Instructions for Use:

1. Supply Voltage: The SN75451BP operates within a supply voltage range of 4.5V to 5.5V. Ensure the power supply is stable and within this range to avoid damage or erratic behavior.
2. Output Current: Each output pin can source or sink up to 20mA continuously. For peak currents up to 100mA, ensure these are non-repetitive to prevent overheating.
3. Input Voltage: Input signals should be within the range of 0V to 5.5V. Exceeding these limits can cause damage to the device.
4. Input Current: Each input pin draws a typical current of 1mA. Design your circuit to account for this current draw.
5. Propagation Delay: The propagation delay time is typically 35ns. This is important for timing considerations in high-speed applications.
6. Power Dissipation: The maximum power dissipation is 625mW. Ensure adequate heat sinking or cooling if operating near this limit to prevent thermal damage.
7. Operating Temperature: The device is rated for operation from -40掳C to 85掳C. Ensure the ambient temperature remains within this range.
8. Storage Temperature: When not in use, store the device between -65掳C and 150掳C to maintain its integrity.

Additional Notes:

• ESD Sensitivity: Handle the SN75451BP with care to avoid electrostatic discharge (ESD), which can damage the device.
• Decoupling Capacitors: Place decoupling capacitors close to the power supply pins to reduce noise and improve stability.
• Grounding: Ensure a good ground connection to minimize interference and improve performance.
