8-Channel Darlington Current Driver TD62783A FEATURES • • • • • • • 8 Darlington Arrays per Package Minus 500 mA (Source) Output Current (Single Output) Output voltage 50V Output Clamp Diodes Input Compatible with Various Types of Logic Relay-Driver Applications Input pins placed opposite to output pins to simplify layout SOP-18 APPLICATION • • • • • • Relay Drivers Stepper and DC Brushed Motor Drivers Lamp Drivers Display Drivers Line Drivers Logic Buffers DIP-18 ORDERING INFORMATION DESCRIPTION The TD62783A is monolithic high-voltage, high-current Darlington transistor arrays. Each consists of eight NPN Darlington pairs that feature high-voltage outputs with common-anode clamp diodes for switching inductive loads. The collector-current rating of a single Darlington pair is minus 500 mA. The Darlington pairs may be paralleled for higher current capability. Applications include relay drivers, hammer drivers, lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers.
