74F2240
Octal Buffer/Line Driver
with 25Ω Series Resistors in the Outputs
General Description
The 74F2240 is an 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.
The 25Ω series resistor in the outputs reduces undershoot
and ringing and eliminates the need for external resistors.
Features

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
s
Guaranteed 4000V minimum ESD protection
