Overview
The TMUXHS221NKGT is a high-speed bidirectional 2:1/1:2 multiplexer/demultiplexer switch optimized for USB 2.0 and eUSB2 signaling. It operates with a supply voltage of 3.3 V (range 3.0 to 3.6 V) and supports data signals within a -0.3 to 3.6 V range. The device features a low channel ON resistance of 3 Ω at VI/O = 0 V, a -3 dB bandwidth of 3.3 GHz, and a propagation delay of 80 ps. It provides an off-isolation of -32 dB at 240 MHz and operates across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Compatible with USB 2.0 and eUSB2 LS, FS, and HS physical layers
- Supports differential or single-ended CMOS signals up to 3 Gbps
- Data pins are 5 V tolerant
- Extended industrial temperature range from -40°C to 125°C
Applications
- PC and notebooks
- Gaming, TV, home theater, and entertainment
- Data center and enterprise computing
- Medical applications
- Test and measurements
Procurement Notes
Verify the specific ordering suffix NKGT corresponds to the UQFN-10 package with small tape-and-reel carrier quantities. Confirm RoHS compliance and lead finish specifications against the manufacturer's latest orderable addendum. Ensure design compatibility with the required 3.3 V supply voltage and control logic levels before finalizing procurement.
Selection Notes
Select this component when routing high-speed differential signals such as USB 2.0 or eUSB2 in space-constrained designs. The UQFN-10 package offers a compact footprint suitable for mobile phones, tablets, and portable devices. Verify that the application requires passive switching without signal regeneration and can accommodate the specified ON resistance and bandwidth characteristics.
Part Context
The TMUXHS221NKGT belongs to the Texas Instruments TMUXHS221 family of analog switches. This series is designed specifically for high-frequency signal integrity in consumer electronics and industrial systems. The NKG suffix identifies the specific 10-pin UQFN package variant used in this part number.
Replacement Considerations
The datasheet indicates pin-to-pin and BoM-to-BoM compatibility with multiple sources. Verify functional equivalence regarding ON resistance, bandwidth, and thermal performance before substituting.
