SN74ALS139NSR Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the SN74ALS139NSR is 4.5V to 5.5V, with a typical voltage of 5V.

  • When the input pins are not in use, they should be tied to a valid logic level (either VCC or GND) to prevent them from floating and causing unwanted behavior.

  • The maximum frequency of operation for the SN74ALS139NSR is typically around 100 MHz, but this can vary depending on the specific application and operating conditions.

  • To ensure reliable operation over the full temperature range (-40°C to 85°C), it is recommended to follow proper PCB design and layout guidelines, use a stable power supply, and ensure that the device is operated within its recommended operating conditions.

  • The typical propagation delay for the SN74ALS139NSR is around 10-15 ns, but this can vary depending on the specific application and operating conditions.
