Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage ( V_ ) is within the specified range (up to 18V). The CD4049 can operate from a single supply or dual supplies.

2. Input Signals:

   • Inputs should be kept within the logic levels defined by ( V_ ) and ( VIH ). For reliable operation, input signals should not exceed the supply voltage ( V_ ).

3. Output Loads:

   • Outputs are designed to drive TTL, CMOS, and other similar logic families. Ensure current ratings do not exceed the maximum specified limits to avoid damage.

4. Propagation Delay:

   • Consider the propagation delay ( t_ ) in timing-sensitive applications. This parameter affects the speed at which the output responds to changes in the input.

5. Thermal Management:

   • Keep the device within its operating temperature range (-40°C to 85°C). Exceeding these temperatures can lead to unreliable operation or damage.

6. Handling Precautions:

   • The CD4049 is sensitive to electrostatic discharge (ESD). Handle with appropriate ESD precautions to prevent damage.

7. Mounting and Layout:

   • Follow recommended PCB layout guidelines to minimize noise and ensure optimal performance. Proper decoupling capacitors near the power pins are advised.
