Additional preview pages of the HT814D0 datasheet.

The HT814D0 is a single chip LOG-PCM voice synthesizer LSI with 8.4-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.

Operating voltage: 2.4V~5.0V Directly drives an external transistor Low standby current (1mA typ. for VDD=3V) Minimal external components 508 words table ROM for key functions Programmable silence length and end-pulse width (minimal end-pulse width is 330ms at a 6kHz sampling rate) 8.4-second voice capacity (based on a 6kHz sampling rate) 12 keys Controllable volume FLAG1 options - End-pulse output - 3HzB flash - 6HzB flash - Voice out.
