIP | 4.5V-5.5V, 8mA Output

Product Overview

The CD74HCT373E-NG is a high-speed CMOS octal transparent latch with 3-state outputs from Texas Instruments. It is designed for use in memory address latching, I/O port expansion, and bus-oriented systems. The device features eight D-type latches with a common latch enable (LE) and output enable (OE) control. When LE is high, the Q outputs follow the D inputs; when LE goes low, the data is latched. The OE input controls the 3-state outputs, allowing connection to a common bus. The CD74HCT373E-NG is pin-compatible with the LS373 and operates over a wide voltage range of 4.5V to 5.5V, making it suitable for interfacing with TTL logic levels.
