SN74HC164DRG4 datasheet by Texas Instruments

SN74HC164DRG4 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the SN74HC164DRG4?
  The maximum clock frequency for the SN74HC164DRG4 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.
• Can I use the SN74HC164DRG4 with a 5V power supply?
  The SN74HC164DRG4 is designed to operate from 2V to 6V, but it's recommended to use a 3.3V or 5V power supply for optimal performance. However, it's essential to ensure that the input signals are within the recommended voltage range to avoid damage or incorrect operation.
• How do I handle the serial input data format for the SN74HC164DRG4?
  The SN74HC164DRG4 uses a serial input data format, where the data is shifted in through the SER (serial input) pin. The data should be clocked in on the rising edge of the clock signal, and the most significant bit (MSB) should be sent first.
• What is the propagation delay time for the SN74HC164DRG4?
  The propagation delay time for the SN74HC164DRG4 is typically around 10-15 ns, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing characteristics in the datasheet for specific propagation delay times.
• Can I use the SN74HC164DRG4 in a high-temperature environment?
  The SN74HC164DRG4 is rated for operation from -40°C to 125°C, but it's recommended to derate the device for high-temperature operation. It's essential to check the datasheet for specific temperature ratings and derating guidelines.
