4-channel multiplexer operation. See Truth Tables .
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 all switches open. See Truth Tables .
In parallel mode, this pin is the transparent Latch Enable. In the serial mode, this pin is the Chip-Select
Input. See Truth Tables.
Most Significant Address Bit in parallel mode with 4/8 low. If 4/8 pin is high, this pin is ignored. In the serial
mode, this is the Serial Shift Clock Input. Data is loaded on the rising edge of SCLK. See Truth Tables .
Address Input in the parallel mode. Serial Data Input in serial mode. In serial mode, data is loaded on
SCLK’s rising edge.
Least Significant Address Input in the parallel mode. In the serial mode this is an 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 .
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 LE signal is high.
Interface Select Input. Drive low for parallel data interface operation. Drive high for serial data interface
operation and to enable the DOUT driver.
Logic Supply Input. Powers the DOUT driver and other digital circuitry. V
output logic levels.
