SN74LS266D datasheet by Texas Instruments

SN74LS266D Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the SN74LS266D?
  The maximum frequency of operation for the SN74LS266D is typically around 30-40 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74LS266D is properly powered and decoupled?
  To ensure proper operation, the SN74LS266D should be powered from a stable 5V supply, and decoupling capacitors (e.g. 0.1uF) should be placed as close to the device as possible to filter out noise and reduce electromagnetic interference (EMI).
• What is the maximum current that the SN74LS266D can sink or source?
  The SN74LS266D can sink up to 16mA and source up to 2mA per output, but this can vary depending on the specific application and operating conditions.
• How do I handle the enable inputs (E1 and E2) to ensure proper operation?
  The enable inputs (E1 and E2) should be tied to a valid logic level (either VCC or GND) to ensure proper operation. Leaving these inputs floating can cause unpredictable behavior.
• What is the propagation delay time for the SN74LS266D?
  The propagation delay time for the SN74LS266D is typically around 10-15ns, but this can vary depending on the specific application and operating conditions.
