MC74VHC1G50,
MC74VHC1GT50
The MC74VHC1G50 / MC74VHC1GT50 is an advanced high
speed CMOS buffer in tiny footprint packages. The MC74VHC1G50
has CMOS level input thresholds while the MC74VHC1GT50 has
TTL level input thresholds.
The input structures provide protection when voltages up to 5.5 V
are applied, regardless of the supply voltage. This allows the device to
be used to interface 5 V circuits to 3 V circuits. Some output structures
also provide protection when VCC = 0 V and when the output voltage
exceeds VCC. These input and output structures help prevent device
destruction caused by supply voltage − input/output voltage mismatch,
battery backup, hot insertion, etc.

5. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC. CPD is used to determine the no−load dynamic
power consumption; PD = CPD VCC2 fin + ICC VCC.
