SN74CBTLV3253PWR from Texas Instruments, in a TSSOP-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 | 1OE | input | Output Enable 1, active-low; when high, channel 1 multiplexer is disabled. |
| 2 | S1 | input | Select input 1; with S0 controls which B port (B1-B4) connects to A port when OE is low. |
| 3 | 1B4 | bidirectional | Channel 1 I/O port 4; bidirectional switch port selectable via S0, S1 inputs. |
| 4 | 1B3 | bidirectional | Channel 1 I/O port 3; bidirectional switch port selectable via S0, S1 inputs. |
| 5 | 1B2 | bidirectional | Channel 1 I/O port 2; bidirectional switch port selectable via S0, S1 inputs. |
| 6 | 1B1 | bidirectional | Channel 1 I/O port 1; bidirectional switch port selectable via S0, S1 inputs. |
| 7 | 1A | bidirectional | Channel 1 common port; bidirectional switch connecting to selected 1Bx based on S1, S0 when 1OE is low. |
| 8 | GND | power_in | Ground reference; 0V power supply return. |
| 9 | 2A | bidirectional | Channel 2 common port; bidirectional switch connecting to selected 2Bx based on S1, S0 when 2OE is low. |
| 10 | 2B1 | bidirectional | Channel 2 I/O port 1; bidirectional switch port selectable via S0, S1 inputs. |
| 11 | 2B2 | bidirectional | Channel 2 I/O port 2; bidirectional switch port selectable via S0, S1 inputs. |
| 12 | 2B3 | bidirectional | Channel 2 I/O port 3; bidirectional switch port selectable via S0, S1 inputs. |
| 13 | 2B4 | bidirectional | Channel 2 I/O port 4; bidirectional switch port selectable via S0, S1 inputs. |
| 14 | S0 | input | Select input 0; with S1 controls which B port (B1-B4) connects to A port when OE is low. |
| 15 | 2OE | input | Output Enable 2, active-low; when high, channel 2 multiplexer is disabled. |
| 16 | VCC | power_in | Positive power supply; 2.3V to 3.6V recommended operating range per Section 5.3. |
