Test

NOTE: The data manual 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 manual timings.

Device Pin

(see note)

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

pin.

ESD Performance

ESD stress levels were performed in compliance with the following JEDEC standards with the results indicated

below:

•

Charged Device Model (CDM), based on JEDEC Specification JESD22-C101, passed at

±500 V

•

Human Body Model (HBM), based on JEDEC Specification JESD22-A114, passed at

±1500 V

NOTE:

According to industry research publications, ESD-CDM testing results show better correlation

to manufacturing line and field failure rates than ESD-HBM testing. 500-V CDM is commonly

considered as a safe passing level.

Timing Parameter Symbology

Timing parameter symbols used in the timing requirements and switching characteristics tables are created

in accordance with JEDEC Standard 100. To shorten the symbols, some of the pin names and other related

terminology have been abbreviated as follows:
