TM1624 from TM Shenzhen Titan Micro Elec, in a SOIC-24-300mil. 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 DIN bidirectional Serial data input (DIO). Data is shifted in LSB-first on the rising edge of CLK; data is output on the falling edge (chip supports read-back, hence bidirectional).
2 CLK input Serial clock input. Data is read on rising edges; output data is driven on falling edges. Ignored while STB is high.
3 STB input Chip-select / strobe. A rising or falling edge initializes the serial interface; the first byte after STB goes low is treated as a command. Driving STB high aborts the current transaction and forces CLK to be ignored.
4 VDD power_in Logic supply, 5 V ±10%.
5 SEG1 output Segment output 1, P-channel open-drain. Connects to the anode of a common-cathode LED segment (must never be tied to a cathode).
6 SEG2 output Segment output 2, P-channel open-drain LED-anode driver.
7 SEG3 output Segment output 3, P-channel open-drain LED-anode driver.
8 SEG4 output Segment output 4, P-channel open-drain LED-anode driver.
9 SEG5 output Segment output 5, P-channel open-drain LED-anode driver.
10 SEG6 output Segment output 6, P-channel open-drain LED-anode driver.
11 SEG7 output Segment output 7, P-channel open-drain LED-anode driver.
12 SEG8 output Segment output 8, P-channel open-drain LED-anode driver.
13 SEG9 output Segment output 9, P-channel open-drain LED-anode driver.
14 SEG10 output Segment output 10, P-channel open-drain LED-anode driver.
15 SEG11 output Segment output 11, P-channel open-drain LED-anode driver.
16 SEG12/GRID7 output Muxed segment/grid output. Acts as SEG12 (P-channel open-drain anode driver) in modes with fewer digits, and as GRID7 (N-channel open-drain cathode/common driver) in the 7-digit x 11-segment mode.
17 SEG13/GRID6 output Muxed segment/grid output. Acts as SEG13 in 4-5 digit modes and as GRID6 (N-channel open-drain) in 6- and 7-digit modes.
18 SEG14/GRID5 output Muxed segment/grid output. Acts as SEG14 in 4-digit mode and as GRID5 (N-channel open-drain) in 5-, 6- and 7-digit modes.
19 GND power_in Logic ground. Tie to system ground; both GND pins (19 and 22) must be connected.
20 GRID4 output Digit/grid output 4, N-channel open-drain. Connects to the common cathode of digit 4 (must never be tied to an anode).
21 GRID3 output Digit/grid output 3, N-channel open-drain common-cathode driver.
22 GND power_in Logic ground. Second GND pin; tie together with pin 19 to system ground.
23 GRID2 output Digit/grid output 2, N-channel open-drain common-cathode driver.
24 GRID1 output Digit/grid output 1, N-channel open-drain common-cathode driver.
