SN74LS377N Frequently Asked Questions (FAQ)

  • The maximum clock frequency of the SN74LS377N is 10 MHz, but it can vary depending on the specific application and operating conditions.

  • To ensure proper power and decoupling, use a 5V power supply, add a 0.1uF ceramic capacitor between VCC and GND, and use a 10uF electrolytic capacitor between VCC and GND for bulk decoupling.

  • The SN74LS377N can sink up to 16mA and source up to 12mA per output, but it's recommended to limit the current to 8mA per output to ensure reliable operation.

  • The CLR input should be tied to VCC through a 1kΩ resistor and a 0.01uF capacitor to ensure proper reset operation. A low signal on CLR resets the counter.

  • No, the SN74LS377N is designed to operate at 5V and is not compatible with 3.3V systems. Using it in a 3.3V system may result in unreliable operation or damage to the device.
