An improved driver interface circuit for interfacing between low voltage, low drive capability logic signals and large capacitive loads requiring high speed, high voltage logic signals. The improvement comprising the use of the logic input signal to power gate a high level buffer contained in the driver and thereby minimize the power consumption during inactive periods.

Low power, high level driver

Speech compaction/replay apparatus for real time monitoring speech and filtering out periods of relative slence from a recording of the speech. The recording also containing synchronization and time code information for ensuring that on replay and in terms of real time the audio output will essentially replicates the analog speech input. The apparatus and technique minimizing the amount of storage media required to store the speech.
