GENERAL DESCRIPTION
The
and
are monolithic CMOS
devices containing four independently selectable switches. These
switches are designed on an advanced submicron process that
provides low power dissipation yet gives high switching speed, low
on resistance, low leakage currents, and high bandwidth.
They are designed to operate from a single 1.8 V to 5.5 V supply,
making them ideal for use in battery-powered instruments and
with the new generation of DACs and ADCs from Analog Devices,
Inc. Fast switching times and high bandwidth make the parts
suitable for switching USB 1.1 data signals and video signals.
The
and
contain four independent
single-pole/single-throw (SPST) switches. The
and
differ only in that the digital control logic is inverted. The
switches are turned on with a logic low on the appropriate
control input, while a logic high is required to turn on the switches
of the
The
contains two switches whose digital
control logic is similar to the
while the logic is inverted
on the other two switches.
Each switch conducts equally well in both directions when On. The
exhibits break-before-make switching action.

The
are available in 16-lead TSSOP
and 16-lead SOIC packages.
PRODUCT HIGHLIGHTS
1.
1.8 V to 5.5 V Single-Supply Operation.
The
and
offer high performance
and are fully specified and guaranteed with 3 V and 5 V
supply rails.
Very Low R
ON
(4.5 Ω maximum at 5 V, 8 Ω maximum at 3 V).
At supply voltage of 1.8 V, R
ON
is typically 35 Ω over the
temperature range.
Low On Resistance Flatness.
−3 dB Bandwidth >200 MHz.
Low Power Dissipation. CMOS construction ensures low
power dissipation.
Fast t

Break-Before-Make Switching.
This prevents channel shorting when the switches are
configured as a multiplexer (ADG713 only).
