HT818D0 22.4-Second LOG-PCM Speech

The HT818D0 is a single chip LOG-PCM voice synthesizer LSI with 22.4-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 standby state. The HT818D.
