Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 2.7V to 5.5V.
   • Connect the Vcc pin to the power supply and GND to the ground.

2. Input Signals:

   • Input signals should be within the specified voltage levels:
     • Low level (Vil): 0.8V typical, 1.5V maximum.
     • High level (Vih): 3.5V minimum, 4.2V typical.

3. Output Signals:

   • The output can source up to 10mA at high level and sink up to 10mA at low level.
   • Ensure the load connected to the output does not exceed these current limits.

4. Propagation Delay:

   • The typical propagation delay time (tpd) is 10ns at Vcc = 5V and ambient temperature (Ta) = 25掳C.
   • Consider this delay when designing timing-critical applications.

5. Temperature Considerations:

   • The operating temperature range (Topr) is from -40掳C to 85掳C.
   • The storage temperature range (Tstg) is from -65掳C to 150掳C.
   • Ensure the device is not exposed to temperatures outside these ranges during operation or storage.

6. Handling Precautions:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Follow proper soldering techniques to prevent thermal damage during assembly.

7. Mounting and Layout:

   • Ensure proper PCB layout to minimize noise and interference.
   • Place decoupling capacitors close to the Vcc and GND pins to stabilize the power supply.

8. Testing and Verification:

   • Verify the functionality of the device using a known good test circuit.
   • Monitor the supply voltage and output currents to ensure they are within the specified limits.
