SN74LS169BN datasheet by Texas Instruments

SN74LS169BN Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LS169BN can handle?
  The maximum clock frequency of the SN74LS169BN is 2 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74LS169BN is properly powered and decoupled?
  To ensure proper power and decoupling, use a 5V power supply, decouple the power pins with 0.1uF and 10uF capacitors, and use a 10kΩ pull-up resistor on the clock input.
• What is the maximum current that the SN74LS169BN can sink or source?
  The SN74LS169BN can sink up to 16mA and source up to 2mA per output pin.
• How do I reset the SN74LS169BN counter?
  The SN74LS169BN has an asynchronous reset input (RST) that can be used to reset the counter to zero. Apply a low signal to the RST pin to reset the counter.
• Can I use the SN74LS169BN as a programmable divider?
  Yes, the SN74LS169BN can be used as a programmable divider by using the preset enable (PE) input to load a preset value into the counter.
