DUAL_LAMP_DRIVER

National DS75451 dual peripheral AND driver using positive logic provides up to 300 mA per section for driving incandescent lamps. Optional keep-alive resistors R maintain OFF-state lamp current at about 10% of rated value to reduce surge current.Lamp voltage depends on lamps used. Relays shown, with diodes across solenoids, can be used in place of lamps if desired.- Interface Databook, National Semiconductor, Santa Clara, CA, 1978, p 3-20-3-30.
