HD74LV139A Datasheet | Hitachi Semiconductor

Description The HD74LV139A is designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times. The active-low enable input can be used as a data line in demultiplexing applications. This decoder/demultiplexer features fully buffered inputs, each of which represents only one normalized load to its driving circuit. Low-voltage and high-speed operation is suitable for the battery-powered products (e.g., notebook puters), and the low-power consumption extends the battery life.
