Design Tips and Best Practices

• When using near the lower supply limit (3 V), verify switching thresholds in your circuit to ensure reliable logic levels.
• Decouple the supply rails with a 0.1 μF ceramic capacitor close to the IC to reduce noise and improve stability.
• Keep input lines short and avoid floating inputs; tie unused inputs to Vcc or GND through appropriate resistors.
• For TTL interfacing, confirm input threshold compatibility, especially in mixed-voltage systems.
