ANALOG DEVICES CMOS Latched 8/16 Channel Analog Multiplexers ADG526A/ADG527A FEATURES 44V Supply Maximum Rating Vss to Vpp Analog Signal Range Single/Dual Supply Specifications Wide Supply Ranges (10.8V to 16.5V) Microprocessor Compatible (100ns WR Pulse) Extended Plastic Temperature Range (-40C to + 85C) Low Leakage (20pA typ) Low Power Dissipation (28mW max) Available in DIP, SOIC, PLCC and LCCC Packages Superior Alternative to: DG526 DG527 GENERAL DESCRIPTION The ADGS26A 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 de- pending on the state of four binary addresses and an enable input. The ADG527A switches one of 8 differential inputs to a common differential output depending on the state of three binary addresses and an enable input. Both devices have TTL and 5V CMOS logic compatible digital inputs. The ADG526A and ADGS527A are designed on an enhanced LC?MOS process which gives an increased signal capability of Vsg to Vpp and enables operation over a wide range of supply voltages. The devices can comfortably operate anywhere in the 10.8V to 16.5V single or dual supply range. These multiplexers also feature high switching speeds and low Ron. REV.

FUNCTIONAL BLOCK DIAGRAMS ADG526A ADG527A DECODER/ LATCHES OO-O-O-0-O AO A1 A2 A3 ENRS AO Al A2 EN RS PRODUCT HIGHLIGHTS 1. Single/Dual Supply Specifications with a Wide Tolerance: The devices are specified in the 10.8V to 16.5V range for both single and dual supplies. 2. Easily Interfaced: The ADGS26A 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 micro- processor reset pin. 3. Extended Signal Range: The enhanced LC2MOS processing results in a high breakdown and an increased analog signal range of Vss to Vpp. 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 20pA make these multiplexers suitable for high precision circuits. One Technology Way, P.O. Box 9106, Norwood, MA 02062-9106, U.S.A.
