DESCRIPTION
The Si9243AEY is a monolithic bus transceiver designed to
provide bidirectional serial communication in automotive
diagnostic applications.
The device incorporates protection against overvoltages and
short circuits to V
driven beyond the V
The RX output is capable of driving CMOS or 1

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_C). The Si9243AEY is available in both standard and
lead (Pb)-free packages.
