iC-VRV
BIDIRECTIONAL µP INTERFACE TO 24V
FEATURES
Ë 2 × 4 bidirectional input/output stages at 24 V
Ë Input/output mode programmable for each 4 bits
Ë Guaranteed low-side driving capability of 100 mAdc and
500 mApeak for pulse load
Ë Short-circuit-proof driver with high electric strength
up to 48 V
Ë Low saturation voltage of 0.4 V at 10 mA and
1.5 V at 500 mA
Ë Programmable pull-down current sources
Ë Built-in free-wheeling diodes with externally accessible
common cathode
Ë Flashing function for the outputs
Ë Programmable digital input filters with externally adjusted
filtering times
Ë Bus capability via high-speed microprocessor interface
Ë Programmable interrupt output
Ë Shutdown at overtemperature and low voltage
