description

The SN75436 and SN75437A quadruple
peripheral drivers are designed for use in systems
requiring high current, high voltage, and high load
power. Each device features four inverting
open-collector outputs with a common-enable
input that, when taken low, disables all four
outputs. The envelope of 1-V characteristics
exceeds the specifications sufficiently to avoid
high-current latch-up. Applications include driving
relays, lamps, solenoids, motors, LEDs,
transmission lines, hammers, and other high­power-demand devices.
