SN74F260DR datasheet by Texas Instruments

SN74F260DR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74F260DR?
  The maximum operating frequency of the SN74F260DR is 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the power-up and power-down sequencing of the SN74F260DR?
  It is recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This ensures that the device is properly initialized and avoids any potential latch-up or damage.
• What is the recommended termination scheme for the SN74F260DR?
  The recommended termination scheme for the SN74F260DR is to use a 50-ohm termination resistor at the output of each driver, and a 1-kohm pull-up resistor at the input of each receiver. This ensures proper signal integrity and minimizes reflections.
• Can I use the SN74F260DR in a 3.3V system?
  Yes, the SN74F260DR can be used in a 3.3V system, but it is recommended to use a voltage regulator or level translator to ensure that the input signals are within the recommended operating range of 4.5V to 5.5V.
• How do I handle the thermal management of the SN74F260DR?
  The SN74F260DR has a maximum junction temperature of 150°C. To ensure proper thermal management, it is recommended to use a heat sink or thermal pad, and to keep the device away from other heat sources.
