SN74HC594DW datasheet by Texas Instruments

SN74HC594DW Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the SN74HC594DW?
  The maximum clock frequency for the SN74HC594DW is 25 MHz.
• Can I use the SN74HC594DW as a level shifter?
  Yes, the SN74HC594DW can be used as a level shifter, but it's not recommended as it's not designed for that purpose. It's primarily intended for serial-to-parallel data conversion.
• How do I ensure data integrity when using the SN74HC594DW?
  To ensure data integrity, use a clock frequency that is within the recommended range, ensure proper signal termination, and use a stable power supply. Additionally, consider using a CRC or checksum to detect data errors.
• Can I daisy-chain multiple SN74HC594DW devices?
  Yes, you can daisy-chain multiple SN74HC594DW devices to increase the number of output bits. Connect the QH' output of one device to the SER input of the next device.
• What is the maximum output current of the SN74HC594DW?
  The maximum output current of the SN74HC594DW is 25 mA per output pin.
