Instructions for Use:
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 2.0 V to 6.0 V.
- Connect the ground (GND) pin to the system ground.
Input Signals:
- Apply input signals (VIN) that are within the specified input voltage ranges.
- For logic high, ensure VIN ≥ 3.15 V when VCC = 4.5 V.
- For logic low, ensure VIN ≤ 1.35 V when VCC = 4.5 V.
Output Signals:
- The output voltage (VOH) will be at least 2.4 V when the output is high and the load current (IO) is -0.4 mA.
- The output voltage (VOL) will be no more than 0.4 V when the output is low and the load current (IO) is 8 mA.
Propagation Delay:
- The propagation delay time (tpd) is the time it takes for the output to change state after the input changes. It is typically 11 ns at VCC = 4.5 V and TA = 25°C.
Temperature Considerations:
- The device can operate within a temperature range of -40°C to 85°C.
- Store the device in temperatures ranging from -65°C to 150°C.
Power Dissipation:
- Ensure that the power dissipation does not exceed 100 mW to avoid overheating and potential damage to the device.
Handling:
- Handle the device with care to avoid static discharge, which can damage the internal circuits.
- Follow standard ESD (Electrostatic Discharge) precautions when handling the device.
