SN54H103W datasheet by Texas Instruments

SN54H103W Frequently Asked Questions (FAQs)

• What is the recommended operating temperature range for the SN54H103W?
  The recommended operating temperature range for the SN54H103W is -55°C to 125°C.
• How do I handle the power-up and power-down sequences for the SN54H103W?
  It is recommended to power up the VCC pin first, followed by the input signals, and power down the input signals first, followed by the VCC pin to prevent latch-up and ensure proper operation.
• What is the maximum allowable voltage on the input pins of the SN54H103W?
  The maximum allowable voltage on the input pins of the SN54H103W is 5.5V, regardless of the VCC voltage.
• Can I use the SN54H103W in a 3.3V system?
  Yes, the SN54H103W can be used in a 3.3V system, but the input voltage thresholds and output voltage levels will be different from those in a 5V system. Refer to the datasheet for specific details.
• How do I ensure electromagnetic compatibility (EMC) with the SN54H103W?
  To ensure EMC, use proper PCB layout, decoupling, and shielding techniques, and follow the guidelines in the Texas Instruments application note 'EMC Guidelines for TI Logic Devices'.
