MC74AC573, MC74ACT573
Octal Buffer/Line Driver
with 3-State Outputs
The MC74AC573/74ACT573 is a high−speed octal latch with
buffered common Latch Enable (LE) and buffered common Output
Enable (OE) inputs.
The MC74AC573/74ACT573 is functionally identical to the
MC74AC373/74ACT373 but has inputs and outputs on opposite sides.
Features
Inputs and Outputs on Opposite Sides of Package Allowing Easy
Interface with Microprocessors
Useful as Input or Output Port for Microprocessors
Functionally Identical to MC74AC373/74ACT373
3−State Outputs for Bus Interfacing
Outputs Source/Sink 24 mA
ACT573 Has TTL Compatible Inputs
These are Pb−Free Devices
