SN54S20J datasheet by Texas Instruments

SN54S20J Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the SN54S20J?
  The SN54S20J can operate from -55°C to 125°C, but the recommended operating temperature range is 0°C to 70°C for optimal performance.
• How do I handle the input voltage range for the SN54S20J?
  The recommended input voltage range for the SN54S20J is 4.5V to 5.5V. Operating outside this range may affect the device's performance and reliability.
• What is the maximum clock frequency supported by the SN54S20J?
  The SN54S20J can support clock frequencies up to 100 MHz, but the recommended frequency range is 1 MHz to 50 MHz for optimal performance.
• How do I ensure proper power sequencing for the SN54S20J?
  To ensure proper power sequencing, apply power to the VCC pin before applying any input signals, and ensure that the power supply is stable before enabling the clock signal.
• What is the recommended termination scheme for the SN54S20J?
  The recommended termination scheme for the SN54S20J is to use a 50-ohm termination resistor in series with the output pin, and a 50-ohm pull-up resistor to VCC for each output pin.
