Instructions for Use

1. Power Supply:

   • Connect the VDD pin to the positive supply voltage (2.7V to 5.5V).
   • Connect the VSS pin to ground.

2. Channel Selection:

   • Use the address inputs (A0, A1, A2) to select the desired channel.
   • The channel selection is binary-coded:
     • A0 = 0, A1 = 0, A2 = 0 selects Channel 0
     • A0 = 1, A1 = 0, A2 = 0 selects Channel 1
     • A0 = 0, A1 = 1, A2 = 0 selects Channel 2
     • A0 = 1, A1 = 1, A2 = 0 selects Channel 3
     • A0 = 0, A1 = 0, A2 = 1 selects Channel 4
     • A0 = 1, A1 = 0, A2 = 1 selects Channel 5
     • A0 = 0, A1 = 1, A2 = 1 selects Channel 6
     • A0 = 1, A1 = 1, A2 = 1 selects Channel 7

3. Enable Pin (EN):

   • Set the EN pin to low (0V) to enable the multiplexer/demultiplexer.
   • Set the EN pin to high (VDD) to disable the device, placing all channels in a high-impedance state.

4. Signal Routing:

   • In multiplexer mode, connect the common input/output (Y) to the signal source.
   • In demultiplexer mode, connect the common input/output (Y) to the load or output device.
   • The selected channel will route the signal from/to the common input/output (Y).

5. Handling Precautions:

   • Ensure that the supply voltage is within the specified range to avoid damage.
   • Avoid exceeding the maximum input/output voltage to prevent device failure.
   • Store the device in a dry environment within the specified storage temperature range.

6. Testing:

   • Verify the functionality by applying a known signal to the input and measuring the output on the selected channel.
   • Check the off-state leakage current to ensure proper isolation between channels.

7. Layout Considerations:

   • Place decoupling capacitors close to the power pins to minimize noise and ensure stable operation.
   • Keep signal traces short to reduce parasitic capacitance and inductance.
