Instructions for Use

1. Supply Voltage:

   • Ensure the supply voltage is within the range of 2.0V to 6.0V. The typical operating voltage is 5V.

2. Input Levels:

   • For a valid low input, the voltage should be less than 0.8V when V_CC is 5V.
   • For a valid high input, the voltage should be greater than 3.5V when V_CC is 5V.

3. Output Levels:

   • When an output is low, it should not exceed 0.25V when sourcing 4mA at V_CC = 5V.
   • When an output is high, it should be at least 4.75V when sinking -0.4mA at V_CC = 5V.

4. Current Handling:

   • Ensure that the input leakage current does not exceed 卤1.0渭A.
   • The output leakage current should not exceed 卤25渭A when the output is low or high.

5. Propagation Delay:

   • The propagation delay time is typically 18ns at V_CC = 5V and T_A = 25掳C.

6. Power Dissipation:

   • The maximum power dissipation is 100mW at V_CC = 5V.

7. Temperature Range:

   • The device can operate within a temperature range of -40掳C to 85掳C.
   • Store the device between -65掳C and 150掳C.

8. Handling:

   • Handle with care to avoid static discharge, which can damage the device.
   • Follow standard ESD (Electrostatic Discharge) precautions.

9. Pin Configuration:

   • Refer to the pinout diagram provided in the datasheet to ensure correct connections.

10. Application Notes:

    • The 74HC154N is a 1-of-16 decoder/demultiplexer. It has 4 address inputs (A, B, C, D) and 16 outputs (Y0 to Y15).
    • The enable inputs (E1, E2) must be low for the device to function. If either enable input is high, all outputs will be high.
    • Only one output will be low at any given time, corresponding to the binary input on A, B, C, and D. All other outputs will be high.
