Instructions for Use:
Power Supply:
- Ensure the supply voltage (VCC) is within the range of 2.0V to 6.0V.
- Connect the ground (GND) pin to the system ground.
Input Signals:
- Apply input voltages (VIH and VIL) that meet the specified thresholds.
- For VCC = 4.5V to 5.5V, VIH should be at least 3.15V, and VIL should not exceed 1.35V.
Output Signals:
- The output voltage (VOH) will be close to VCC when high, with a maximum drop of 0.4V under a load of -4mA.
- The output voltage (VOL) will be close to 0V when low, with a maximum rise of 0.4V under a load of 4mA.
Propagation Delay:
- The typical propagation delay time (tpd) is 18ns at VCC = 5V and ambient temperature (TA) = 25°C.
Power Consumption:
- The device typically consumes 20mW of power at VCC = 5V and a frequency (f) of 10MHz.
Handling Precautions:
- Handle the 74HC4851 with care to avoid static discharge, which can damage the device.
- Ensure all connections are secure and free from shorts or open circuits.
Operating Temperature:
- The device is designed to operate within a temperature range of -40°C to +85°C.
Storage and Transportation:
- Store the device in a dry, cool place to prevent moisture damage.
- Follow ESD (Electrostatic Discharge) guidelines during transportation and handling.
