FEATURES y y y y y y y y y Supply voltage range VDD 4.75V to 5.25V Monitoring supply voltage range VS 5.25V to 25V Maximum overvoltage protection up to 40V Internal clamp diodes at each input to VS and GND Low standby current ( typical < 10A ) Contact status monitoring by comparison of the resistance at the inputs with an internal reference High noise immunity - 40C to + 125C operating temperature SO20w package The output switches to high when the input resistance increases to above 9kY and switches to low when the input resistance falls below 1.5kY. These values are valid within the supply range 5.25V APPLICATION y y y Automotive electronics Monitor for mechanical switches Monitor for voltage levels A closed switch corresponds to a low logic level on the outputs OUT0-7. to 25V. The input currents are compared with the current of an internal reference resistor. The IC is designed to operate with an external series resistor RIN0 to RIN7 of 1kY. The current, driven through the contacts keeps their resistance low. DESCRIPTION The IC monitors the status of all switch contacts connected to ground continuously .
