SN74HC74PWG4 datasheet by Texas Instruments

SN74HC74PWG4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74HC74PWG4?
  The recommended operating voltage range for the SN74HC74PWG4 is 2V to 6V, with a typical voltage of 5V.
• How do I handle the power-up and power-down sequences for the SN74HC74PWG4?
  It is recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This ensures that the device is properly initialized and avoids any potential latch-up conditions.
• What is the maximum clock frequency that the SN74HC74PWG4 can handle?
  The maximum clock frequency that the SN74HC74PWG4 can handle is 25 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74HC74PWG4 is properly decoupled from the power supply?
  It is recommended to use a 0.1uF ceramic capacitor between the VCC pin and the GND pin to decouple the device from the power supply. This helps to reduce noise and ensure stable operation.
• What is the maximum current that the SN74HC74PWG4 can sink or source?
  The maximum current that the SN74HC74PWG4 can sink or source is 25mA per output pin, but this can vary depending on the specific application and operating conditions.
