TC7USB42MU

TOSHIBA SEMICONDUCTOR AND STORAGE · Global Sourcing Parts · UQFN-10(1.4x1.8)

TC7USB42MU from TOSHIBA SEMICONDUCTOR AND STORAGE, in a UQFN-10(1.4x1.8). 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 D+ bidirectional Common D+ switch terminal, connected to 1D+ or 2D+ according to S when OE is low; switch I/O voltage 0 to 4.3 V.
2 D- bidirectional Common D- switch terminal, connected to 1D- or 2D- according to S when OE is low; switch I/O voltage 0 to 4.3 V.
3 GND power_in Ground pin.
4 1D- bidirectional Switch terminal 1D-, connected to D- when OE is low and S is low; high impedance otherwise.
5 1D+ bidirectional Switch terminal 1D+, connected to D+ when OE is low and S is low; high impedance otherwise.
6 2D- bidirectional Switch terminal 2D-, connected to D- when OE is low and S is high; high impedance otherwise.
7 2D+ bidirectional Switch terminal 2D+, connected to D+ when OE is low and S is high; high impedance otherwise.
8 OE input Active-low output enable input; when high the switches are open and high impedance exists regardless of S, input range 0 to 4.3 V.
9 VCC power_in Supply voltage pin, operating range 2.3 to 4.3 V.
10 S input Select input; low connects D+/D- to 1D+/1D-, high connects to 2D+/2D- when OE is low; input range 0 to 4.3 V.
