74LVC138APW-Q100中文资料3-to-8 line decoder/demultiplexer; inverting数据手册Nexperia规格书

描述 Description

The 74LVC138A-Q100 is a 3-to-8 line decoder/demultiplexer. It accepts three binary weighted address inputs (A0, A1 and A2). When the inputs are enabled, it provides eight mutually exclusive outputs (Y0 to Y7) that are LOW when selected.
There are three enable inputs: two active LOW (E1 and E2) and one active HIGH (E3). Every output is 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 74LVC138A-Q100 devices and one inverter. The 74LVC138A-Q100 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
