Instructions for SN74HC166DRG4

1. Power Supply Connections:

   • Connect VCC to the positive supply voltage (2V to 6V).
   • Connect GND to the ground.

2. Input Signals:

   • Ensure input signals meet the specified voltage levels for logic high and low conditions relative to VCC.

3. Output Handling:

   • Outputs can drive up to 4mA when low and sink up to -4mA when high.
   • Use appropriate pull-up or pull-down resistors if necessary.

4. Timing Considerations:

   • Account for propagation delay in timing-sensitive applications.

5. Temperature Range:

   • Operate within the specified temperature range (-40掳C to 85掳C) for reliable performance.
   • Store the device between -65掳C and 150掳C.

6. Handling Precautions:

   • Handle with care to avoid electrostatic discharge (ESD) damage.
   • Follow proper soldering techniques to ensure connections are secure and not damaged by excessive heat.
