74LCX373 Low Voltage Octal Transparent Latch with 5V Tolerant Inputs and Outputs
Absolute Maximum Ratings
The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are
not guaranteed at the Absolute Maximum Ratings. The “Recommended Operating Conditions” table will define the
conditions for actual device operation.

Notes:
6. Outputs disabled or 3-STATE only.
7. 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, either HIGH-to-LOW (t
OSHL
) or
LOW-to-HIGH (t
OSLH
).
