Instructions for Using HD74182P
Power Supply:
- Ensure the power supply voltage (Vcc) is within the specified range of 4.5V to 5.5V.
- Connect the ground (GND) pin to a stable reference ground.
Input Signals:
- Apply input signals (A, B, C, D) with voltages within the specified levels:
- High level (VIH): ≥ 2.0V
- Low level (VIL): ≤ 0.8V
- Ensure the input currents do not exceed the maximum limits:
- IIH: 1.0 μA to 20 μA
- IIL: -1000 μA to -10 μA
- Apply input signals (A, B, C, D) with voltages within the specified levels:
Output Signals:
- The output signals (S, C) will be:
- High level (VOH): ≥ 2.4V
- Low level (VOL): ≤ 0.4V
- Ensure the output currents do not exceed the maximum limits:
- IOH: up to 400 μA (source)
- IOL: up to 400 μA (sink)
- The output signals (S, C) will be:
Propagation Delay:
- The propagation delay time (tpd) from input to output should be considered in the design, typically ranging from 16 to 32 nanoseconds.
Power Dissipation:
- Ensure the total power dissipation (PD) does not exceed 100 mW to avoid overheating and potential damage to the device.
Handling and Storage:
- Handle the device with care to avoid static discharge and physical damage.
- Store the device in a dry, cool place away from direct sunlight and sources of heat.
Testing and Verification:
- Test the device using a known good circuit to verify its functionality.
- Use appropriate test equipment to measure input and output voltages and currents.
By following these parameters and instructions, you can ensure reliable operation of the HD74182P in your circuits.
