GENERAL DESCRIPTION
with a serially-controlled 3-wire interface. The ADG738 is an
8-channel matrix switch, while the ADG739 is a dual 4-channel
matrix switch. On resistance is closely matched between switches
and very flat over the full signal range.

that is compatible with SPI, QSPI, MICROWIRE, and some
DSP interface standards. The output of the input shift register,
DOUT, enables a number of these parts to be daisy-chained.
On power-up, the internal input shift register contains all zeros
and all switches are in the off state.
Each switch conducts equally well in both directions when on,
making these parts suitable for both multiplexing and demulti-
plexing applications. As each switch is turned on or off by a
separate bit, these parts can also be configured as a type of
switch array, where any, all, or none of the eight switches may
be closed at any time. The input signal range extends to the
supply rails.
All channels exhibit break-before-make switching action,
preventing momentary shorting when switching channels.
