Emitter Coupled Logic

Emitter Coupled Logic

(ECL) (Or "Current Mode Logic") A technology for building logic gates where the emitter of a transistor is used as the output rather than its collector. ECL has a propagation time of 0.5 - 2 ns (faster than TTL) and a power dissipation 3 - 10 times higher than TTL.
