SN74LS465DW datasheet by Texas Instruments

SN74LS465DW Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LS465DW can handle?
  The maximum clock frequency of the SN74LS465DW is 20 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
• How do I ensure that the SN74LS465DW is properly powered and decoupled?
  To ensure proper power and decoupling, use a 5V power supply with a minimum of 10uF decoupling capacitor between VCC and GND, and place the capacitor as close to the device as possible.
• What is the maximum input voltage that the SN74LS465DW can tolerate?
  The maximum input voltage that the SN74LS465DW can tolerate is 5.5V, but it's recommended to keep the input voltage within the recommended operating range of 4.75V to 5.25V to ensure reliable operation.
• How do I handle the asynchronous reset input (R) of the SN74LS465DW?
  The asynchronous reset input (R) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure that the device is properly reset. A low-level input on R will reset the device.
• What is the propagation delay of the SN74LS465DW?
  The propagation delay of the SN74LS465DW is typically around 10ns to 15ns, but it can vary depending on the operating conditions and the load capacitance.
