SN74AUC2G53DCTR from Texas Instruments, in a MSOP-8. 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 | COM | bidirectional | Common analog switch terminal. Routed to Y1 when INH=L and A=L, or to Y2 when INH=L and A=H. Bidirectional: signals can pass from COM to Y1/Y2 or from Y1/Y2 to COM, at amplitudes up to VCC. |
| 2 | INH | input | Active-high inhibit (enable) control input. When INH=H, both switches are open (no channel selected); when INH=L, the A input selects which channel (Y1 or Y2) is connected to COM. CMOS logic input, 0-3.6 V range. |
| 3 | GND | power_in | Ground reference (0 V). Both GND pins should be tied together to the board ground plane. |
| 4 | GND | power_in | Ground reference (0 V). Second GND pin; tie together with pin 3 to the board ground plane. |
| 5 | A | input | Channel-select control input. With INH=L: A=L selects Y1 to COM, A=H selects Y2 to COM. CMOS logic input, 0-3.6 V range, typical input current 5 µA max. |
| 6 | Y2 | bidirectional | Analog switch terminal for channel 2. Connected to COM when INH=L and A=H. Bidirectional signal path with typical on-resistance ~6 Ω at VCC=2.3 V, ~12.5 Ω at VCC=1.65 V. |
| 7 | Y1 | bidirectional | Analog switch terminal for channel 1. Connected to COM when INH=L and A=L. Bidirectional signal path with typical on-resistance ~6 Ω at VCC=2.3 V, ~12.5 Ω at VCC=1.65 V. |
| 8 | VCC | power_in | Positive supply voltage input. Recommended operating range 0.8 V to 2.7 V; typical supply current ICC = 10 µA max at VCC=2.7 V. Decouple to GND with a 0.1 µF ceramic capacitor. |
