74FR2244
Octal Buffer/Line Driver
with 25Ω Series 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
25Ω series resistors in outputs eliminate the need for
external resistors
s
Designed to drive the capacitive inputs of MOS devices
