DUAL 2-LINE TO 4-LINE DECODERS/DEMULTIPLEXERS

The HC139 are designed for high-performance memory-decoding SN54HC139 SN74HC139 or data-routing applications requiring very short propagation delay times. In high-performance memory systems, these decoders CAN minimize the effects of system decoding. When employed with high-speed Memories utilizing a fast enable circuit, the delay time of these decoders and the enable time of the memory are usually less than the typical access time of the memory. This means that the effective system delay introduced by the decoders is negligible. The HC139 comprise two individual 2-line to 4-line decoders in a single package. 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. The SN54HC139 is characterized for operation over the full military temperature range of 55C to 125C. The SN74HC139 is characterized for operation from 40C to 85C. By Texas Instruments
