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.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
