Description
Serial Clock Input. Data is clocked into the input shift register on the falling edge of the serial
clock input. These devices can accommodate serial input rates of up to 30 MHz.
Positive Analog Supply Voltage.
Serial Data Input. Data is clocked into the 8-bit input register on the falling edge of the serial
clock input.
Ground Reference.
Source. May be an input or output.
Drain. May be an input or output.
Negative Analog Supply Voltage. For single supply operation this should be tied to GND.
Serial Data Output. This allows a number a parts to be daisy chained. Data is clocked out of
the input shift register on the rising edge of SCLK. DOUT is an open-drain output that should be
pulled to the supply with an external pull-up resistor.
Active Low Control Input. Clears the input register and turns all switches to the OFF condition.
Active Low Control Input. This is the frame synchronization signal for the input data. When
SYNC
goes low, it powers on the SCLK and DIN buffers and the input shift register is enabled.
Data is transferred on the falling edges of the following clocks. Taking
SYNC
high updates the
switches.

SDA
Description
Serial Clock Line. This is used in conjunction with the SDA line to clock data into the 8-bit input
shift register. Clock rates of up to 400 kbit/s can be accommodated with this 2-wire serial interface.
Positive Analog Supply Voltage.
Serial Data Line. This is used in conjunction with the SCL line to clock data into the 8-bit input
shift register during the write cycle and used to readback one byte of data during the read cycle. It
is a bidirectional open-drain data line which should be pulled to the supply with an external pull-
up resistor.
Ground Reference.
Source. May be an input or output.
Drain. May be an input or output.
Negative Analog Supply Voltage. For single supply operation this should be tied to GND.
Address Input. Sets the second least signi铿乧ant bit of the 7-bit slave address.
Active Low Control Input. Clears the input register and turns all switches to the OFF condition.
Address Input. Sets the least signi铿乧ant bit of the 7-bit slave address.
