CD74HC164M96 datasheet by Texas Instruments

CD74HC164M96 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the CD74HC164M96?
  The maximum clock frequency for the CD74HC164M96 is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing diagrams in the datasheet for specific frequency limits.
• How do I ensure that the shift register is properly reset after power-on?
  To ensure proper reset, connect the MR (Master Reset) pin to a logic high level during power-on, and then release it after the power supply has stabilized. This ensures that the shift register is reset to a known state.
• What is the maximum capacitance that can be driven by the CD74HC164M96 outputs?
  The CD74HC164M96 can drive up to 50 pF of capacitance on each output pin. Exceeding this limit may cause signal degradation or oscillations.
• Can I use the CD74HC164M96 as a serial-to-parallel converter?
  Yes, the CD74HC164M96 can be used as a serial-to-parallel converter. Simply clock in the serial data, and then latch the data using the parallel output enable (OE) pin.
• How do I minimize power consumption when using the CD74HC164M96?
  To minimize power consumption, use a low-frequency clock, reduce the operating voltage, and minimize the number of output transitions. You can also use the power-down mode (PD) pin to reduce power consumption when the device is not in use.
