Instructions for Use:

1. Power Supply:

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

2. Input Signals:

   • Apply input signals (e.g., clock, reset, preset) with voltages within the specified ranges.
   • Ensure that the input high voltage (V_IH) is at least 3.15V and the input low voltage (V_IL) is no more than 0.85V.

3. Output Signals:

   • The output high voltage (V_OH) will be close to V_CC when the output is high.
   • The output low voltage (V_OL) will be close to 0V when the output is low.

4. Propagation Delays:

   • The typical propagation delay time (t_pd) is 19ns at V_CC = 5V.
   • The maximum propagation delay time (t_pd(max)) is 22ns at V_CC = 4.5V to 5.5V.

5. Clock-to-Q Output Change Time:

   • The typical clock-to-Q output change time (t_cc) is 18ns at V_CC = 5V.
   • The maximum clock-to-Q output change time (t_cc(max)) is 22ns at V_CC = 4.5V to 5.5V.

6. Setup and Hold Times:

   • Ensure that the setup time (t_setup) is at least 15ns and the hold time (t_hold) is at least 6ns at V_CC = 5V.

7. Supply Current:

   • The typical supply current (I_CC) is 1渭A, with a maximum of 20渭A when all inputs and outputs are at V_CC/2.

8. Handling and Storage:

   • Handle the device with care to avoid electrostatic discharge (ESD) damage.
   • Store the device in a dry, cool environment to prevent moisture damage.

9. Pin Configuration:

   • Refer to the datasheet for the specific pin configuration and connections.

10. Testing and Verification:

    • Verify the functionality of the device using a logic analyzer or oscilloscope to check the timing parameters and signal levels.

For detailed information and further specifications, refer to the official datasheet of the MM74HC161N.
