Data input, Input serial data at rising edge of shift clock, starting from the low
order bit.
Data output, Output serial data at the falling edge of the shift clock, starting
from low order bit. This is N-ch open-drain output pin.
Strobe, Initializes serial interface at the rising or falling edge of the SC16312. It
then waits for reception of a command. Data input after STB has fallen is
processed as a command. While command data is processed, current
processing is stopped, and the serial interface is initialized. While STB is high,
CLK is ignored.
Clock input, Reads serial data at the rising edge, and outputs data at the falling
edge.
Oscillator pin, Connect resistor to this pin to determine the oscillation frequency
to this pin.
High-voltage output, Segment output pins (Dual function as key source).
High-voltage output (segment), Segment output pins.
High-voltage output (grid), Grid output pins.
High-voltage output (segment/grid), These pins are selectable for segment or
grid driving.
LED output, CMOS output. +20mA max.
Key data input, Data input to these pins is latched at the end of the display
cycle.
Switch input, These pins constitute a 4-bit general-purpose input port.
Logic power, 5 V 10%
Logic ground, Connect this pin to system GND.
Pull-down level, VDD-35V max.
