Overview
SN54AHCT139, SN74AHCT139 DUAL 2-LINE TO 4-LINE DECODERS/DEMULTIPLEXERS D Inputs Are TTL-Voltage Compatible D Designed Specifically for High-Speed Memory Decoders and Data-Transmission Systems D Incorporate Two Enable Inputs to Simplify Cascading and/or Data Reception D Latch-Up Performance Exceeds 250 mA Per JESD 17 D ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) – 1000-V Charged-Device Model (C101) description/ordering information The ’AHCT139 devices are dual 2-line to 4-line decoders/demultiplexers designed for 4.
5-V to 5.
5-V VCC operation.
These devices are designed to be used in high-performance memory-decoding or data-routing applications requiring very short propagation delay times.
In high-performance memory systems, these decoders can be used to minimize the effects of system decoding.
When used with high-speed memories utilizing a fast enable circuit, the delay times of these decoders and the enable time of the memory usuall...
