Connected to Functions

VLCD pin/booster Potential difference between Vci and GND is boosted

capacitance twice or three times and then output. Magnitude of

boost is selected by instruction.

Booster

capacitance

External capacitance should be connected here when

using the double or triple booster.

Booster

capacitance

External capacitance should be connected here when

using the triple booster. Must be left disconnected

only when using the double booster.

MPU or external Reset pin. Initializes the LSI when low.

R-C circuit

Must reset after power-on.

VCC or GND

Turns the internal operational amplifier off when

OPOFF = VCC, and turns it on when OPOFF = GND.

If the amplifier is turned off (OPOFF = VCC), V1 to V5

must be supplied to the V1OUT to V5OUT pins.

Input pins

Input pins

Outputs the internal VCC level; shorting this pin sets

the adjacent input pin to the VCC level.

Outputs the internal GND level; shorting this pin sets

the adjacent input pin to the GND level.

GND

Test pin. Must be fixed at GND level.

—

Test pins. Must be left disconnected.
