Power Supply:
- Ensure the supply voltage (V_CC) is within the range of 2.0V to 6.0V.
- Connect the ground (GND) pin to a stable reference point.
Input Signals:
- Input signals should be within the valid logic levels:
  - Low (V_IL): -0.5V to 1.5V
  - High (V_IH): 3.5V to V_CC + 0.5V
Output Signals:
- Output signals will be:
  - Low (V_OL): -0.5V to 0.1V
  - High (V_OH): 2.7V to V_CC - 0.2V
Current Handling:
- The output can sink up to 8 mA and source up to 4 mA.
- Ensure that the load connected to the output does not exceed these limits.
Propagation Delay:
- The propagation delay time (t_pd) is typically 10 ns at 5V and 25掳C.
- Consider this delay when designing timing-sensitive circuits.
Temperature Range:
- The device operates reliably between -40掳C and 85掳C.
- Store the device between -65掳C and 150掳C.
Handling:
- Handle with care to avoid static damage.
- Follow proper soldering techniques to ensure reliable connections.
Testing:
- Before integrating into a larger system, test the device with known input signals to verify correct operation.
Decoupling Capacitors:
- Place decoupling capacitors (e.g., 0.1 渭F) close to the power pins to filter out noise and stabilize the power supply.
Layout:
- Ensure proper PCB layout to minimize signal interference and improve performance.
