PECL output is disabled and complementary output remains high
when Tristate pin is HIGH. Both PECL and complementary PECL
outputs are high when Tristate pin is LOW.

This describes HP64 package PECL, + 5.0Volt supply, ± 25ppm over 0°to
+ 70°C, at frequency of 125.0MHz.
Note: For non-standard frequency stability for commercial temperature
range use the Code’C’ followed by the stability, example ‘C20’ for
± 20ppm over 0° to + 70°C. For industrial temperature range use ‘I’
and the stability, example ‘I20’ for ± 20ppm over -40° to + 85°C.
