74F2244
Octal Buffer/Line Driver
with 25Series Resistors in Outputs
General Description
The F2244 is an octal buffer/line driver designed to drive
the capacitive inputs of MOS memory drivers, address driv-
ers, clock drivers and bus-oriented transmitters/receivers.
The 25series resistors in the outputs reduce ringing and
eliminate the need for external resistors.
Features
s 3-STATE outputs drive bus lines or buffer memory
address registers
s 12 mA source current
s 25series resistors in outputs eliminate the need for
external resistors.
s Designed to drive the capacitive inputs of MOS devices
s Guaranteed 4000V minimum ESD protection
