GENERAL DESCRIPTION
The ADG741/ADG742 are monolithic CMOS SPST switches.
These switches are designed using an advanced submicron
process that provides low power dissipation, yet offers high
switching speed, low on resistance, and low leakage currents. In
addition, 3 dB bandwidths of greater than 200 MHz can be
achieved.
The ADG741/ADG742 can operate from a single 1.8 V to 5.5 V
supply, making them ideal for use in battery-powered instru-
ments and with Analog Devices’ new generation of DACs and
ADCs.
As shown in the Functional Block Diagrams, with a logic input
of 1 the switch of the ADG741 is closed, while that of the
ADG742 is open. Each switch conducts equally well in both
directions when on.
The ADG741/ADG742 are available in 6-lead and 5-lead SC70
packages.

PRODUCT HIGHLIGHTS
1.
1.8 V to 5.5 V Single-Supply Operation.
The ADG741/ADG742 offer high performance, including
low on resistance and fast switching times. They are fully
specified and guaranteed with 3 V and 5 V supply rails.
2.
Very Low RON (3 max at 5 V, 5 max at 3 V).
At 1.8 V operation, RON is typically 40 over the
temperature range.
3.
On Resistance Flatness RFLAT (ON) (1 max).
4.
3 dB Bandwidth >200 MHz.
5.
Low Power Dissipation.
CMOS construction ensures low power dissipation.
6.
Fast tON/tOFF.
7.
Tiny 6-Lead and 5-Lead SC70 Packages.
