Part Number : 74HCT138
Function :3-LINE TO 8-LINE DECODERS/DEMULTIPLEXERS
Manufacturer : Texas Instruments
Pinout : 
Description
The ’HCT138 devices are designed for high-performance memory-decoding 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 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.
