HD74LV139A中文资料瑞萨数据手册PDF规格书

描述 Description

The HD74LV139A has two independent two-to-four-line decoders each with a single active low enable input in a 16 pin package. Data on the select inputs cause one of the four normally high outputs to go low. Low voltage and highspeed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.
