M74HC4094TTR datasheet by STMicroelectronics

M74HC4094TTR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the M74HC4094TTR can handle?
  The M74HC4094TTR can handle clock frequencies up to 25 MHz.
• How do I ensure that the shift register is properly initialized?
  To ensure proper initialization, the shift register should be reset by applying a low pulse on the RST pin, and then the clock pin should be toggled 8 times to load the initial data.
• What is the maximum voltage that can be applied to the output pins?
  The maximum voltage that can be applied to the output pins is 5.5V, which is the maximum rating for the device.
• Can I use the M74HC4094TTR as a level shifter?
  Yes, the M74HC4094TTR 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 use as a shift register.
• How do I troubleshoot issues with the shift register not shifting correctly?
  To troubleshoot issues with the shift register not shifting correctly, check the clock signal, ensure that the RST pin is properly reset, and verify that the input data is correct. Also, check for any noise or glitches on the clock and data lines.
