MC74LCX139 - Dual Low Voltage CMOS 2-to-4 Decoder/Demultiplexer

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. Features.
  • Designed for 2.3 to 3.6 V VCC Operation.
  • 5 V Tolerant Inputs.
  • Interface Capability With 5 V TTL Logic.

MC74LCX139 Dual Low-Voltage CMOS 2-to-4 Decoder/Demultiplexer With 5 V−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.
