SN74LS196D datasheet by Texas Instruments

SN74LS196D Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74LS196D can handle?
  The maximum clock frequency of the SN74LS196D is 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the timing diagrams and specifications in the datasheet for more information.
• How do I ensure that the SN74LS196D is properly powered and decoupled?
  To ensure proper power and decoupling, connect the VCC pin to a stable 5V power supply, and decouple the power pins with 0.1uF ceramic capacitors. Additionally, use a 10uF electrolytic capacitor to filter out any noise on the power line.
• What is the maximum current that the SN74LS196D can sink or source?
  The SN74LS196D can sink up to 16mA and source up to 2mA per output pin. However, it's recommended to check the absolute maximum ratings in the datasheet to ensure that the device is not damaged.
• How do I handle the asynchronous reset input (R) on the SN74LS196D?
  The asynchronous reset input (R) should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure that the device is properly reset. When the reset input is low, the device is reset, and all outputs are set to a logic low state.
• What is the propagation delay of the SN74LS196D?
  The propagation delay of the SN74LS196D varies depending on the operating voltage and temperature. Typically, the propagation delay is around 10-20ns, but it's recommended to check the timing diagrams and specifications in the datasheet for more information.
