SN54LS169BJ datasheet by Texas Instruments

SN54LS169BJ Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN54LS169BJ can operate at?
  The maximum clock frequency of the SN54LS169BJ is 25 MHz.
• How do I ensure that the SN54LS169BJ is properly powered?
  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.
• What is the maximum input voltage that the SN54LS169BJ can tolerate?
  The maximum input voltage that the SN54LS169BJ can tolerate is 5.5V, exceeding which may cause damage to the device.
• How do I handle the asynchronous reset input (CLR) of the SN54LS169BJ?
  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.
• Can I use the SN54LS169BJ in a 3.3V system?
  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.
