SN74LV245ADGVR datasheet by Texas Instruments

SN74LV245ADGVR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74LV245ADGVR?
  The maximum operating frequency of the SN74LV245ADGVR is 100 MHz, but it can vary depending on the system design and capacitive loading.
• How do I ensure signal integrity when using the SN74LV245ADGVR?
  To ensure signal integrity, use proper PCB design techniques, such as using short signal traces, minimizing impedance mismatch, and adding termination resistors if necessary. Also, follow the recommended operating conditions and power supply decoupling guidelines.
• Can I use the SN74LV245ADGVR in a 3.3V system?
  Yes, the SN74LV245ADGVR is compatible with 3.3V systems. It has a wide operating voltage range of 2.0V to 5.5V, making it suitable for use in 3.3V systems.
• How do I handle the direction control pin (DIR) in my design?
  The direction control pin (DIR) determines the direction of data flow. Connect it to VCC or GND to set the direction of data flow. If DIR is connected to VCC, data flows from A to B, and if DIR is connected to GND, data flows from B to A.
• What is the maximum current that the SN74LV245ADGVR can sink or source?
  The SN74LV245ADGVR can sink or source up to 24 mA of current per output pin, but it's recommended to limit the current to 12 mA per pin to ensure reliable operation.
