SN74HCS164BQAR Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the SN74HCS164BQAR is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing characteristics in the datasheet for specific frequency limits.
  • To ensure stable outputs during power-up, it's recommended to add a pull-up or pull-down resistor to the OE (output enable) pin to keep the outputs in a defined state until the device is fully powered up and configured.
  • Yes, the SN74HCS164BQAR can be used as a serial-to-parallel converter. The device can convert serial data from a single input pin to parallel data on the 8 output pins. However, it's essential to ensure that the clock signal is properly synchronized with the serial data input.
  • The maximum capacitive load that the SN74HCS164BQAR can drive is 100 pF. Exceeding this limit may affect the device's performance and reliability. It's recommended to check the capacitive load calculation in the datasheet to ensure that the device can drive the required load.
  • Yes, the SN74HCS164BQAR is compatible with both 3.3V and 5V logic levels. The device can operate with a supply voltage range of 2V to 6V, making it suitable for use in a variety of digital systems.
