DESCRIPTION

The L9703isa bipolar monolithic integratedcir cuit for monitoring the status of up to eight contacts connected to GND.

It contains eight contact senseinputs and eight microcomputer compatible three-state outputs.

. OPERATING DC SUPPLY VOLTAGE RANGE 5V TO 25V

. SUPPLY OVERVOLTAGEPULSE UP TO 40V

. VERY LOW STANDBY QUIESCENT CURRENT 0.2mA

. INTERNAL CLAMPING DIODES AT CONTACT INPUTS TO VS AND GND

. INPUT PULSE CURRENT CAPABILITY UP TO + 50mA ; – 75mA

. NOMINAL CONTACT CURRENT OF 10mA DEFINED BY EXTERNAL CONTACT SERIES RESISTORS RI N1–8

. CONTACT STATUS MONITORING BY COMPARING THE RESISTANCE AT CONTACT SENSEINPUTS WITHTHE INTERNAL REFERENCE RESISTOR VALUE

. HIGHIMMUNITY DUE TO RESISTANCE COMPARISON WITH HYSTERESIS
