description/ordering information

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. When used with high-speed memories

utilizing a fast enable circuit, the delay times of these decoders and the enable time of the memory usually are

less than the typical access time of the memory. This means that the effective system delay introduced by the

decoders is negligible.

The active-low enable (G) input can be used as a data line in demultiplexing applications. These

decoders/demultiplexers feature fully buffered inputs, each of which represents only one normalized load to its

driving circuit.
