74FR2244
Octal Buffer/Line Driver
with 25
Series Resistors in the Outputs
General Description
The
74
FR2244 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
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.
