Shunt Input to Crosspoint B. Use for shunt capacitor or AC ground connection to
improve off-isolation, or as an additional input to switch matrix B.
Input 3 to Crosspoint A
Input 3 to Crosspoint B
High Side of Bias Network. Use to give the outputs a DC bias when inputs are
AC-coupled (refer to the Using the Internal Bias Resistors section).
Low Side of Bias Network. Use to give the outputs a DC bias when inputs are
AC-coupled (refer to the Using the Internal Bias Resistors section).
Input 4 to Crosspoint A
Input 4 to Crosspoint B
Positive Supply Voltage. Supply range is +2.7V to +5.25V. Connect pin 8 to pin 24 exter-
nally.
Output 2 of Crosspoint A
Auxiliary Output 0
Output 2 of Crosspoint B
Auxiliary Output 1
LSB+1 of 2-Wire Serial-Interface Address Field
Chip Select of 3-Wire Interface. Logic low on CS enables serial data to be clocked in to
device. Programming commands are executed on CS’s rising edge.
2-Wire Serial-Interface Clock Input
3-Wire Serial-Interface Clock Input
2-Wire Serial-Interface Data Input. Data is clocked in on SCL’s rising edge.
3-Wire Serial-Interface Data Input. Data is clocked in on SCLK’s rising edge.
LSB+2 of 2-Wire Serial-Interface Address Field
Data Output of 3-Wire Interface. Input data is clocked out and SCLK’s falling edge
delayed by 16 clock cycles. DOUT remains active when CS is high.

Input 1 to Crosspoint A
Input 1 to Crosspoint B
Negative Supply Voltage. Supply range is from -5.25V to 0.
Input 2 to Crosspoint A
Input 2 to Crosspoint B
Shunt Input to Crosspoint A. Use for shunt capacitor or AC ground connection to
improve off-isolation, or as an additional input to switch matrix A.
