74FR244
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The 74FR244 is a non-inverting octal buffer and line driver
designed to be employed as memory and address driver,
clock driver and bus-oriented transmitter/receiver.
Features
s 3-STATE outputs drive bus lines or buffer memory
address registers
s Outputs sink 64 mA and source 15 mA
s Guaranteed pin-to-pin skew
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
