    description/ordering information
    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.
