DM75493 Datasheet (National Semiconductor)

DM75493, quad LED segment driver

The OM75493 is a quad LED segment driver.

It is designed to interface between MOS IC's and LED's.

An external resistor is required for each segment to drive the output current which is approximately equal to O.7V/RL and is relatively con.tant, independent ot supply variations.
