Pin Information

General Description

The AS16M1 analog switch with serial digital interface

offers 16 individually controlled single-pole-change-

over (SPCO) switches. All switches conduct equally in

either direction and on-resistance (170

Ω) 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.
