The D - flip-flop is triggered on the falling edge of the clock. The SK1900 uses standard open emitter ECL outputs optimized for:

It is also capable of receiving inputs of any technology or voltage level. The D - flip-flop is triggered on the falling edge of the clock. The SK1925 has open emitter PECL outputs. Target applications:  High speed clock / data lines that require translation  Multiple destination (daisy chain)

It is also capable of receiving inputs of any technology or voltage level. The D - flip-flop is triggered on the falling edge of the clock. The SK1926 has standard open emitter ECL outputs.
