FACT DATA
Octal Buffer/Line Driver
with 3State Outputs
The MC74AC244/74ACT244 is an octal buffer and line driver designed to be
employed as a memory address driver, clock driver and bus oriented transmitter/
receiver which provides improved PC board density.
• 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
• Outputs Source/Sink 24 mA
• ′ACT244 Has TTL Compatible Inputs
