TC7USB40FT

TOSHIBA · Analog Switches, Multiplexers · TSSOP-14

TC7USB40FT from TOSHIBA, in a TSSOP-14. 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 NC unconnected No connection pin.
2 S input Common select input choosing the 1D or 2D port pair (L = 1D+/1D-, H = 2D+/2D-); input range 0 to 4.3 V, unused inputs must be tied to VCC or GND.
3 1D+ bidirectional Switch terminal 1D+, connected to D+ when OE = L and S = L; switch I/O voltage 0 to 4.3 V.
4 2D+ bidirectional Switch terminal 2D+, connected to D+ when OE = L and S = H; switch I/O voltage 0 to 4.3 V.
5 D+ bidirectional Common D+ switch terminal, connected to 1D+ or 2D+ per S and open (high-impedance) when OE is high.
6 GND power_in Ground pin.
7 NC unconnected No connection pin.
8 NC unconnected No connection pin.
9 D- bidirectional Common D- switch terminal, connected to 1D- or 2D- per S and open (high-impedance) when OE is high.
10 2D- bidirectional Switch terminal 2D-, connected to D- when OE = L and S = H; switch I/O voltage 0 to 4.3 V.
11 1D- bidirectional Switch terminal 1D-, connected to D- when OE = L and S = L; switch I/O voltage 0 to 4.3 V.
12 OE input Active-low output enable input; when high both switches are open regardless of S, input range 0 to 4.3 V.
13 VCC power_in Supply voltage, 2.3 to 4.3 V operating range (absolute maximum -0.5 to 4.6 V).
14 NC unconnected No connection pin.
