Low level logic to high level logic translator having improved high state drive

摘要

A TTL to high level translator having improved high state current drive includes a push-pull output stage and a lateral PNP transistor for supplying current drive when the translator is in a high state. The output stage consists of a pair of Darlington connected transistors comprising an upper amplifier and a lower transistor amplifier connected in series with the upper amplifier. A current transient suppressor circuit circuit is coupled with the bases of the pair of Darlington connected transistors for inhibiting power supply current spikes as the upper and lower amplifiers are alternately turned on and off in response to the TTL logic signal switching between upper and lower level states.
