SN74ABT126N datasheet by Texas Instruments

SN74ABT126N Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ABT126N?
  The maximum operating frequency of the SN74ABT126N 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 SN74ABT126N?
  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 SN74ABT126N?
  The recommended termination scheme for the SN74ABT126N is to use a series resistor (Rs) and a parallel capacitor (Cp) at the output of each buffer. The values of Rs and Cp depend on the specific application and operating frequency.
• How do I ensure signal integrity when using the SN74ABT126N in a high-speed application?
  To ensure signal integrity, it is recommended to use controlled impedance PCB traces, minimize trace lengths, and use signal termination. Additionally, consider using a signal integrity analysis tool to simulate and optimize the signal transmission.
• What is the maximum input voltage that the SN74ABT126N can tolerate?
  The maximum input voltage that the SN74ABT126N can tolerate is 5.5V, which is the absolute maximum rating. However, it is recommended to keep the input voltage within the recommended operating range of 3.5V to 5V to ensure reliable operation.
