SN54LS169BJ Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN54LS169BJ is 25 MHz.
  • The SN54LS169BJ 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 operation.
  • The maximum input voltage that the SN54LS169BJ can tolerate is 5.5V, exceeding which may cause damage to the device.
  • The CLR input should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure proper reset operation. A low-going pulse on CLR will reset the counter.
  • No, the SN54LS169BJ is a 5V device and is not compatible with 3.3V systems. Using it in a 3.3V system may cause malfunction or damage to the device.
