74HCT137, 74HC237, High-Speed CMOS Logic 3 to 8-Line Decoder/Demultiplexer

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
