Description
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.
