Open the CIPO recordAbstract From the Canadian patent
An ECL latch circuit comprises a data input part and a latch part. The data input part includes input transistors coupled in parallel and having bases for respectively receiving an input data and a clock signal, and an output transistor applied with a reference voltage. The data input part samples the input data by the clock signal and outputs a level shifted data signal from a collector of the output transistor. The latch part includes a transistor which has a base for receiving the same clock signal an, emitter coupled transistor pair having bases respectively applied with the reference signal and an output signal of the ECL latch circuit and a transistor, having a base coupled to the …
