Octal Buffer/Line Driver with TRI-STATE
General Description
The ’ABT541 is an octal buffer and line driver with
TRI-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus-oriented transmitter/
receiver. The ’ABT541 is similar to the ’ABT244 with broad-
side pinout.
Features
n Non-inverting buffers
n Output sink capability of 48 mA, source capability of
Ordering Code
