TM1617 from TM Shenzhen Titan Micro Elec, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DIO tri_state Serial data input on clock rising edge from LSB and output on falling edge from LSB; N-channel open-drain output requiring external 1K-10K pull-up resistor.
2 CLK input Serial clock input that reads data on rising edge and outputs data on falling edge.
3 STB input Chip select input that initializes serial interface on rising or falling edge; first byte after STB goes low acts as command; CLK is ignored when STB is high.
4 K1 input Keyboard scan data input; data is latched after display cycle ends.
5 VDD power_in Logic power supply; 5V±10% nominal voltage.
6 SEG5 output Segment output (alternate function KS5 for keyboard scan); P-channel open-drain output.
7 SEG6 output Segment output (alternate function KS6 for keyboard scan); P-channel open-drain output.
8 SEG7 output Segment output (alternate function KS7 for keyboard scan); P-channel open-drain output.
9 SEG8 output Segment output (alternate function KS8 for keyboard scan); P-channel open-drain output.
10 SEG9 output Segment output (alternate function KS9 for keyboard scan); P-channel open-drain output.
11 SEG10 output Segment output (alternate function KS10 for keyboard scan); P-channel open-drain output.
12 SEG11 output Segment output; P-channel open-drain output.
13 SEG12 output Segment/Grid multiplex output; can only be configured as segment or grid output.
14 GND power_in Logic ground; connects to system ground.
15 GRID2 output Grid output for digit selection; N-channel open-drain output.
16 GRID1 output Grid output for digit selection; N-channel open-drain output.
