74FR2244
Octal Buffer/Line Driver
with 25Series Resistors in the Outputs
General Description
The 74FR2244 is a non-inverting octal buffer and line driver
designed to drive capacitive inputs of MOS memory
devices, address and clock lines or act as a low under-
shoot general purpose bus driver.
Features
s 3-STATE outputs drive bus lines or buffer memory
address registers
s Outputs sink 12 mA and source 15 mA
s 25series resistors in outputs eliminate the need for
external resistors
s Designed to drive the capacitive inputs of MOS devices
