Description

The HD74AC373/HD74ACT373 consists of eight latches with 3-state outputs from bus organized system applications.

The flip-flops appear transparent to the data when Latch Enable (LE) is High. When LE is Low, the data that meets the

setup time is latched. Data appears on the bus when the Output Enable (

OE) is Low. When OE is High, the bus output

is in the high impedance state.

Features

• Eight Latches in a Single Package

• 3-State Outputs for Bus Interfacing

• Outputs Source/Sink 24 mA

• HD74AC373 has TTL-Compatible Inputs
