SN74LS682DW datasheet by Texas Instruments

SN74LS682DW Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74LS682DW?
  The maximum operating frequency of the SN74LS682DW is 30 MHz, but it can vary depending on the system design and capacitive loading.
• How do I ensure reliable operation of the SN74LS682DW in high-temperature environments?
  To ensure reliable operation in high-temperature environments, it is recommended to follow proper thermal management practices, such as providing adequate heat sinking and airflow, and ensuring that the device operates within its specified temperature range (-40°C to 85°C).
• Can I use the SN74LS682DW in a 3.3V system?
  The SN74LS682DW is a 5V device, but it can be used in a 3.3V system with some limitations. The device's input voltage threshold is typically around 2.5V, so it may not function correctly at 3.3V. However, Texas Instruments provides a 3.3V-compatible version of the device, the SN74LV682DW, which is recommended for 3.3V systems.
• How do I handle bus contention when using the SN74LS682DW?
  To handle bus contention when using the SN74LS682DW, it is recommended to use bus-hold circuits or resistors to prevent backdrive currents, and to ensure that the device is properly terminated to prevent reflections and oscillations.
• Is the SN74LS682DW compatible with TTL and CMOS logic levels?
  The SN74LS682DW is a TTL-compatible device, but it can also be used with CMOS logic levels. However, it is recommended to use a level translator or voltage regulator to ensure proper voltage levels and to prevent damage to the device.
