NAME

FUNCTION

1, 3

15, 1

AD0,

AD2

Address Inputs. Select device slave address with AD0 and AD2. Connect AD0 and

AD2 to either GND, V+, SCL, or SDA to give four logic combinations (see Table 3).

216

RST

Reset Input, Active Low. Drive

RST low to clear the 2-wire interface.

4, 5, 11, 12

2, 3, 9, 10

O0, O1,

O6, O7

Output Ports. O0, O1, O6, and O7 are push-pull outputs.

6, 7, 9, 10

4, 5, 7, 8

P2–P5

I/O Ports. P2 to P5 are open-drain I/Os rated to +6V, 20mA.

86

GND

Ground

V+

Positive Supply Voltage. Bypass V+ to GND with a ceramic capacitor of at least

0.047µF as close to the device as possible.
