Each -channel is rated at 400mA and can with stand t(s)peak currents of 500 mA. Suppression diodes are included for inductive load cdriving and the inputs are pinned opposite the outduputs to simplify board layout. roThe four versions interface to all common logic families: te PL603 = 5V TTL leL604 = 6 - 15V CMOS oThese versatile devices are useful for driving a swide range of loads, including solenoids, relays bDC motors, LED displays, filament lamps, thermal Oprintheads and high power buffers.
