Table 2-1. Pin Description

Pin Symbol Function

1 RXD1 Receives data output 1 (open drain)

2 EN1 Enables normal mode 1. When the input is open or low, transceiver 1 is in sleep mode.

3 TXD1 Transmits data input 1, active low output (strong pull-down) after a local wake-up request

4 RXD2 Receives data output 2 (open drain)

5 EN2 Enables normal mode 2. When the input is open or low, transceiver 2 is in sleep mode.

6 WAKE2 High voltage input for local wake-up request. If not needed, connect directly to VS2

7 TXD2 Transmits data input 2, active low output (strong pull-down) after a local wake-up request

8 GND2 Ground 2

9 LIN2 LIN bus line 2 input/output

10 VS2 Battery supply 2

11 INH2 VS2- related high-side switch output for controlling an external load, such as a voltage divider

12 GND1 Ground 1

13 LIN1 LIN bus line 1 input/output

14 VS1 Battery supply 1
