74LV138: 3-to-8 line decoder/demultplexer; inverting (Based on PIP 74LV138)
The 74LV138 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC138 and 74HCT138.
The 74LV138 is a 3-to-8 line decoder/demultiplexer. It accepts three binary weighted address
inputs (A0, A1 and A2) and, when enabled, provides eight mutually exclusive active LOW
outputs (Y0 to Y7).
There are three enable inputs: two active LOW (E1 and E2) and one active HIGH (E3). Every output will be HIGH unless E1 and E2 are LOW and E3 is HIGH.
This multiple enable function allows easy parallel expansion of the device to a 1-of-32 (5 lines to 32 lines) decoder with just four 74LV138 devices and one inverter. The 74LV138 can be used as an eight output demultiplexer by using one of the active LOW enable inputs as the data input and the remaining enable inputs as strobes. Unused enable inputs must be permanently tied to their appropriate active HIGH or LOW state.
