Test

NOTE: The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its transmission line effects

must be taken into account. A transmission line with a delay of 2 ns or longer can be used to produce the desired transmission line effect.

The transmission line is intended as a load only. It is not necessary to add or subtract the transmission line delay (2 ns or longer) from

the data sheet timings.

Device Pin

(see note)

Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the device pin.
