Remarks
The listed voice length is calculated based on a 6 kHz sampling rate. In most practical applications, the sampling rate is typically higher than 8 kHz; therefore, the stated voice length is for reference only.
All IC models support chord playback.
For models other than NV180C, when operated with a 5V power supply, the voice IC must be powered through series-connected 1N4007 or 1N4148 diodes to reduce the operating voltage to approximately 4.5V.
