LSRV04W-4AT1G from LRC, in a TSOP-6. 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 | I/O1 | passive | ESD-protected channel 1 I/O line, steered by rail diodes, with 1.5pF (max) capacitance to GND and VRWM of 3.3V. |
| 2 | GND | power_in | Negative rail pin connected to system ground; positive ESD current is steered to it through the ESD diode and zener diode. |
| 3 | I/O2 | passive | ESD-protected channel 2 I/O line, steered by rail diodes, with 1.5pF (max) capacitance to GND and VRWM of 3.3V. |
| 4 | I/O4 | passive | ESD-protected channel 4 I/O line, steered by rail diodes, with 1.5pF (max) capacitance to GND and VRWM of 3.3V. |
| 5 | VREF | power_in | Positive rail pin of the diode array, with the integrated zener diode between it and GND clamping positive ESD voltage to the zener voltage. |
| 6 | I/O3 | passive | ESD-protected channel 3 I/O line, steered by rail diodes, with 1.5pF (max) capacitance to GND and VRWM of 3.3V. |
