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
