GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
The ADG526A and ADG527A are CMOS monolithic analog  
multiplexers with 16 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.  
1. Single/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.  
The ADG526A and ADG527A are designed on an enhanced  
LC2MOS process which gives an increased signal capability of  
VSS to VDD 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 multiplex-  
3. Extended Signal Range: The enhanced LC2MOS processing  
results in a high breakdown and an increased analog signal  
range of VSS to VDD  
.
4. Break-Before-Make Switching: Switches are guaranteed  
break-before-make so that input signals are protected against  
momentary shorting.  
ers also feature high switching speeds and low RON  
.
5. Low Leakage: Leakage currents in the range of 20 pA make  
these multiplexers suitable for high precision circuits.
