The IDT74FCT138D is a high-speed 1-of-8 decoder/demultiplexer fabricated with advanced CMOS technology by Integrated Device Technology (IDT). This device accepts three address inputs (A0-A2) and enables one of eight outputs based on the binary address applied to these inputs. The device features three enable inputs (E1, E2, and E3) to facilitate easy cascading for expansion to larger decoding networks. The low output impedance ensures excellent driving capability.
