**Texas Instruments** · Analog Switches, Multiplexers · VSSOP-8-0.5mm

SN74LVC2G53DCUR from Texas Instruments, in a VSSOP-8-0.5mm. 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 | COM | bidirectional | Bidirectional switch common terminal; handles analog and digital signals up to 5.5V peak amplitude in both directions. |
| 2 | INH | input | Active-high inhibit control input; switches disabled when high, enabled when low. |
| 3 | GND | power_in | Ground pin |
| 4 | GND | power_in | Ground pin |
| 5 | A | input | Address select control input; low selects Y1 channel, high selects Y2 channel. |
| 6 | Y2 | bidirectional | Bidirectional switch signal terminal for Y2 channel selected when A input is high; handles signals up to 5.5V peak amplitude. |
| 7 | Y1 | bidirectional | Bidirectional switch signal terminal for Y1 channel selected when A input is low; handles signals up to 5.5V peak amplitude. |
| 8 | VCC | power_in | Positive power supply pin rated from 1.65V to 5.5V with maximum continuous current of ±100mA. |
