Texas Instruments
74HC137
Part Number 74HC137
Manufacturer Texas Instruments
Title High-Speed CMOS Logic 3 to 8-Line Decoder/Demultiplexer
Description Both circuits have three binary select inputs (A0, A1 and A2) that can be latched by an active High Latch Enable (LE) signal to isolate the outputs from select-input changes. A “Low” LE makes the output transparent to the input and the circuit functions as a one-of-eight decoder. Two Output Enable .
Features
