Product details
Overview
TS3DV642RUATQ1 from Texas Instruments is an automotive-grade, bidirectional 12-channel (6 differential) analog multiplexer/demultiplexer optimized for HDMI 2.0, DisplayPort 1.4 HBR2, MIPI DPHY/CPHY DSI/CSI-2, and LVDS interfaces up to 6 Gbps. It features –3-dB differential bandwidth of 5.8 GHz, insertion loss of –1.6 dB at 3.0 GHz, and operates from a single 3.3 V supply across –40°C to 105°C.
For engineers reviewing the TS3DV642RUATQ1 datasheet, TS3DV642RUATQ1 pinout, TS3DV642RUATQ1 application, or TS3DV642RUATQ1 equivalent, key selection considerations include differential channel count (6), high-speed signal integrity (≤17 ps added jitter at 6 Gbps), automotive AEC-Q200 qualification, IOFF protection at VCC = 0 V, and WQFN-42 wettable flank package compatibility with automated optical inspection.
Technical Context
The TS3DV642RUATQ1 implements a passive FET-based analog switch architecture with integrated charge-pump drive, enabling low on-resistance (6.5–12 Ω) and flatness (<2.0 Ω) across 0–3.6 V common-mode range. Its functional modes are controlled via EN, SEL1, and SEL2 pins to select between Hi-Z, 1:2 demux, 2:1 mux, or full-port A/B routing.
It supports simultaneous differential and single-ended signaling - including HDMI main-link, DDC, HPD, CEC, AUX, and MIPI clock/data lanes - with independent 50 Ω termination handling, inter-pair skew ≤10 ps, and intra-pair skew ≤8 ps. All six differential channels are electrically identical and assignable in arbitrary order per system layout needs.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3DV642RUKTQ1 | Same silicon die, 20-pin WQFN (2.5 mm × 4.5 mm) package - fewer channels (4 differential), lower pin count, no DDC/HPD/CEC support. | Limited to compact 4-lane applications (e.g., single MIPI DSI); unsuitable for full HDMI 2.0 or dual-display DP routing. | Select TS3DV642RUKTQ1 only when board space is constrained and full 6-channel + auxiliary signal support is unnecessary. |
| TMUXHS4212RTVRQ1 | 4-channel, 12-Gbps-capable switch with integrated equalization; higher power (1.2 mA active), no IOFF, different control logic (I²C). | Targets next-gen 8K/16K display links; lacks native HDMI DDC/HPD/CEC pinout and automotive temperature range validation. | Choose TMUXHS4212RTVRQ1 only for future-proof 12 Gbps designs where equalization is required and AEC-Q100 Grade 2 is not mandatory. |
Compared with TS3DV642RUATQ1, TS3DV642RUKTQ1 reduces channel count and auxiliary functionality for space-constrained layouts, while TMUXHS4212RTVRQ1 trades automotive qualification and IOFF for higher data rate and equalization - making TS3DV642RUATQ1 the optimal choice for production-ready 6 Gbps automotive video switching.

FAQ
What is the maximum data rate supported by the TS3DV642RUATQ1?
The TS3DV642RUATQ1 supports differential data rates up to 6 Gbps per lane, validated for HDMI 2.0, DisplayPort 1.4 HBR2, and MIPI DPHY 4.5 Gbps operation. At 6.0 Gbps, it adds only +20 ps total jitter on Port A and +17 ps on Port B versus baseline, staying within industry compliance margins.
Does the TS3DV642RUATQ1 require dual supply voltages?
No, the TS3DV642RUATQ1 operates from a single 3.3 V supply (3.0–3.6 V range) and does not require separate analog/digital rails. Its internal charge-pump generates necessary gate drive voltage, eliminating external bias supplies and simplifying power design.
How does IOFF protection function in the TS3DV642RUATQ1?
IOFF protection in the TS3DV642RUATQ1 disables all switch paths and blocks current flow when VCC = 0 V, preventing back-powering from live I/O signals into a powered-down system. This feature is confirmed in datasheet Section 6.5 (IOFF = ±20 µA at VCC = 0 V).
Can the TS3DV642RUATQ1 be used for both HDMI and MIPI interfaces simultaneously?
Yes - the TS3DV642RUATQ1's 6 differential channels are functionally identical and assignable arbitrarily. One application example routes MIPI DSI clock/data on Channels 0–3 and HDMI DDC/HPD on Channels 4–5, as shown in Figure 9-8 of the official datasheet.
What package type and thermal characteristics does the TS3DV642RUATQ1 have?
The TS3DV642RUATQ1 uses a 42-pin WQFN package (3.5 mm × 9.0 mm, 0.5 mm pitch) with wettable flank and exposed thermal pad. Its thermal metrics include RθJA = 28.7 °C/W and RθJB = 9.7 °C/W, requiring direct thermal pad connection to PCB ground for reliable operation at 105°C ambient.
