PIN DESCRIPTIONS
V
CC
–
Power Supply Terminal. This pin acts as the positive rail. The DS1808 will support positive supply
voltages ranging from 5 to 13.2 volts. When V
CC
–V
B
is less than 8 volts the series wiper resistance will
increase up to 1k . The value of V
DD
should never exceed V
CC
.
V
B
–
Substrate Bias Supply. This pin acts as a negative rail. The DS1808 will support negative voltages
ranging from 0 to -13.2 volts. When V
CC
–V
B
is less than 8 volts the series wiper resistance will increase
up to 1k .
V
DD –
DC Supply Terminal. 5V DC voltage supply. The value of V
DD
should never exceed V
CC
.
GND –
Ground Terminal.
SDA –
2-wire
serial data interface. The serial data pin is for serial data transfer to and from the DS1808.
The pin is open drain and may be wire-ORed with other open drain or open collector interfaces.
SCL
– 2-wire serial clock interface. The serial clock input is used to clock data into the DS1808 on rising
edges and clock data out on falling edges.
/CE
– Port Enable Pin. When active (/CE=0), the port inputs SDA and SCL are recognized by the device.
If inactive (/CE=1), the port input pins SDA and SCL are disabled making 2-wire communication
impossible.
