STPIC6C595TTR datasheet by STMicroelectronics

STPIC6C595TTR Frequently Asked Questions (FAQs)

• What is the maximum frequency of the clock input?
  The maximum frequency of the clock input is 25 MHz, but it can be higher depending on the application and the quality of the clock signal.
• How do I ensure reliable data transfer over long cables?
  To ensure reliable data transfer over long cables, use twisted pair cables, keep the clock frequency as low as possible, and use a common ground between the transmitter and receiver.
• What is the maximum current that the output pins can sink/source?
  The maximum current that the output pins can sink/source is 25 mA per pin, but it's recommended to keep it below 10 mA to ensure reliable operation.
• Can I use the STPIC6C595TTR as a level shifter?
  Yes, the STPIC6C595TTR can be used as a level shifter, but it's not recommended as it's not designed for that purpose. Instead, use a dedicated level shifter IC for better performance and reliability.
• How do I handle errors and faults in the shift register?
  To handle errors and faults in the shift register, implement error detection and correction mechanisms, such as checksums or CRCs, and use the output enable pin to disable the outputs in case of an error.
