<p>An emitter coupled logic circuit includes a bypass circuit which provides a conductive path for current when a programmable fuse is blown, so that input data is transmitted independently of the state of a clock signal. In one implementation, the circuit takes a register configuration having a master section and a slave section, each incorporating a programmable fuse. When the fuse in just one section is intact, the circuit serves as a clocked latch. When both fuses are blown, the bypass circuit is enabled so that the register functions as a combinatorial circuit which produces an output signal dependent on the input signal without reference to a clock signal.</p> |
