Octal Transparent Latch
with 3State Outputs
The MC74AC373/74ACT373 consists of eight latches with 3state
outputs for bus organized system applications. The flipflops 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
3State Outputs for Bus Interfacing
Outputs Source/Sink 24 mA
′ACT373 Has TTL Compatible Inputs
PbFree Packages are Available
