SN74LVC1G139DCTR Description

Short technical summary and product information.

The SN74LVC1G139DCTR from Texas Instruments is a single 2-line to 4-line decoder/demultiplexer. It is designed for high-performance memory-decoding or data-routing applications requiring short propagation delay times.

This device supports a wide operating voltage range from 1.65V to 5.5V, with inputs capable of accepting voltages up to 5.5V. It features a low quiescent current of 10µA maximum and an output drive of ±24mA at 3.3V. The maximum propagation delay is 4.9ns at 3.3V and 15pF.

Available in an 8-pin SM8 package, specifically 8-LSSOP and 8-MSOP, the SN74LVC1G139DCTR is suitable for surface mount applications. It is designed for high-speed memory systems where decoder delay is critical, ensuring negligible system delay.

The SN74LVC1G139DCTR also supports partial-power-down applications with Ioff circuitry, which prevents damaging current backflow when the device is powered down. It meets JESD 78 Class II latch-up performance and JESD22 ESD protection standards.
