ADG529A

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 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. 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. PRODUCT HIGHLIGHTS 1.
