Q & A
- What is the operating voltage range of the MC74HC373ADWR2G?
The operating voltage range is 2.0 to 6.0 V.
- What is the maximum propagation delay from input D to Q?
The maximum propagation delay ranges from 21 to 190 ns, depending on the supply voltage.
- Can the MC74HC373ADWR2G interface directly with TTL outputs?
- What is the input current of the MC74HC373ADWR2G?
The low input current is 1.0 μA.
- Is the MC74HC373ADWR2G RoHS compliant?
- What is the chip complexity of the MC74HC373ADWR2G?
The chip complexity is 196 FETs or 49 equivalent gates.
- What is the purpose of the Latch Enable input?
