Pin Description Pin No 6 5 Symbol DIN DOUT Pin Name Date input Date output Description Input serial data at rising edge of shift clock, starting from lower bit. Outputs serial data at falling edge of shift clock, starting from lower bit. This is N-ch open-drain output pin. Initializes serial interface at rising or falling edge to make TP6311 waiting for reception of command. Data input after STB has fallen is processed as command. While command data is processed, current processing is stopped, and serial interface is initialized. While STB is high, CLK is ignored. Reads serial data at rising edge, and outputs data at falling edge. Connect resistor for determining oscillation frequency to this pin. Segment output pins (Dual function as key source) Grid output pins These pins are selectable for segment or grid output. CMOS output. +20 mA max Data input to these pins is latched at end of display cycle. These pins constitute 4-bit general-purpose input port. 5V ¡Ó 10% Connect this pin to GND of system.
