SN74LS194AD Frequently Asked Questions (FAQs)

  • The SN74LS194AD can operate at clock frequencies up to 25 MHz.
  • To ensure the shift register is properly cleared, apply a low pulse to the CLEAR input (CLR) before operating the device.
  • The maximum input voltage that can be applied to the SN74LS194AD is 5.5V.
  • Yes, the SN74LS194AD can be used in a 3.3V system, but the output voltage will be limited to 3.3V.
  • The SN74LS194AD can be interfaced with a microcontroller by connecting the clock input (CLK) to a microcontroller output, and the serial input (SER) to a microcontroller output. The microcontroller can then send data to the shift register by toggling the clock input.
