SN74LS145D Frequently Asked Questions (FAQs)

  • The SN74LS145D can handle clock frequencies up to 30 MHz.
  • The SN74LS145D 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 reduce noise and ensure stable operation.
  • The propagation delay of the SN74LS145D is typically around 10-15 ns, but this can vary depending on the specific application and operating conditions.
  • No, the SN74LS145D is designed to operate at 5V, and using it in a 3.3V system may not provide reliable operation and may even damage the device.
  • The output enable (OE) pin is active-low, meaning that the outputs are enabled when OE is low (connected to GND) and disabled when OE is high (connected to VCC).
