The ADG428 is a monolithic CMOS analog multiplexer comprising eight single channels. On-chip address and control latches facilitate microprocessor interfacing. The ADG428 switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1 and A2. An EN input on both devices is used to enable or disable the device. When disabled, all channels are switched OFF. All the control inputs, address and enable inputs are TTL compatible over the fully specified operating temperature range. This makes the part suitable for bus-controlled systems such as data acquisition systems, process controls, avionics and ATEs because the TTL compatible address latches simplify the digital interface design and reduce the board space required.Product HighlightsExtended Signal RangeThe ADG428/ADG429 are fabricated on an enhanced LC2MOS process, giving an increased signal range that extends to the supply rails.Low Power DissipationLow RONSingle/Dual Supply OperationSingle Supply OperationFor applications where the analog signal is unipolar, the ADG428/ADG429 can be operated from a single rail power supply. The parts are fully specified with a single +12 V power supply and will remain functional with single supplies as low as +5 V.ApplicationsAutomatic Test EquipmentData Acquisition SystemsCommunication SystemsAvionics and Military SystemsMicroprocessor Controlled Analog SystemsMedical Instrumentation
