ADG527A

CMOS Latched 8-/16-Channel Analog Multiplexers ADG526A/ADG527A FEATURES 44 V supply maximum rating VSS to VDD analog signal range Single- or 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 typical) Low power dissipation (28 mW maximum) Available in PDIP, CERDIP, SOIC, and PLCC packages Superior alternative to DG526 and DG527 APPLICATIONS Data acquisition systems Communication systems Automatic test equipment Microprocessor controlled systems 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 LC2MOS process that 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 speeds and low RON. FUNCTIONAL BLOCK DIAG...
