Power Supply Connection:
- Connect the supply voltage (V_CC) to pin 14 and ground (GND) to pin 7. Ensure that the supply voltage is within the operating range of 2.0V to 6.0V.
Input Signals:
- Apply input signals to pins as specified by the logic function of the device. The input voltages should be within the valid input voltage levels defined in the table above.
Output Connections:
- Outputs can drive TTL, CMOS, or similar logic families. Ensure load currents do not exceed the output current ratings.
Propagation Delay:
- Consider the propagation delay when designing timing-sensitive circuits. The typical propagation delay is 12ns under standard conditions.
Handling Precautions:
- This device is sensitive to electrostatic discharge (ESD). Handle with care and use appropriate ESD protection measures.
Operating Temperature:
- The device operates reliably over a temperature range from -40°C to +85°C. Ensure that the ambient temperature does not exceed these limits.
Mounting Orientation:
- Mount the device according to the manufacturer’s guidelines to ensure proper heat dissipation and mechanical stability.
Storage and Handling:
- Store in a dry environment and handle carefully to avoid damage to the leads or the body of the component.
