Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be

operable above the recommended operating conditions and stressing the parts to these levels is not recommended.

In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.

The absolute maximum ratings are stress ratings only.

Note:

Recommended Operating Conditions

The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended

operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not

recommend exceeding them or designing to absolute maximum ratings.

3. Applies to bushold versions only (74LVTH374).

4. An external driver must source at least the specified current to switch from LOW-to-HIGH.

5. An external driver must sink at least the specified current to switch from HIGH-to-LOW.

6. This is the increase in supply current for each input that is at the specified voltage level rather than V
