74LVT240, 74LVTH240 Rev. 1.5.0

5

Notes:

7. Characterized in SOIC package. Guaranteed parameter, but not tested.

8. Max number of outputs defined as (n). n–1 data inputs are driven 0V to 3V. Output under test held LOW.

AC Electrical Characteristics

Notes:

10. Skew is defined as the absolute value of the difference between the actual propagation delay for any two

separate outputs of the same device. The specification applies to any outputs switching in the same direction,

Note:

11. Capacitance is measured at frequency f

= 1MHz, per MIL-STD-883, Method 3012.
