Instructions for Use:

Power Supply:
- Ensure the supply voltage (Vcc) is within the specified range of 4.5V to 5.5V.
- Connect the Vcc pin to a stable power source and GND to the ground.
Output Configuration:
- The device can drive up to 100mA per channel. Ensure the load does not exceed this limit to avoid damage.
- For optimal performance, use appropriate pull-up or pull-down resistors on the output lines if necessary.
Temperature Considerations:
- Operate the device within the temperature range of -40°C to 125°C.
- Store the device in an environment with temperatures ranging from -65°C to 150°C.
Current Consumption:
- The quiescent current (Iq) is typically between 1mA and 3mA. Design the power supply to accommodate this consumption.
Output Levels:
- When the output is low, the voltage should not exceed 0.4V.
- When the output is high, the voltage should be at least 4.5V.
Timing Parameters:
- The propagation delay time (tPD) is typically 100ns.
- The rise time (tr) and fall time (tf) are both typically 25ns. Ensure your system design accounts for these timing parameters to avoid signal integrity issues.
Handling and Storage:
- Handle the device with care to avoid static discharge, which can damage the internal components.
- Store the device in a dry, cool place to prevent moisture damage.
PCB Layout:
- Place the device close to the load to minimize trace lengths and reduce noise.
- Use decoupling capacitors (typically 0.1μF) near the power pins to filter out high-frequency noise.

By following these guidelines, you can ensure reliable and efficient operation of the TL2844DRE4.
