Description
The HA16603P is an IC for use with metal proximity switches. It can be used for the coin sensor circuit in vending machines and similar microprocessor sensors.

FEATUREs
● Two proximity switch channels
● The input and output pins are arranged in pairs for convenient printed circuit board mounting.
● Wide operating power-supply voltage range: 4.75 to 30 V
● Low power with a dissipation current of only 2.5 mA
● Normal and inverted outputs can be acquired at the same time.
● The outputs is available for current-source drive only since the internal circuits are NPN transistors with open emitter outputs.
