TERMINAL FUNCTIONS

TERMINAL

NAME

PWP

I/O

DESCRIPTION

Blank (all constant-current outputs off). When BLANK is high, all constant-current outputs (OUT0 through

OUT15) are forced off, the Grayscale PWM timing controller initializes and the Grayscale counter resets

BLANK

to '0'. When BLANK is low, all constant-current outputs are controlled by the Grayscale PWM timing

controller.

I

Reference clock for Grayscale PWM control.

This pin sets the constant-current value. OUT0 through OUT15 sink constant-current is set to desired

value by connecting an external resistor between IREF and GND.

Input mode pin. When MODE is high, the input mode is dot correction (DC). When MODE is low, the

input mode is grayscale (GS).
