Notes: (1) Caution: Stresses listed under “Absolute Maximum Ratings” may be applied to devices one at a time without causing perma-
nent damage. Functionality at or exceeding the values listed is not implied. Exposure to these values for extended periods may
affect device reliability.
(2) VTT must be applied before any input signal voltage magnitude (VECLIN and VHSIN) can be greater than VTT -0.5V.
(3) Lower limit of specification is ambient temperature and upper limit is case temperature.
(4) When using internal ECL 100K reference level.
ESD Ratings
Proper ESD procedures should be used when handling this product. The VSC8021/VSC8022 is rated to the fol-
lowing ESD voltages based on the human body model:
1. All ECL pins are rated at or above 1000V.
2. All high-speed clock and data pins at rated at or above 500V.
