GENERAL DESCRIPTION

The PCF21xxC family are single-chip, silicon gate CMOS

LCD driver circuits. A 3-line bus (CBUS) structure enables

serial data transfer with microcontrollers. All inputs are

CMOS/NMOS compatible.

The devices have the same function and performance as

those of the PCF21xx family, which they supersede.

The maximum operating voltage required is reduced from

6.5 to 6.0 V.
