description/ordering informationThe ’AHCT138 3-line to 8-line decoders/demultiplexers are designed to be used in high-performance
memory-decoding and data-routing applications that require very short propagation-delay times. In
high-performance memory systems, this decoder can be used to minimize the effects of system decoding.
When employed with high-speed memories utilizing a fast enable circuit, the delay times of this decoder 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 decoder is negligible.
ORDERING INFORMATION Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines
are available at www.ti.com/sc/package.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
