Abstract

See full text

A combined multiplexer and latch circuit is provided that has only a single gate delay between the input of the overall circuit and the output of the circuit. Two complementary input signal stages each receive a complementary input signal and a multiplexer input. A clocked preset circuit presets a signal at the output of the combined multiplexer and latch circuit with timing based on a first phase of an input clock. A storage circuit stores a value based on the output of the combined multiplexer and latch circuit with timing based on a second phase of the input clock. The circuit has a preset mode during which the output of the combined multiplexer and latch circuit is preset, and has a latch mode during which a value output by the selected complementary signal input stage is output by the circuit and also stored in the storage circuit.
