Instructions for Use

1. Power Supply Connection:

   • Connect the positive supply voltage (VDD) to pin 14.
   • Connect the ground (GND) to pin 7.

2. Input Connections:

   • Ensure input signals are within the specified VIH and VIL ranges to avoid undefined behavior.
   • Use pull-up or pull-down resistors if necessary to maintain stable logic levels when inputs are not driven.

3. Output Connections:

   • Outputs can drive up to 10 standard CMOS loads directly.
   • For driving TTL loads, use a suitable buffer or level translator.

4. Handling Precautions:

   • The device is sensitive to electrostatic discharge (ESD); handle with care.
   • Avoid exceeding the maximum ratings listed in the parameter table.

5. Layout Considerations:

   • Keep power and ground paths short and direct to minimize noise.
   • Use bypass capacitors (typically 0.1 μF) close to the power pins for stability.

6. Temperature Management:

   • Ensure adequate ventilation or cooling if operating near the upper temperature limit.
   • Monitor ambient temperature to prevent overheating.

7. Storage and Handling:

   • Store in a dry environment within the specified storage temperature range.
   • Follow anti-static precautions during handling and installation.
