GN Semic · LED Drivers · DIP-16

GN1650D from GN Semic, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DIG1 output LED digit-drive output, active low, which also serves as the keyboard-scan output (active high).
2 CLK input Clock input for the two-wire serial interface, with an internal pull-up resistor.
3 DIO bidirectional Data input/output for the two-wire serial interface, implemented as an internal pull-up open-drain.
4 GND power_in Ground.
5 DIG2 output LED digit-drive output, active low, which also serves as the keyboard-scan output (active high).
6 DIG3 output LED digit-drive output, active low, which also serves as the keyboard-scan output (active high).
7 DIG4 output LED digit-drive output, active low, which also serves as the keyboard-scan output (active high).
8 A/KI1 bidirectional LED segment-A drive output (active high) that also serves as keyboard-scan input KI1 (active high), with an internal pull-down.
9 B/KI2 bidirectional LED segment-B drive output (active high) that also serves as keyboard-scan input KI2 (active high), with an internal pull-down.
10 VDD power_in Supply pin, 3 V to 5.5 V; a 104 decoupling capacitor should be placed to ground as close as possible to the pin (under 2 cm).
11 C/KI3 bidirectional LED segment-C drive output (active high) that also serves as keyboard-scan input KI3 (active high), with an internal pull-down.
12 D/KI4 bidirectional LED segment-D drive output (active high) that also serves as keyboard-scan input KI4 (active high), with an internal pull-down.
13 E/KI5 bidirectional LED segment-E drive output (active high) that also serves as keyboard-scan input KI5 (active high), with an internal pull-down.
14 F/KI6 bidirectional LED segment-F drive output (active high) that also serves as keyboard-scan input KI6 (active high), with an internal pull-down.
15 G/KI7 bidirectional LED segment-G drive output (active high) that also serves as keyboard-scan input KI7 (active high), with an internal pull-down.
16 DP/KP output LED decimal-point segment output that also serves as the keyboard-flag output.
