SN74HC594D datasheet by Texas Instruments

SN74HC594D Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the SN74HC594D?
  The maximum clock frequency for the SN74HC594D is 25 MHz.
• Can I use the SN74HC594D as a latch?
  Yes, the SN74HC594D can be used as a latch by tying the clock input (CLK) high and using the serial input (SER) to load data into the shift register.
• How do I reset the SN74HC594D?
  The SN74HC594D has an asynchronous reset input (RCLR) that can be used to reset the shift register. When RCLR is low, the shift register is reset and all outputs are set low.
• What is the propagation delay time for the SN74HC594D?
  The propagation delay time for the SN74HC594D is typically around 10-15 ns, but this can vary depending on the operating conditions and load capacitance.
• Can I use the SN74HC594D with a 5V power supply?
  Yes, the SN74HC594D is compatible with 5V power supplies, but it can also operate with power supplies as low as 2V. However, the maximum clock frequency may be reduced at lower power supply voltages.
