SN74ALS139DR Description

Short technical summary and product information.

The SN74ALS139DR from Texas Instruments is a dual 2-line to 4-line decoder/demultiplexer integrated circuit. It is designed for high-performance memory-decoding and data-routing applications requiring short propagation delay times. Each of the two decoders within the package features two enable inputs that simplify cascading and data reception.

 

The device operates with a single supply voltage ranging from 4.5V to 5.5V and has an operating temperature range of 0°C to 70°C. The SN74ALS139DR is available in a 16-SOIC package, suitable for surface mounting.

 

These decoders/demultiplexers are built using the ALS technology family. They feature fully buffered inputs, each presenting only one normalized load to the driving circuit. All inputs are clamped with Schottky diodes to suppress line ringing and simplify system design. The active-low enable input can also function as a data line in demultiplexing scenarios.
