MC74AC373, MC74ACT373
Octal Transparent Latch
with 3-State Outputs
The MC74AC373/74ACT373 consists of eight latches with 3âstate
outputs for bus organized system applications. The flipâflops 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
⢠3âState Outputs for Bus Interfacing
⢠Outputs Source/Sink 24 mA
⢠â²ACT373 Has TTL Compatible Inputs
⢠These are PbâFree Devices
