8ch Darlington Sink Driver

The ULN2803APG / AFWG Series are high−voltage, high−current darlington drivers comprised of eight NPN darlington pairs.

All units feature integral clamp diodes for switching inductive loads.

Applications include relay, hammer, lamp and display (LED) drivers.

The suffix (G) appended to the part number represents a Lead (Pb)-Free product.

Features

Output current (single output) 500 mA (Max.)

High sustaining voltage output 50 V (Min.)

Output clamp diodes

Inputs compatible with various types of logic.

Package Type−APG	: DIP−18pin
