The SN74HC139 is a device designed for high-performance memory decoding or data routing applications that require very short propagation delay times. It is suitable for high-performance memory systems and can minimize the effects of system decoding. When used with high-speed memories utilizing a fast enable circuit, the delay time of this decoder 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 decoder is negligible.
