The AS16M1 analog switch with serial digital interface offers 16 pairs
individually controlled single-pole-change-over (SPCO) switches. All
switches conduct equally in either direction and on-resistance (170
is constant over the analog signal range. These CMOS switches can
operate continuously with power supply +5V and switch input currents in
any combination to output node (summing) or ground them. Upon
power-up, all summing switches are off, grounding switches are on and
the internal serial and parallel shift registers are reset to zero.
The AS16M1 is controlled by a serial interface. The interface is
compatible with the SPI interface standard.
