description

The

SN75476

through

SN75478

are

dual

peripheral drivers designed for use in systems that

require high current, high voltage, and fast

switching times. The SN75476, SN75477, and

SN75478 provide AND, NAND, and OR drivers

respectively. These devices have diode-clamped

inputs as well as high-current, high-voltage clamp

diodes on the outputs for inductive transient

protection.

The SN75476, SN75477, and SN75478 drivers

are characterized for operation from 0

°C to 70°C.
