High-speed 8-line digital input current limiter with serialized state transfer

Mouser now stocks the STMicroelectronics CLT01-38SQ7 high-speed digital input current limiter which provides an 8-line protected digital input termination with serialized state transfer. The CLT01-38SQ7 cuts dissipation (78mW per input) and reduces the count of opto-transistors, enhancing I/O module density. Its 6.25MHz SPI peripheral output serializes the input state transfer to the I/O module controller. Applications for the EN60947-5-2 compliant devices include programmable logic controller and remote input modules, high speed protected termination for digital input with serialized SPI output, and IEC61131-2 type 1, 2 and 3 systems.
