This is a CMOS based serial to parallel converter IC with dual mode for positive and negative voltage outputs. It comprises of a 32-bit register and provides the functionality to choose between 6/8-bit output words. Positive and digital mode is selected with the help of a MUX. The chip has an on-chip LDO for +5V to +3V conversion and a negative voltage generation block with on-chip oscillator. During power-saver mode, the oscillator frequency is reduced drastically to sustain negative voltage at No Load condition.
