PIN DESCRIPTION
PIN
SYMBOL
DESCRIPTION
1
ENABLE
Chip enable pin. Grounding this pin puts the
part in a low current (<1
A) mode. It also
disables the rise time accelerators, isolates
SDAIN from SDAOUT and isolates SCLIN
from SCLOUT.
2
SCLOUT
Serial clock output to and from the SCL bus
on the card.
3
SCLIN
Serial clock input to and from the SCL bus
on the backplane.
4
GND
Ground. Connect this pin to a ground plane
for best results.
5
READY
This is an open-drain output which pulls
LOW when SDAIN and SCLIN are
disconnected from SDAOUT and SCLOUT,
and turns off when the two sides are
connected.
6
SDAIN
Serial data input to and from the SDA bus on
the backplane.
7
SDAOUT
Serial data output to and from the SDA bus
on the card.
8
VCC
Power supply.
