DESCRIPTION

INH

1 inhibit output for switching external 5 V regulator

TXD

2 transmit data input, when LOW bus data will be dominant, when HIGH bus data will be recessive

RXD

3 receive data output, when LOW bus data will be dominant

NERR

4 error output pin, when LOW a bus error exists

STB

5 not standby digital control input signal (active LOW)

EN

6 enable digital control input signal

WAKE

7 not wake input signal, when pulled down INH becomes active for wake-up (active LOW)

RTH

8 termination resistor, CANH line will be high-impedance with certain bus errors

RTL

9 termination resistor, CANL line will be high-impedance with certain bus errors

VCC

CANH

10 supply voltage (+5 V)

11 high voltage bus line, will be HIGH in dominant state

CANL

12 low voltage bus line, will be LOW in dominant state

GND

13 ground
