Octal Buffer/Line Driver
with 3-State Outputs
The MC74AC240/74ACT240 is an octal buffer and line driver
designed to be employed as a memory address driver, clock driver and
bus oriented transmitter or receiver which provides improved PC
board density.
Features
• 3−State Outputs Drive Bus Lines or Buffer Memory Address
Registers
• Outputs Source/Sink 24 mA
• ′ACT240 Has TTL Compatible Inputs
• These are Pb−Free Devices
