3-to-8-line Decoder/Demultiplexer With Address Latch

The HD74HCT137 implements a three-to-eight line decoder with Latches on the three address inputs. When GL goes from low to high, the address present at the select inputs (A, B and C) is stored in the Latches As long as GL remains high no address changes will be recognized. Output enable controls, G1 and G2, control the state of the outputs independently of the select or latch-enable inputs. By Renesas Technology
