SN74LV138ATDBR datasheet by Texas Instruments

SN74LV138ATDBR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74LV138ATDBR?
  The maximum operating frequency of the SN74LV138ATDBR is 100 MHz.
• Can I use the SN74LV138ATDBR in a 3.3V system?
  Yes, the SN74LV138ATDBR is compatible with 3.3V systems, but it can also operate at 1.65V to 5.5V supply voltage.
• How do I ensure that the SN74LV138ATDBR is properly powered down to minimize power consumption?
  To minimize power consumption, ensure that all inputs are at a valid logic level (either VCC or GND) and that the device is not in a floating state. Also, use the power-down feature by setting the enable inputs (E1, E2, and E3) to a logic low.
• What is the maximum current that the SN74LV138ATDBR can sink or source?
  The SN74LV138ATDBR can sink up to 24 mA and source up to -24 mA per output pin.
• Can I use the SN74LV138ATDBR in a high-temperature environment?
  The SN74LV138ATDBR is rated for operation from -40°C to 125°C, but it's recommended to derate the device for high-temperature operation to ensure reliable performance.
