DESCRIPTION
The Si9241AEY 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_BAT. The transceiver pin is protected and can
be driven beyond the V_BAT voltage.
The Si9241AEY is built on the Vishay Siliconix BiC/DMOS
process. An epitaxial layer prevents latchup.
The RX output is capable of driving CMOS or 1 LSTTL load.
The Si9241AEY is available in a space efficient 8-pin SO
package. It operates reliably over the automotive temperature
range (−40 to 125_C). The Si9241AEY is available in both
standard and lead (Pb)-free packages.
