74LCX74BQX Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the 74LCX74BQX is 1.65V to 3.6V, with a typical voltage of 3.3V.
  • 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 or damage.
  • The maximum frequency of operation for the 74LCX74BQX is 100 MHz, but this can vary depending on the specific application and operating conditions.
  • The 74LCX74BQX requires proper termination to prevent signal reflections and ensure reliable operation. This can be achieved by using a termination resistor (e.g. 22 ohms) at the output of the device, and/or using a transmission line with a characteristic impedance of 50 ohms.
  • The maximum output current that the 74LCX74BQX can sink or source is 24 mA, but this can vary depending on the specific application and operating conditions.
