The device converts the 2 digital bits into VPOS , VSS , or VNEG analog output voltages. An 8-bit input bus simultaneously inputs 4 groups of 2 bits each. The MXEI1480 consists of a selectable length Bidirectional Input Register, Transfer Latch, and 480 bit Level Shifter / Output Driver. Each OUT pin is switched to one of [VSS , VPOS , VNEG] according to the D0...D7 logic levels clocked into the MXEI1480, modified by the OE pin. The MXEI1480 is designed to operate over a temperature range of -40°C to +85°C, and is available as Gold Bumped Die in Waffle Pack, Gold Bumped Die in Wafer Form, and 70mm Wide Tape Carrier.
