STP04CM05XTTR from STMicroelectronics, in a HTSSOP-16-EP. 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 | GND | power_in | Ground terminal; the datasheet rates the GND terminal current at 2000 mA absolute maximum. |
| 2 | GND | power_in | Ground terminal; the datasheet rates the GND terminal current at 2000 mA absolute maximum. |
| 3 | SDI | input | Serial data input terminal; logic high requires at least 0.7 VDD and logic low must stay at or below 0.3 VDD, with absolute input range -0.4 V to VDD+0.4 V. |
| 4 | CLK | input | Clock input terminal for the 4-bit serial-in shift register, rated up to 30 MHz in cascade operation. |
| 5 | LE | input | Latch input terminal; when high the latch refreshes its data from the SDI chain, and when low it holds the previous data set. |
| 6 | OUT 0 | output | Constant-current output channel 0, 80 to 400 mA per channel set by R-EXT, with 20 V output driving capability. |
| 7 | OUT 1 | output | Constant-current output channel 1, 80 to 400 mA per channel set by R-EXT, with 20 V output driving capability. |
| 8 | N.C. | unconnected | Not connected. |
| 9 | N.C. | unconnected | Not connected. |
| 10 | OUT 2 | output | Constant-current output channel 2, 80 to 400 mA per channel set by R-EXT, with 20 V output driving capability. |
| 11 | OUT 3 | output | Constant-current output channel 3, 80 to 400 mA per channel set by R-EXT, with 20 V output driving capability. |
| 12 | N.C. | unconnected | Not connected. |
| 13 | OE | input | Output enable input, active low; when high all outputs are switched off. |
| 14 | SDO | output | Serial data output terminal; with IOH = -1 mA the output is at least VDD-0.4 V high, and with IOL = 1 mA it is at most 0.4 V low. |
| 15 | R-EXT | passive | Constant-current programming terminal; an external resistor connected here sets the output current of OUT 0 to OUT 3. |
| 16 | VDD | power_in | 5 V supply voltage terminal; recommended range 3.3 V to 5.5 V (5.0 V typical), absolute maximum 0 to 7 V. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
