SN54AHCT138 - 3-Line to 8-Line Decoders/Demultiplexers

General Description

The ’AHCT138 3-line to 8-line decoders/ demultiplexers are designed to be used in highperformance 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.

Key Features

  • Inputs are TTL-voltage compatible.
  • Designed specifically for high-speed memory decoders and data-transmission systems.
  • Incorporate three enable inputs to simplify cascading and/or data reception.
  • Latch-up performance exceeds 250mA per JESD 17.
  • ESD protection exceeds JESD 22.
  • ±2000V human-body model (A114-A).
  • ±1000V charged-device model (C101) 2.
