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

to V

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

PRODUCT HIGHLIGHTS

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.

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.

Extended Signal Range. The enhanced LC

processing results in a high breakdown and an increased

analog signal range from V

Break-Before-Make Switching. Switches are guaranteed

break-before-make so that input signals are protected

against momentary shorting.

Low Leakage. Leakage currents in the range of 20 pA

make these multiplexers suitable for high precision circuits.
