SN74AHCT138D 3-Line to 8-Line Decoders/Demultiplexers

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. PART NUMBER SNx4AHCT138 Device Information PACKAGE (1) PAC.

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
