PINNING

SYMBOL PIN

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)
