Si9243A - Single-Ended Bus Transceiver

General 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 VBAT.

The transceiver pin is protected and can be driven beyond the VBAT voltage.

Key Features

  • Operating Power Supply Range 6 V ≤ VBAT ≤ 36 V.
  • Reverse Battery Protection Down to VBAT ≥ - 24 V.
  • Standby Mode With Very Low Current Consumption IBAT(SB) = 1.

Product is End of Life 12/2014 Single-Ended Bus Transceiver Si9243A Vishay Siliconix 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 VBAT. The transceiver pin is protected and can be driven beyond the VBAT voltage. The RX output is capable of driving CMOS or 1 x 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 °C to 125 °C).
