74FR2240
Octal Buffer/Line Driver
with 25
Series Resistors in the Outputs
General Description
The
74
FR2240 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.
Features
I
3-STATE outputs drive bus lines or buffer memory
address registers
I
Outputs sink 12 mA and source 15 mA
I
25
series resistors in outputs eliminate the need for
external resistors
I
Designed to drive the capacitive inputs of MOS devices
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
