Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.0V to 6.0V.
   • Connect the ground (GND) pin to the system ground.

2. Input Signals:

   • Input signals should be within the specified input low (V_IL) and high (V_IH) voltage ranges.
   • Avoid exceeding the maximum input voltage (V_CC).

3. Output Signals:

   • The output low voltage (V_OL) should not exceed 0.1V when sourcing 4mA.
   • The output high voltage (V_OH) should be at least V_CC - 0.1V when sinking 4mA.

4. Propagation Delay:

   • The typical propagation delay time (t_pd) is 12ns at V_CC = 5V and T_A = 25掳C.
   • Ensure that the system design accounts for this delay to avoid timing issues.

5. Power Dissipation:

   • The maximum power dissipation (P_D) is 500mW. Ensure proper heat dissipation to prevent overheating.

6. Temperature Ranges:

   • The operating temperature range (T_A) is from -40掳C to 85掳C.
   • The storage temperature range (T_STG) is from -65掳C to 150掳C.

7. Handling and Storage:

   • Handle the device with care to avoid static damage.
   • Store the device in a dry environment within the specified storage temperature range.

8. Mounting:

   • Follow standard surface mount technology (SMT) guidelines for mounting the device on the PCB.
   • Ensure proper soldering to all pins to avoid poor electrical connections.
