LSF0204QPWRQ1 from Texas Instruments, in a TSSOP-14. 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 | VREF_A | power_in | Reference supply voltage for the A-side. Sets the lower of the two translation voltages (0.8 V to 4.5 V). Must be less than or equal to VREF_B. |
| 2 | A1 | bidirectional | Bidirectional input/output 1 on the A-side (lower-voltage domain). Pulled up to VREF_A externally; signal translates to B1. |
| 3 | A2 | bidirectional | Bidirectional input/output 2 on the A-side (lower-voltage domain). Pulled up to VREF_A externally; signal translates to B2. |
| 4 | A3 | bidirectional | Bidirectional input/output 3 on the A-side (lower-voltage domain). Pulled up to VREF_A externally; signal translates to B3. |
| 5 | A4 | bidirectional | Bidirectional input/output 4 on the A-side (lower-voltage domain). Pulled up to VREF_A externally; signal translates to B4. |
| 6 | NC | unconnected | No connection. Not internally connected. May be left floating or tied to ground. |
| 7 | GND | power_in | Ground reference for the device (0 V). |
| 8 | EN | input | Translation enable input, active-high. Drive high (>=0.7×VREF_A or >=0.8×VREF_A depending on Vref_A range) to enable translation. Drive low to place I/Os in a high-impedance state. EN is powered from VREF_A and must be low during power-up/down to guarantee high-Z. |
| 9 | NC | unconnected | No connection. Not internally connected. May be left floating or tied to ground. |
| 10 | B4 | bidirectional | Bidirectional input/output 4 on the B-side (higher-voltage domain). Pulled up to VREF_B externally; signal translates to A4. |
| 11 | B3 | bidirectional | Bidirectional input/output 3 on the B-side (higher-voltage domain). Pulled up to VREF_B externally; signal translates to A3. |
| 12 | B2 | bidirectional | Bidirectional input/output 2 on the B-side (higher-voltage domain). Pulled up to VREF_B externally; signal translates to A2. |
| 13 | B1 | bidirectional | Bidirectional input/output 1 on the B-side (higher-voltage domain). Pulled up to VREF_B externally; signal translates to A1. |
| 14 | VREF_B | power_in | Reference supply voltage for the B-side. Sets the higher of the two translation voltages (1.8 V to 5.5 V). Must be greater than or equal to VREF_A. |
