74LCX574 — Low Voltage Octal D-Type Flip-Flop with 5V Tolerant Inputs and Outputs
DC Electrical Characteristics
AC Electrical Characteristics
Notes:
5. Outputs disabled or 3-STATE only.
6. 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
).
