SN74ALS74AD datasheet by Texas Instruments

SN74ALS74AD Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74ALS74AD can handle?
  The maximum clock frequency of the SN74ALS74AD is typically 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74ALS74AD is properly reset during power-up?
  To ensure proper reset, connect the CLR (clear) input to a pull-up resistor and a capacitor to VCC. This will ensure that the flip-flop is reset during power-up.
• What is the recommended operating voltage range for the SN74ALS74AD?
  The recommended operating voltage range for the SN74ALS74AD is 4.5V to 5.5V, with a typical operating voltage of 5V.
• Can I use the SN74ALS74AD in a 3.3V system?
  While the SN74ALS74AD is typically used in 5V systems, it can be used in 3.3V systems with some limitations. However, the maximum clock frequency may be reduced, and the noise immunity may be affected.
• How do I interface the SN74ALS74AD with a microcontroller?
  To interface the SN74ALS74AD with a microcontroller, connect the clock input to a microcontroller output, and the data inputs to the microcontroller's data outputs. Ensure that the voltage levels and signal timing are compatible between the two devices.
