DS75123 Dual Line Driver
General Description
The DS75123 is a monolithic dual line driver designed spe-
cifically to meet the I O interface specifications for IBM Sys-
tem 360 It is compatible with standard TTL logic and supply
voltage levels
The
DS75123 enable driving terminated low impedance lines In
addition the outputs are uncommitted allowing two or more
drivers to drive the same line
Output short-circuit protection is incorporated to turn off the
output when the output voltage drops below approximately
1 5V
