XD74LS139 DIP16 / XL74LS139 SOP16 Schottky-clamped TTL MSI circuits

PublishTime：2021-05-19

These Schottky-clamped TTL MSI circuits 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 employed with high- speed memories utilizing a fast-enable circuit, the delay times of these decoders and the enable time of the memory are usually less than the typical access time of the memory. This means that the effective system delay introduced by the Schottky-clamped system decoder is negligible.
The circuit comprises two individual two-line to four-line decoders in a single package. The active-low enable input can be used as a data line in demultiplexing applications.
All of these decoders/demultiplexers feature fully buffered inputs, each of which represents only one normalized load to its driving circuit. All inputs are clamped with high-performance Schottky diodes to suppress line-ringing and to Simplify system design. The XD74LS139 and XL74LS139 are characterized for operation range of -55°C to 125°C. The XD74LS139 and XL74LS139 are characterized for operation from 0°C to 70 °C.
