Pin Description
Interface Select Input. Drive low for parallel data interface operation. Drive high for serial data interface
operation and to enable the DOUT driver.
SER/PAR
20
Analog Switch Common Terminal. See
Truth Tables.
COM2
19
Analog Negative Supply Voltage Input. Connect to GND for single-supply operation.
V-
18
Normally Open Analog Input Terminal. See
Truth Tables.
NO3
17
Normally Open Analog Input Terminal. See
Truth Tables.
NO4
15
Logic Supply Input. Powers the DOUT driver and other digital circuitry. VL sets both the input threshold
levels and the output logic levels.
VL
14
In parallel mode this pin is the transparent Latch Enable. In the serial mode, this pin is the Chip-Select input.
See
Truth Tables.
LE/CS
9
In parallel mode, A1/SCLK is the most significant address bit. If 2/4 is high, A1/SCLK is ignored. In the serial
mode, A1/SCLK is the serial shift clock input. Data is loaded on the rising edge of SCLK. See
Truth Tables.
A1/SCLK
10
In parallel mode, this pin is the least significant address bit. In serial mode, DOUT is the output from the
internal 4-bit shift register. DOUT is intended for daisy-chain cascading. DOUT is not three-stated by CS.
See
Serial Operation.
A0/DOUT
11
Switch Enable. Drive EN low to force all channels off. Drive high to allow normal multiplexer operation.
Operates asynchronously in serial mode. In parallel mode, EN is latched when the LE signal is high.
EN
12
Serial Data Input. In serial mode, data is loaded on the rising edge of SCLK. Connect to VL or GND in
parallel mode.
DIN
13
Normally Open Analog Input Terminal. See
Truth Tables.
NO2
6
Multiplexer Configuration Control. Connect to VL to select dual 2-channel mode. Connect to GND for single
4-channel multiplexer operation. See
Truth Tables.
2/4
7
Active-Low Reset Input. In serial mode, drive RS low to force the latches and shift registers to the power-on
reset state and force all switches open. In parallel mode, drive RS low to force the latches to the power-on
reset state and force switches open. See
Truth Tables.
RS
8
Normally Open Analog Input Terminal. See
Truth Tables.
NO1
4
Analog Positive Supply Voltage Input
V+
