SI9241AEY Product Details


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

 • 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
