Логическая ИС SN74AHC139D

Декодер / демультиплексор , семейство HC, 8 выходов, 8мА, 2В - 5.5В, SOIC-16

The SN74AHC139D is a 2-to-4 dual Decoder/Demultiplexer for 2 to 5.5V VCC operation. It is 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 usually are less than the typical access time of the memory. This means that the effective system delay introduced by the decoders is negligible.

• Designed specifically for high-speed memory decoders and data-transmission systems
• Incorporate two enable inputs to simplify cascading and/or data reception
• Latch-up performance exceeds 250mA per JESD 17
• Green product and no Sb/Br
