General Description

/ordering information The ’AC139 devices are dual 2-line to 4-line decoders/demultiplexers designed for 1.5-V to 5.5-V VCC operation.

These devices are designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times.

In high-performance memory systems, these decoders can be used to minimize the effects of system decoding.
