GENERAL DESCRIPTION
The ADG526A and ADG527A are CMOS monolithic analog
multiplexers with 16 single channels and dual 8 channels,
respectively. On-chip latches facilitate microprocessor interfacing.
The ADG526A switches one of 16 inputs to a common output,
depending on the state of four binary addresses and an enable
input. The ADG527A switches one of eight differential inputs to
a common differential output, depending on the state of three
binary addresses and an enable input. Both devices have TTL
and 5 V CMOS logic-compatible digital inputs.
The ADG526A and ADG527A are designed on an enhanced
LC
2
MOS process that gives an increased signal capability of V
SS
to V
DD
and enables operation over a wide range of supply
voltages. The devices can comfortably operate anywhere in the
10.8 V to 16.5 V single- or dual-supply range. These multiplexers
also feature high switching speeds and low R
ON
.

PRODUCT HIGHLIGHTS
1. Single- or Dual-Supply Specifications with a Wide
Tolerance. The devices are specified in the 10.8 V to
16.5 V range for both single and dual supplies.
2. Easily Interfaced. The ADG526A and ADG527A can be
easily interfaced with microprocessors. The
WR
signal
latches the state of the address control lines and the enable
line. The
RS
signal clears both the address and enable data
in the latches, resulting in no output (all switches off).
RS
can be tied to the microprocessor reset pin.
3. Extended Signal Range. The enhanced LC
2
MOS
processing results in a high breakdown and an increased
analog signal range from V
SS
to V
DD
.
4. Break-Before-Make Switching. Switches are guaranteed
break-before-make so that input signals are protected
against momentary shorting.
5. Low Leakage. Leakage currents in the range of 20 pA
make these multiplexers suitable for high precision circuits.
