TMUXHS4212IRKSR

Overview

The TMUXHS4212 is a high-speed bidirectional passive switch configured as a 2-channel 2:1 multiplexer or 1:2 demultiplexer. It supports differential signaling with data rates up to 16 Gbps, accommodating interfaces such as USB 3.2 Gen 2.0 and PCIe Gen 4.0. The device features a −3-dB differential bandwidth of 13 GHz and operates on a single supply voltage (VCC) of either 1.8 V or 3.3 V. Active power consumption is 180 μA, while standby current drops below 2 μA. It accommodates common mode voltages from 0 to 1.8 V through adaptive tracking. The component is housed in a 20-pin VQFN package measuring 2.5 mm × 4.5 mm.

Feature Summary

Adaptive common mode voltage tracking maintains signal integrity across varying input levels.
Ultra-low power consumption with distinct active and standby operational modes.
Optimized silicon design ensures minimal intra-pair skew for high-frequency signals.

Applications

USB Type-C port switching for plug flip accommodation
PCI Express lane muxing between motherboard slots
High-speed interface routing in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and temperature range. Ensure the selected variant matches the required operating conditions for the target application environment.

Selection Notes

Select this component for applications requiring bidirectional switching of high-speed differential pairs. Confirm that the system's common mode voltage remains within the supported 0 to 1.8 V range and that the board layout accommodates the specified package dimensions.

Part Context

This device belongs to the TMUXHS4212 family of high-speed analog switches. It is designed specifically for generic differential signaling applications where low insertion loss and high isolation are critical for maintaining signal quality at multi-gigabit data rates.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same product family. Verify that any substitute part maintains identical electrical characteristics and package dimensions for seamless integration.

FAQ

How does the device handle different common mode voltages?

The TMUXHS4212 utilizes adaptive common mode voltage tracking to ensure the channel remains unchanged across the entire supported common mode voltage range of 0 to 1.8 V.
