Instructions for Use:
Supply Voltage (VCC):
- Ensure the supply voltage is within the operating range of 2.0 V to 6.0 V.
- Avoid exceeding the maximum voltage to prevent damage to the device.
Input Voltages (VIL, VIH):
- Input low voltage (VIL) should be between 0.0 V and 0.8 V.
- Input high voltage (VIH) should be between 2.0 V and VCC.
Output Voltages (VOL, VOH):
- Output low voltage (VOL) should not exceed 0.4 V when sourcing 4 mA.
- Output high voltage (VOH) should be at least VCC - 0.4 V when sinking -0.4 mA.
Leakage Currents (IIL, IOL):
- Input leakage current (IIL) and output leakage current (IOL) should be within ±1.0 μA to avoid unwanted behavior.
Propagation Delay Time (tpd):
- The propagation delay time should be no more than 18 ns under typical conditions (VCC = 5 V, TA = 25°C).
Power Dissipation (PD):
- Ensure that the power dissipation does not exceed 100 mW to prevent overheating and potential damage to the device.
Handling and Storage:
- Handle the device with care to avoid static discharge, which can damage sensitive components.
- Store the device in a dry, cool environment to prevent moisture damage.
Circuit Design:
- Use appropriate decoupling capacitors near the power supply pins to reduce noise and improve stability.
- Ensure all inputs are properly terminated to prevent floating states, which can lead to undefined behavior.
Testing:
- Test the device under specified conditions to ensure it meets the required performance parameters.
- Use a reliable test setup to avoid introducing errors during testing.
