Power Supply:
- Ensure the supply voltage (V_CC) is within the range of 2.0V to 6.0V.
- Connect the ground (GND) pin to a stable reference ground.
Input Signals:
- Apply input signals (D0-D7) that meet the specified high (V_IH) and low (V_IL) voltage levels.
- Ensure input currents do not exceed ±1μA to avoid damaging the device.
Output Signals:
- The output pins (Q0-Q7) can source or sink up to 400μA.
- Ensure the load connected to the output pins does not exceed the maximum current ratings.
Control Signals:
- Use the latch enable (LE) signal to control when data is latched from the input to the output.
- When LE is high, the outputs follow the inputs.
- When LE is low, the outputs hold the last latched data.
Propagation Delay:
- The propagation delay time (t_pd) is typically 10ns at 4.5V and 25°C.
- Ensure your timing design accounts for this delay to avoid race conditions.
Temperature Considerations:
- Operate the device within the commercial temperature range of 0°C to 70°C.
- Store the device in the extended temperature range of -40°C to 125°C.
Power Dissipation:
- The maximum power dissipation is 100mW. Ensure proper heat sinking if operating near this limit.
Handling Precautions:
- Handle the device with care to avoid static damage.
- Follow proper ESD (Electrostatic Discharge) handling procedures.

By following these guidelines, you can ensure reliable operation of the HD74HC373P in your circuit.
