描述 Description

The AiP74LVC138 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 outputs (Y(—)0 to Y(—)7) that are LOW when selected.There are three enable inputs: two active LOW (E(—)1 and E(—)2) and one active HIGH (E3). Every output will be HIGH unless E(—)1 and E(—)2 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 AiP74LVC138 devices and one inverter. The AiP74LVC138 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.
