Instructions for Using HD74154P
Supply Voltage:
- Ensure the supply voltage (VCC) is within the range of 4.5V to 5.5V to avoid damage to the IC.
Input Levels:
- For a valid low input (VIL), the voltage should be between 0V and 0.8V.
- For a valid high input (VIH), the voltage should be between 2.0V and VCC.
Output Levels:
- When the output is low (VOL), the voltage should not exceed 0.4V when sourcing 4.0 mA.
- When the output is high (VOH), the voltage should be at least 2.4V when sinking 0.4 mA.
Current Ratings:
- The input leakage current (IIL) should be within ±1.0 μA.
- The output leakage current (IOL (High)) should be within ±0.1 μA.
- The output can sink up to 4.0 mA when low (IOL (Low)).
Propagation Delay:
- The propagation delay time (tpd) is typically 50 ns at a supply voltage of 5V and a frequency of 1 MHz.
Power Dissipation:
- The maximum power dissipation (PD) is 100 mW. Ensure proper heat dissipation if operating near this limit.
Handling and Storage:
- Handle the IC with care to avoid static damage. Store in a dry, cool place away from direct sunlight.
Pin Configuration:
- Refer to the datasheet for the specific pin configuration and function of each pin.
Application Notes:
- The HD74154P is a 1-of-16 decoder/demultiplexer. It can be used to decode a 4-bit binary input into one of 16 active-low outputs. Ensure that the enable inputs are correctly set to activate the decoding function.
