STMicroelectronics SCLT3-8BQ7 High-Speed Digital Limiter

STMicroelectronics SCLT3-8BQ7 High-Speed Digital Input Current Limiter provides an 8-line protected digital input termination with serialized state transfer. STMicroelectronics SCLT3-8BQ7 cuts dissipation (78mW per input) and reduces the count of opto-transistors, enhancing the I/O module density. An adjustable digital filter and an LED driver are embedded in each type 3 input section. Its 2MHz SPI peripheral output serializes the input state transfer to the I/O module controller.
