Instructions for Using SN74HCT273DWR

1. Power Supply:

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

2. Input Signals:

   • Apply input signals (V_IL, V_IH) within the specified voltage ranges to avoid damage or incorrect operation.
   • V_IL should be between 0.0 V and 0.8 V.
   • V_IH should be between 2.0 V and V_CC.

3. Output Signals:

   • The output low voltage (V_OL) will be between 0.0 V and 0.4 V when sourcing 4 mA.
   • The output high voltage (V_OH) will be between 2.4 V and V_CC when sinking -0.4 mA.

4. Propagation Delay:

   • The propagation delay time (t_pd) is typically 12 ns at V_CC = 5 V and T_A = 25°C.

5. Power Dissipation:

   • Ensure the total power dissipation (P_D) does not exceed 350 mW to prevent overheating.

6. Temperature Ranges:

   • Operate the device within the temperature range of -40°C to 85°C.
   • Store the device within the temperature range of -65°C to 150°C.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Use proper ESD protection measures during handling and assembly.

8. Application Notes:

   • Refer to the datasheet for detailed application notes and circuit diagrams.
   • Ensure all unused inputs are tied to either V_CC or GND to prevent floating states.

By following these instructions, you can ensure reliable and efficient operation of the SN74HCT273DWR.
