High speed digital input current limiter

The CLT01-38SQ7 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. Its 6.25 MHz SPI peripheral output serializes the input state transfer to the I/O module controller.
