SCLT3 High speed digital input current limiter

The STM-SCLT3-8BQ7 provides an 8-line protected digital input termination with serialized state transfer. This device enhances the I/O module density by cutting the dissipation (78 mW per input) and reducing the count of opto-transistors. An adjustable digital filter and an LED driver are embedded in each type 3 input section. Its 2 MHz SPI peripheral output serializes the input state transfer to the I/O module controller. 8 inputs - 8-bit SPI output High side input with common ground 5 V Voltage regulator Package: QFN 7x7 - 48L 30 V reverse polarity capable Adjustable current limiters LED output for visual status Optional: 16-bit mode with parity check, temperature and voltage alarms Daisy chain capable Input digital filter with adjustable delay: 20 µs to 3 ms Power dissipation: 78 mW per channel
