Fail-safe Features
• During a short-circuit at LIN to V
• During a short-circuit from LIN to GND the IC can be switched to sleep mode, and even in

• The reverse current is < 2µA at pin LIN during loss of V
• Pin EN provides a pull-down resistor to force the transceiver into sleep mode if EN is
• Pin RXD is set floating if V
• Pin TXD provides a pull-down resistor to provide a static low if TXD is disconnected
• After switching the IC into Normal Mode the TXD pin must be pulled to high longer than
