Pin Name
Description
Data input
Inputs serial data at rising edge of shift clock, starting from lower
bit.
Data output
Outputs serial data at falling edge of shift clock, starting from
lower bit. This is N-ch open-drain output pin.
Strobe
Initializes serial interface at rising or falling edge to make
PD16311 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.
Clock input
Reads serial data at rising edge, and outputs data at falling edge.
Oscillator pin
Connect resistor for determining oscillation frequency to this pin.
High-voltage output
(segment)
Segment output pins (Dual function as key source)
High-voltage output (grid) Grid output pins
High-voltage output
(segment/grid)
These pins are selectable for segment or grid output.
LED output
CMOS output. +20 mA max.
Key data input
Data input to these pins is latched at end of display cycle.
Switch input
Logic power
These pins constitute 4-bit general-purpose input port.
5 V  10 %
Logic ground
Pull-down level
Connect this pin to GND of system.
VDD  35 V max.
Internally connected
Be sure to leave this pin open (this pin is at VDD level).
