Product details
Overview
TS3L110RGYR from Texas Instruments is a quad SPDT high-bandwidth LAN switch configured as a 4-bit 1-of-2 multiplexer/demultiplexer with single enable (E) and select (S) control. It delivers 500 MHz typical bandwidth, –30 dB typical crosstalk, 4 Ω typical ON-state resistance, and operates from 3 V to 3.6 V. It routes 10/100 Base-T Ethernet signals between RJ-45 ports and PHY in laptops and docking stations.
For engineers reviewing the TS3L110RGYR datasheet, TS3L110RGYR pinout, TS3L110RGYR application, or TS3L110RGYR equivalent, this page provides verified technical context, real-world signal routing constraints, Ioff partial-power-down behavior, and validated alternatives for LAN switching designs requiring low skew and high isolation.
Technical Context
The TS3L110RGYR implements a bidirectional analog switch architecture with CMOS control logic, supporting differential 8-channel-to-4-channel multiplexing via four independent SPDT paths. Each path features matched ron(flat) ≤1 Ω and channel-to-channel skew <0.2 ns under 3.3 V operation.
Its Ioff functionality guarantees high-impedance isolation when VCC = 0 V, preventing backflow current during partial power-down. The device uses undershoot clamp diodes on all data and control inputs and meets JESD 78 Class II latch-up immunity (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 500 MHz typical - supports full 100 Base-T signaling without attenuation beyond –3 dB point. |
| ON-state resistance | 4 Ω typical - ensures minimal insertion loss and voltage drop across active signal paths. |
| ron flatness | 1 Ω max - maintains consistent impedance across input voltage range (1.25 V to VCC), critical for signal integrity in differential LAN pairs. |
| Crosstalk | –30 dB typical at 250 MHz - suppresses interference between adjacent switched channels in multi-port Ethernet routing. |
| Supply voltage | 3 V to 3.6 V - compatible with standard 3.3 V system rails and decoupled via 0.1–10 µF capacitor at VCC. |
| Enable propagation delay | 0.5–7 ns - enables fast switching between RJ-45 ports with deterministic timing control. |
| Ioff leakage | 1 µA max at VCC = 0 - ensures safe isolation during system sleep or hot-swap events without damaging current flow. |
Pinout & Package
VQFN-16 (RGY) package, 4.00 mm × 4.00 mm body, 0.5 mm pitch, exposed thermal pad tied to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Select input | Controls path selection per channel: S = L connects IAx/YA, IBx/YB, ICx/YC, IDx/YD to first port; S = H selects second port. |
| 2–3, 5–6, 10–11, 13–14 (IA0–IA1, IB0–IB1, IC0–IC1, ID0–ID1) | Data I/Os (I-side) | Four bidirectional differential I/O pairs - connect to RJ-45 connector pins; support 0–5 V signal swing. |
| 4, 7, 9, 12 (YA, YB, YC, YD) | Data I/Os (Y-side) | Four bidirectional differential I/Os - route to Ethernet PHY transceiver; match impedance to 100 Ω differential lines. |
| 8 (GND) | Ground reference | Primary 0 V reference; thermal pad must be soldered to PCB ground plane for thermal and EMI performance. |
| 15 (E) | Enable input | Active-low enable: E = L activates all switches; E = H places all I–Y paths in high-Z state for isolation. |
| 16 (VCC) | Positive supply | 3.0–3.6 V power rail; requires local 0.1–10 µF decoupling capacitor placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide analog bandwidth | 500 MHz typical - preserves signal fidelity for 100 Base-T (125 MHz symbol rate) with margin. |
| Low and flat ON-resistance | ron = 4 Ω typical, ron(flat) = 1 Ω - minimizes amplitude distortion and timing skew across voltage range. |
| Partial power-down support | Ioff ≤1 µA at VCC = 0 - enables safe integration into systems with staggered power sequencing or hot-swap capability. |
| High channel isolation | –30 dB crosstalk, –28 dB OFF isolation - prevents coupling between active and inactive Ethernet lanes. |
| Robust ESD protection | ±2000 V HBM, ±1000 V CDM - withstands handling and board-level ESD events without degradation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LAN switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3L301RGYR | Single-pole double-throw (SPDT), 1-channel; same VQFN-16 package and 3.3 V supply, but only one switch path vs. quad. | Suitable for single-lane routing (e.g., MDI/MDI-X selection), not multi-port LAN aggregation. | Choose TS3L301RGYR only when routing a single differential pair and space/power constraints favor lower channel count. |
| SN74CBT3245APW | Octal FET bus switch, TSSOP-24; 5 V tolerant, higher ron (~7 Ω), no Ioff, no guaranteed 100 Base-T bandwidth spec. | Designed for general-purpose digital bus switching, not optimized for differential LAN signal integrity or crosstalk. | Use SN74CBT3245APW only in non-critical 10 Base-T or low-frequency analog routing where isolation and bandwidth are secondary. |
Compared with TS3L301RGYR and SN74CBT3245APW, the TS3L110RGYR uniquely combines quad SPDT topology, 500 MHz bandwidth, Ioff-enabled partial power-down, and –30 dB crosstalk-making it the only option qualified for reliable 100 Base-T multi-port switching in space-constrained VQFN layouts.

FAQ
What is the maximum operating frequency supported by the TS3L110RGYR?
The TS3L110RGYR has a typical bandwidth of 500 MHz, verified per Figure 6 in the official datasheet. This supports full 100 Base-T Ethernet (125 MHz symbol rate) with significant margin, ensuring signal integrity through the –3 dB point at 627 MHz in typical conditions. The TS3L110RGYR is not rated for Gigabit Ethernet frequencies.
Does the TS3L110RGYR support partial power-down mode?
Yes, the TS3L110RGYR supports partial power-down via its Ioff feature. When VCC = 0 V, Ioff leakage is limited to 1 µA maximum, preventing damaging backflow current from live I/O lines into the unpowered device. This behavior is explicitly characterized in Section 6.5 of the TS3L110RGYR datasheet.
What is the pin-compatible replacement for TS3L110RGYR in VQFN-16?
No pin-compatible replacement exists for TS3L110RGYR in the VQFN-16 (RGY) package. Alternative packages (e.g., SOIC-D, SSOP-DBQ) share identical pinout and function, but no other manufacturer offers an exact pin-for-pin, function-for-function VQFN-16 quad SPDT LAN switch with matching 500 MHz bandwidth and Ioff specification.
How does the TS3L110RGYR handle differential Ethernet signals?
The TS3L110RGYR routes differential 10/100 Base-T signals as matched pairs (e.g., IA0/IA1 ↔ YA, IB0/IB1 ↔ YB). Its low ron flatness (≤1 Ω) and <0.2 ns channel skew preserve differential timing and amplitude balance. Layout guidelines in Section 11 mandate continuous ground planes and stub-free traces to maintain 100 Ω differential impedance.
What is the recommended decoupling for TS3L110RGYR VCC?
Texas Instruments specifies a 0.1 µF to 10 µF ceramic decoupling capacitor placed as close as possible to the TS3L110RGYR VCC pin (Pin 16), referenced directly to Pin 8 (GND). This mitigates high-frequency noise and ensures stable switching performance across the 500 MHz bandwidth, per Section 10 and Figure 12 of the datasheet.
