PT6964 from PTC(Princeton Tech), in a SOP-28-300mil. 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 | OSC | input | Oscillator input; a resistor connected to this pin sets the oscillation frequency, which is 350 to 650 kHz with R=51 kΩ. |
| 2 | DI/O | bidirectional | Serial data input sampled at the rising edge of the shift clock (LSB first) and N-channel open-drain data output; an external pull-up of 1 kΩ to 10 kΩ is recommended. |
| 3 | CLK | input | Shift clock that reads serial data on the rising edge and outputs data on the falling edge, with clock pulse width of at least 400 ns. |
| 4 | STB | input | Serial interface strobe; data input after STB falls is processed as a command, and CLK is ignored while STB is HIGH. |
| 5 | K1 | input | Key data input latched at the end of the display cycle, with an internal pull-low resistor of 40 to 100 kΩ at VDD=5V. |
| 6 | K2 | input | Key data input latched at the end of the display cycle, with an internal pull-low resistor of 40 to 100 kΩ at VDD=5V. |
| 7 | VDD | power_in | Logic supply voltage, 4.5 V minimum, 5 V typical and 5.5 V maximum. |
| 8 | SG1/KS1 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 9 | SG2/KS2 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 10 | SG3/KS3 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 11 | SG4/KS4 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 12 | SG5/KS5 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 13 | SG6/KS6 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 14 | SG7/KS7 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 15 | SG8/KS8 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 16 | SG9/KS9 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 17 | SG10/KS10 | output | Segment output (P-channel open drain) that also acts as key source; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 18 | SG12/GR7 | output | Segment or grid output; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 19 | SG13/GR6 | output | Segment or grid output; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 20 | SG14/GR5 | output | Segment or grid output; high-level output current is -20 to -40 mA at VO=VDD-2V. |
| 21 | VDD | power_in | Logic supply voltage, 4.5 V minimum, 5 V typical and 5.5 V maximum. |
| 22 | GND | power_in | Ground pin, 0 V reference. |
| 23 | GR1 | output | Grid output; low-level output current is 100 to 140 mA at VO=0.3V. |
| 24 | GR2 | output | Grid output; low-level output current is 100 to 140 mA at VO=0.3V. |
| 25 | GND | power_in | Ground pin, 0 V reference. |
| 26 | GR3 | output | Grid output; low-level output current is 100 to 140 mA at VO=0.3V. |
| 27 | GR4 | output | Grid output; low-level output current is 100 to 140 mA at VO=0.3V. |
| 28 | GND | power_in | Ground pin, 0 V reference. |
