TC7USB40FT(EL)

Analog Switches - Special Purpose Overview

The TC7USB40FT is a high-speed CMOS dual single-pole double-throw (SPDT) USB switch manufactured by Toshiba. It functions as a dual 1-to-2 multiplexer/demultiplexer with common select and output enable inputs, designed for USB 2.0 applications supporting data rates up to 480 Mbps. The device operates within a supply voltage range of 2.3 V to 4.3 V and features low ON-resistance of 4.5 Ω typical at 3 V, alongside a switch terminal ON-capacitance of 5 pF. It provides -3 dB bandwidth of 1.5 GHz and includes power-down protection on all I/O ports. The component is housed in a TSSOP14 package.

Consult Toshiba's official cross-reference documentation or contact technical support for verified equivalent part numbers. Do not substitute with generic multiplexers without verifying ON-resistance and capacitance parameters.

Analog Switches - Special Purpose FAQ

What is the maximum data rate supported by this switch?

The TC7USB40FT supports USB 2.0 applications with a data rate of up to 480 Mbps.

How does the Output Enable (OE) pin affect operation?

When OE is held high, the switches open regardless of the Select input state, placing the outputs in a high-impedance disconnected state.

What is the typical ON-resistance flatness?

The typical ON-resistance flatness is 1.3 Ω when measured at a supply voltage of 3 V.
