DESCRIPTION

The L603 and L604 are high voltage, high current

darlington arrays each containing eight open col-

lector 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 out-

puts 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.
