DARLINGTON ARRAYS
s s s s s s s
EIGHT DARLINGTONS PER PACKAGE OUTPUT CURRENT 400 mA PER DRIVER (500mA PEAK) OUTPUT VOLTAGE 90 V (VCE (sus)) = 70 V) INTEGRAL SUPPRESSION DIODES FOR INDUCTIVE LOADS OUTPUTS CAN BE PARALLELED FOR HIGHER CURRENT TTL / CMOS INPUTS INPUTS PINNED OPPOSITE OUTPUTS TO SIMPLIFY LAYOUT
DIP18 ORDERING NUMBERS: L603C L604C
PIN CONNECTION (top view) DESCRIPTION The L603 and L604 are high voltage, high current darlington arrays each containing 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.
