74HC/HCT4067; 16-channel Analog Multiplexer/demultiplexer;; Package: SOT101-1 (DIP24), SOT137 (SO24), SOT340-1 (SSOP24), SOT355-1 (TSSOP24)

Instructions for Using the 74HC4067 Multiplexer/Demultiplexer:

1. Power Supply:

   • Connect the V_CC pin to the positive supply voltage (2.0V to 6.0V).
   • Connect the GND pin to the ground.

2. Control Inputs:

   • The 74HC4067 has four control inputs (S0, S1, S2, S3) that select one of the 16 channels.
   • The channel selection is determined by the binary value of S0, S1, S2, and S3.

3. Channel Selection:

   • The channel number is calculated as follows:
     • Channel Number = (S3 * 8) + (S2 * 4) + (S1 * 2) + S0
   • For example, to select channel 5, set S0 = 1, S1 = 0, S2 = 1, S3 = 0.

4. Signal Routing:

   • In multiplexer mode, the selected input channel is connected to the common output (COM).
   • In demultiplexer mode, the common input (COM) is connected to the selected output channel.

5. Propagation Delay:

   • The propagation delay time (t_pd) is the time it takes for a signal to travel from the input to the output. It typically ranges from 10 to 30 nanoseconds at V_CC = 4.5V to 5.5V.

6. Power Consumption:

   • The power consumption is relatively low, with a maximum of 10 mW at V_CC = 4.5V to 5.5V.

7. Operating Temperature:

   • The device is designed to operate over a temperature range of -40°C to 85°C.

8. Handling Precautions:

   • Handle the IC with care to avoid static damage.
   • Ensure all connections are secure and correct to prevent damage to the device.

9. Applications:

   • The 74HC4067 is suitable for applications requiring multiple input/output switching, such as data acquisition systems, sensor interfacing, and digital signal routing.
