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.

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.
