Switch input, These pins constitute 4-bit general-purpose input port
Data output, Output serial data at falling edge of shift clock, starting from
lower bit. This is N-ch open-drain output pin.
Data input, Inputs serial data at rising edge of shift clock, starting from lower
bit.
Internally connected, Be sure to leave this pin open (this pin is at V
Clock input, Reads serial data at rising edge, and outputs data at falling
edge.
Strobe, Initializes serial interface at rising or falling edge to make
SC16311waiting 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.
Key data input, Data input to these pins is latched at end of display cycle.
Logic power, 5V 10%
High-voltage output (segment), Segment output pins.
High-voltage output (grid/segment), These pins are selectable for segment
or grid output.
Pull-down level, V
High-voltage output (grid), Grid output pins
LED output, CMOS output. +20mV .max.
Logic ground, Connect this pin to GND of system.
Oscillator pin, Connect resistor for determining oscillation frequency to this
pin.
