| Overview | The 74HC137 decodes three binary weighted address inputs (A0, A1 and A2) to eight mutually exclusive outputs (Y0 to Y7). The device features a latch enable (LE) and two output enable (E1, E2) inputs. . a latch enable (LE) and two output enable (E1, E2) inputs. A LOW on LE causes the device to act as an active LOW decoder. A LOW-to HIGH transition on LE stores the data that was present before the transition in the latches. Further address changes are ignored as long as LE remains HIGH. The output e. |

| Overview |
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 out.
