CMOS Latched 4-/8-Channel Analog Multiplexers ADG528A/ADG529A FEATURES 44 V Supply Maximum Rating VSS to VDD Analog Signal Range Single-/Dual-Supply Specifications Wide Supply Ranges (10.8 V to 16.5 V) Microprocessor Compatible (100 ns WR Pulse) Extended Plastic Temperature Range (–40°C to +85°C) Low Leakage (20 pA typ) Low Power Dissipation (28 mW max) Available in 18-Lead DIP/SOIC and 20-Lead PLCC Packages Superior Alternative to: DG528 DG529 FUNCTIONAL BLOCK DIAGRAMS GENERAL DESCRIPTION PRODUCT HIGHLIGHTS The ADG528A and ADG529A are CMOS monolithic analog multiplexers with eight channels and four dual channels, respectively. On-chip latches facilitate microprocessor interfacing. The ADG528A switches one of eight inputs to a common output, depending on the state of three binary addresses and an enable input. The ADG529A switches one of four differential inputs to a common differential output, depending on the state of two 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. The ADG528A and ADG529A 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 multiplexers also feature high switching and low RON. 2. Easily Interfaced The ADG528A and ADG529A 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 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. 5. Low Leakage Leakage currents in the range of 20 pA make these multiplexers suitable for high precision circuits. REV.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADG528A/ADG529A features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. REV. B –5– WARNING!
