Data input pin. Input serial data at rising edge of shift clock, starting from the low order bit.
Data output pin. 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 pin. Initializes serial interface at the rising or falling edge of the SC16315. 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 pin. Reads serial data at the rising edge, and outputs data at the falling edge.
Oscillator pin. Determine the oscillation frequency by the resistor connecting this pin and GND (VSS).
High-voltage output (segment). Segment output pins (Dual function as key source).
High-voltage output (grid). Grid output pins.
High-voltage output (segment/grid). Segment or grid driving.
LED output pin. CMOS output. +20mA max.
Key data input. Data input to these pins is latched at the end of the display cycle.
Logic power pin. 5V±10%
Logic ground. Connect this pin to system GND.
Pull-down level. VDD-35V max.
