Instructions for Use
Supply Voltage (VCC):
- Ensure the supply voltage is within the range of 2.0 V to 6.0 V to avoid damage to the device.
Input Voltage Levels:
- For a low input (VIL), the voltage should not exceed 0.8 V.
- For a high input (VIH), the voltage should be at least 2.0 V.
Output Voltage Levels:
- When the output is low (VOL), it should not exceed 0.4 V.
- When the output is high (VOH), it should be at least 2.4 V.
Current Specifications:
- The input leakage current (IIL) should be between -1 μA and 1 μA.
- The output leakage current (IOL) should be between -10 μA and 10 μA.
Propagation Delay Time (tpd):
- The typical propagation delay time at VCC = 5 V and TA = 25°C is 9 ns.
Power Dissipation (PD):
- The maximum power dissipation at continuous operation and TA = 25°C is 100 mW.
Temperature Ranges:
- The operating temperature range (TA) is from -40°C to 85°C.
- The storage temperature range (TSTG) is from -65°C to 150°C.
Handling and Storage:
- Store the device in a dry, cool place to prevent damage from moisture and extreme temperatures.
- Handle with care to avoid static discharge which can damage the device.
Soldering:
- Use appropriate soldering techniques and temperatures to avoid thermal stress on the device.
Circuit Design:
- Ensure proper decoupling capacitors are used near the power supply pins to stabilize the supply voltage and reduce noise.
By following these guidelines, you can ensure reliable and efficient operation of the HD74HC155P.
