DESCRIPTION
The L603 and L604 are high volt age, high current
darlington arrays each c ontaining eight open collector darlington pairs with common emitters. Each
channel is rated at 400mA and can with stand
peak currents of 500 mA.
Suppression diodes are included for inductive load
driving and the inputs are pinned opposite the outputs to simplify board layout.
The four versions interface to all common logic
families:
L603 = 5V TTL
L604 = 6 - 15V CMOS
These versatile devices are useful for driving a
wide range of loads, including solenoids, relays
DC motors, LED displays, filament lamps, thermal
printheads and high power buffers.
