DescriptionThe Si9243AEY is a monolithic bus transceiver designed to provide bidirectional serial communication in automotive diagnostic applications.
The Si9243AEY device incorporates protection against overvoltages and short circuits to VBAT. The transceiver pin is protected and can be driven beyond the VBAT voltage.
The RX output is capable of driving CMOS or 1 *LSTTL load.The Si9243AEY is built on the Vishay Siliconix BiC/DMOS process. This process supports bipolar transistors, CMOS, and DMOS. An epitaxial layer prevents latchup.
The Si9243AEY is available in a 8-pin SO package and operates over the automotive temperature range (40 to 125).
