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.
