SN74LS596N datasheet by Texas Instruments

SN74LS596N Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LS596N can handle?
  The maximum clock frequency of the SN74LS596N is 25 MHz, but it can vary depending on the operating conditions and the quality of the clock signal.
• How do I ensure that the SN74LS596N is properly powered and decoupled?
  To ensure proper power and decoupling, use a 5V power supply with a minimum of 10uF decoupling capacitor between VCC and GND, and place the capacitor as close to the device as possible.
• What is the maximum current that the SN74LS596N can sink or source?
  The SN74LS596N can sink up to 24mA and source up to 15mA per output, but it's recommended to limit the current to 10mA per output to ensure reliable operation.
• How do I handle the asynchronous reset input (RST) of the SN74LS596N?
  The RST input should be asserted low for at least 10ns to ensure a proper reset. It's recommended to use a pull-up resistor to VCC to prevent floating inputs.
• Can I use the SN74LS596N in a 3.3V system?
  No, the SN74LS596N is a 5V device 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.
