SN74HCT74DRG4 datasheet by Texas Instruments

SN74HCT74DRG4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HCT74DRG4?
  The maximum operating frequency of the SN74HCT74DRG4 is typically around 30 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the power-up and power-down sequencing of the SN74HCT74DRG4?
  It is recommended to power up the VCC pin before applying any input signals, and to power down the VCC pin after removing all input signals. This helps to prevent unwanted latch-up or damage to the device.
• What is the recommended operating voltage range for the SN74HCT74DRG4?
  The recommended operating voltage range for the SN74HCT74DRG4 is 4.5V to 5.5V, with a typical operating voltage of 5V.
• How do I ensure that the SN74HCT74DRG4 is properly decoupled from the power supply?
  It is recommended to use a 0.1uF ceramic capacitor between the VCC pin and GND pin, and to place it as close to the device as possible. This helps to decouple the device from the power supply and reduce noise.
• What is the maximum current that the SN74HCT74DRG4 can sink or source?
  The maximum current that the SN74HCT74DRG4 can sink or source is typically around 20mA per output pin, but it can vary depending on the specific application and operating conditions.
