| MC74LCX139 Dual Low-Voltage CMOS 2-to-4 Decoder/Demultiplexer With 5V-Tolerant Inputs The MC74LCX139 is a high performance, 2-to-4 decoder/ demultiplexer operating from a 2.3 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows MC74LCX139 inputs to be safely driven from 5 V devices. The MC74LCX139 is suitable for memory address decoding and other TTL level bus oriented applications. The MC74LCX139 high-speed 2-to-4 decoder/demultiplexer accepts two binary weighted inputs (A0, A1) and, when enabled, provides four mutually exclusive active-LOW outputs. The LCX139 features an active low Enable input. All outputs will be HIGH unless En is LOW. The LCX139 can be used as an 8-output demultiplexer by using one of the active-LOW Enable inputs as the data input and the other Enable input as a strobe. The Enable inputs which are not used must be permanently tied to ground. Current drive capability is 24 mA at the outputs.
