TTL circuit with a clamping transistor for speedy turn-off of output transistor

摘要: A first output transistor, operated in the common emitter mode, has its conduction path connected between an terminal and a point of operating potential. phase splitting transistor whose base is coupled to signal input supplies turn-on current for one value interrupts flow another signal. The discharge residual charge on speedy turn-off accomplished by means clamping collector-to-emitter which turned concurrently with transistor.
