SN74LVC138APWR Part Information

Details for SN74LVC138APWR by Texas Instruments

Semiconductors - ICs > Logic > Decoders / Encoders

Part Description

The SN74LVC138A devices are designed for highperformance memory-decoding or data-routing applications requiring very short propagation delay times. In high-performance memory systems, these decoders minimize the effects of system decoding. When employed with high-speed memories using a fast enable circuit, 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.
