SN74LS145NSR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS145NSR is 25 MHz.
  • The SN74LS145NSR requires a single 5V power supply, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper power supply decoupling.
  • The typical propagation delay of the SN74LS145NSR is 10ns, but it can vary depending on the operating conditions and load capacitance.
  • No, the SN74LS145NSR is designed to operate at 5V, and it's not recommended to use it in a 3.3V system. Using it at a lower voltage may affect its performance and reliability.
  • The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low. When OE is high, the outputs are in a high-impedance state.
