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 high-

power-demand devices.

The SN75436 and SN75437A are offered in a

16-pin wide-body surface-mount (NE) package

and is characterized for operation over the free-air

temperature of 0

°C to 70°C.
