4.2 Second LOG-PCM Speech

General Description\nThe HT819D0 is a single chip LOG-PCM voice synthesizer LSI with 4.2-second voice capacity at a 6kHz sampling rate. The chip when triggered drives a speaker through an external transistor with a current switch D/A converter output. Negligible current will be consumed in the stand ? Operating voltage: 2.4V~5.0V\n? Directly drives an external transistor\n? Low standby current (1μA typ. for VDD=3V)\n? Minimal external components\n? 252 words table ROM for key functions\n? Programmable silence length and end-pulse width (minimal end-pulse width is 330μs at a 6kHz sampling rate)\;
