TC7USB3212WBG(ELAH

Overview

The TC7USB3212WBG is a CMOS digital integrated circuit functioning as a quad single-pole double-throw (SPDT) multiplexer/demultiplexer designed for USB 3.0 and high-speed interface applications. It operates on a single power supply ranging from 1.65 V to 1.95 V. The device features four independent channels with common select (SEL) and output enable (OE) inputs. Key electrical specifications include a typical ON-resistance of 4.5 Ω at 1.65 V, a -3 dB bandwidth of 8 GHz, and an insertion loss of -1 dB at 2.5 GHz. It supports an operating temperature range of -40°C to 85°C and utilizes a WCSP20 package.

Feature Summary

• Quad SPDT architecture providing four independent differential signal paths for USB 3.0 data routing
• Low ON-resistance and high bandwidth characteristics optimized for high-speed signal integrity
• Integrated power-down protection on all inputs and outputs to prevent leakage during shutdown
• Built-in electrostatic discharge (ESD) protection circuits on all input pins

Applications

• USB 3.0 (5 Gbps) interface switching
• High-speed differential signal multiplexing
• Portable electronic devices requiring low-voltage operation

Procurement Notes

Verify the specific ordering suffix and packaging configuration against current manufacturer documentation before procurement.

FAQ

How does the Output Enable (OE) pin affect the switch state?

When the OE input is held high, the switches are turned off, creating a high-impedance state between the ports regardless of the Select (SEL) input state.

What is the function of the Select (SEL) input?

The SEL input determines which output port (B or C) is connected to the common input port (A) when the Output Enable (OE) is active low.

Does the device support power-down protection?

Yes, the TC7USB3212WBG provides power-down protection on all inputs and outputs to ensure safe operation during power-off states.
