Product details
Overview
QS3VH16210 from Renesas Electronics (formerly IDT) is a 2.5V/3.3V, 20-bit, dual 10-bit 2-port bus switch with N-channel FET architecture, 4Ω typical ON resistance, <0.2 ns propagation delay, and 5V-tolerant I/Os. It enables rail-to-rail bidirectional signal routing in hot-swap-capable Ethernet LAN switches and high-speed communications backplanes.
For engineers reviewing the QS3VH16210 datasheet, QS3VH16210 pinout, QS3VH16210 application, or QS3VH16210 equivalent, key selection criteria include its industrial temperature range (–40°C to +85°C), TSSOP-48 package, LVTTL-compatible active-low enable controls, 500 MHz bandwidth, and isolation under power-off conditions.
Technical Context
The QS3VH16210 implements two independent 10-bit bus switches, each controlled by dedicated active-low xOE inputs (1OE and 2OE), supporting simultaneous or isolated switching of A↔B ports. Its N-channel FET design eliminates parasitic diodes to VCC, enabling true 5V tolerance in both ON and OFF states and zero DC path to VCC or GND.
Signal integrity is maintained via low 4 pF typical I/O capacitance (OFF state), flat RON over voltage and temperature, and near-zero ground bounce due to bidirectional, flow-through topology. Propagation delay remains under 0.2 ns because delay is dominated solely by RC time constant of RON and load capacitance-not internal logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V to 3.6V - supports mixed 2.5V/3.3V system interfacing without level shifters |
| RON (Typ.) | 4Ω at VCC = 3V - ensures minimal insertion loss and signal distortion for high-fidelity analog/digital switching |
| Propagation Delay | <0.2 ns - preserves timing integrity in >100 Mbps Ethernet and ATM 25/155 systems |
| I/O Capacitance (OFF) | 4 pF typical - reduces loading on driving sources and improves high-frequency signal fidelity |
| Bandwidth | Up to 500 MHz - enables use in fast serial data paths and wide parallel buses without attenuation |
| Temperature Range | –40°C to +85°C - qualified for industrial-grade embedded networking and telecom equipment |
| 5V Tolerance | Yes on all I/Os in ON/OFF states - allows safe interfacing with legacy 5V logic or analog signals |
Pinout & Package
QS3VH16210 is packaged in a 48-pin Thin Shrink Small Outline Package (TSSOP), lead-free and RoHS-compliant (Green). The package measures 12.5 mm × 6.1 mm × 1.2 mm with 0.5 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE | Active-low enable controls | Independent gating of Port 1 and Port 2; LOW connects A↔B, HIGH isolates |
| 1A1–1A10, 2A1–2A10 | Port A inputs/outputs | First and second 10-bit data channels on side A; bidirectional, 5V-tolerant |
| 1B1–1B10, 2B1–2B10 | Port B inputs/outputs | Corresponding 10-bit channels on side B; fully matched RON and timing to A-side |
| VCC | Power supply | 2.3V–3.6V digital supply; powers control logic and switch bias circuitry |
| GND | Ground reference | Common return for all I/Os and internal circuitry; multiple pins reduce ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| No parasitic diode to VCC | Enables safe power-off isolation and prevents back-driving or latch-up when VCC = 0V |
| Rail-to-rail switching (0–5V) | Supports full-swing analog signals and mixed-voltage digital interfaces without clipping |
| RON matching between channels | Ensures uniform timing skew across all 20 bits-critical for parallel bus integrity |
| Undershoot clamp diodes | Protects all switch and control inputs against –3V transient undershoot per AC rating |
| LVTTL-compatible control inputs | Accepts standard 3.3V/2.5V logic thresholds without external biasing or translation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-bandwidth bus switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT16210DGGR | Same 20-bit dual-port architecture, 5V-tolerant, but RON = 6Ω typical and tPD = 0.25 ns max; operates at 4.5V–5.5V only | Requires 5V supply; not suitable for 2.5V/3.3V-only systems or industrial temp range beyond +70°C | Select when legacy 5V infrastructure dominates and higher RON is acceptable |
| PI3CH210ZHE | 20-bit bus switch with 3.3V-only operation, RON = 5Ω typical, tPD = 0.2 ns, but lacks undershoot clamps and 5V tolerance in OFF state | Not rated for hot-swap or mixed-voltage interfaces where 5V signals may appear during fault conditions | Select for cost-sensitive 3.3V-only designs where robustness to overvoltage is not required |
Compared with SN74CBT16210DGGR and PI3CH210ZHE, the QS3VH16210 uniquely combines 2.5V/3.3V operation, guaranteed –40°C to +85°C performance, 5V tolerance in both states, and undershoot protection-making it the only choice for ruggedized hot-swap and telecom infrastructure applications.

FAQ
What is the operating voltage range for QS3VH16210?
The QS3VH16210 operates from 2.3V to 3.6V on VCC, supporting both 2.5V and 3.3V logic systems. Its I/Os are 5V-tolerant in both ON and OFF states, allowing safe interfacing with higher-voltage signals without external protection. This dual-voltage capability makes QS3VH16210 ideal for bridging legacy and modern subsystems within a single board design.
Does QS3VH16210 support hot-swap functionality?
Yes, QS3VH16210 is explicitly designed for hot-swap applications. Its N-channel FET architecture eliminates parasitic diodes to VCC, ensuring no DC path to supply or ground during power-off conditions. Combined with 5V-tolerant I/Os and undershoot clamp diodes, QS3VH16210 safely isolates live backplanes during card insertion-enabling zero-downtime system maintenance as confirmed in its functional block diagram and application notes.
What is the maximum signal bandwidth supported by QS3VH16210?
The QS3VH16210 supports up to 500 MHz bandwidth, verified by its low 4Ω typical ON resistance and 4 pF OFF-state I/O capacitance. This bandwidth enables clean transmission of fast edges in 100 Mbps Ethernet, ATM 155 Mbps, and other high-speed digital protocols. The device's flat RON vs. VIN curve and rail-to-rail switching further ensure minimal amplitude distortion across the full frequency range.
How many independent switch banks does QS3VH16210 contain?
The QS3VH16210 contains two independent 10-bit switch banks (Port 1 and Port 2), each with dedicated active-low enable inputs (1OE and 2OE). This dual-port architecture allows selective routing or isolation of separate data paths-for example, one port for address lines and another for data lines-without crosstalk or shared control timing constraints in the QS3VH16210 implementation.
Is QS3VH16210 compatible with LVTTL logic levels?
Yes, QS3VH16210 control inputs are LVTTL-compatible: VIH is guaranteed ≥2.0V and VIL ≤0.8V over the full VCC range (2.3V–3.6V). This ensures reliable recognition of standard 3.3V and 2.5V logic outputs without level-shifting circuitry. The QS3VH16210 datasheet explicitly lists "LVTTL-compatible control inputs" as a core feature, validated across industrial temperature and voltage corners.
