LM75123
LM75123 is dual line driver manufactured by National Semiconductor.
description
The LM75123 is a monolithic dual line driver designed specifically to meet the I/O interface specifications for IBM System 360. It is patible with standard TIL logic and supply voltage levels.
The low-impedance emitter-follower outputs of the LM75123 enable driving terminated low impedance lines. In addition the outputs are unmited allowing two or more drivers to drive the same line.
Output short-circuit protection is incorporated to tum off the output when, the output voltage drops below approximately 1.5V. features
