SN74LS174N datasheet by Texas Instruments

SN74LS174N Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LS174N can handle?
  The maximum clock frequency of the SN74LS174N is 25 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74LS174N is properly reset during power-up?
  To ensure proper reset, connect the CLR (clear) input to a pull-up resistor and a capacitor to ground. This will ensure that the device is properly reset during power-up.
• What is the recommended operating voltage range for the SN74LS174N?
  The recommended operating voltage range for the SN74LS174N is 4.75V to 5.25V, with a typical operating voltage of 5V.
• How do I handle the asynchronous clear input (CLR) during normal operation?
  During normal operation, the CLR input should be tied high to prevent accidental clearing of the registers. If a reset is required, the CLR input should be pulsed low for a minimum of 10 ns.
• What is the maximum capacitance that can be driven by the SN74LS174N outputs?
  The maximum capacitance that can be driven by the SN74LS174N outputs is 100 pF, but this can vary depending on the specific application and operating conditions.
