Instructions for Using 74HC20D

1. Supply Voltage:

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

2. Input Signals:

   • Apply logic low (0) by ensuring the input voltage is below 0.8V.
   • Apply logic high (1) by ensuring the input voltage is above 2.0V.
   • Be aware of the input leakage current, which can be up to 卤1.0 渭A.

3. Output Signals:

   • The output low voltage (V_OL) should not exceed 0.1V when sourcing up to 4 mA.
   • The output high voltage (V_OH) should be at least 2.4V when sinking up to -4 mA.
   • The maximum output sink current (I_OL) is 25 mA, and the maximum output source current (I_OH) is -6 mA.

4. Propagation Delay:

   • The maximum propagation delay time (t_pd) is 18 ns, which affects the speed of signal transmission through the IC.

5. Power Dissipation:

   • The total power dissipation (P_tot) should not exceed 100 mW to avoid overheating and potential damage to the IC.

6. Operating Temperature:

   • The IC is designed to operate within an ambient temperature range of -40掳C to 85掳C.

7. Handling:

   • Handle the IC with care to avoid static discharge, which can damage the sensitive components.
   • Use appropriate anti-static measures when handling and storing the IC.

8. Circuit Design:

   • Ensure proper decoupling capacitors are used near the V_CC and GND pins to stabilize the power supply and reduce noise.
   • Follow good PCB layout practices to minimize signal interference and ensure reliable operation.
