SI9243AEY-T1-E3

Product is End of Life 12/2014 Si9243A Vishay Siliconix Single-Ended Bus Transceiver DESCRIPTION FEATURES The Si9243AEY is a monolithic bus transceiver designed to provide bidirectional serial communication in automotive diagnostic applications. • 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 µA at VDD = 0.5 V • Low Quiescent Current in OFF Condition IBAT = 120 µA and IDD ≤ 10 A • ISO 9141 Compatible • Overtemperature Shutdown Function For K Output • Defined K Output OFF for Open GND • Defined Receive Output Status for Open K Input • Defined K Output OFF for TX Input Open • Open Drain Fault Output • 2 kV ESD • Typical Transmit Speeds of 200 kBaud 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). The Si9243AEY is available in both standard and lead (Pb)-free packages.
