Product details
Overview
QS3VH16233PAG8 from Renesas Electronics (formerly IDT) is a 32-bit to 16-bit bidirectional bus switch IC with 2.3V–3.6V VCC operation, 4Ω typical ON resistance, <0.2ns propagation delay, and 5V-tolerant I/Os. It functions as a high-bandwidth MUX/DEMUX for hot-swappable Ethernet LAN switching and rail-to-rail analog signal routing.
For engineers reviewing the QS3VH16233PAG8 datasheet, QS3VH16233PAG8 pinout, QS3VH16233PAG8 application, or QS3VH16233PAG8 equivalent, key selection criteria include its 500 MHz bandwidth, -40°C to +85°C industrial temperature range, TSSOP-56 package, LVTTL-compatible control inputs, and 5V tolerance in both ON and OFF states.
Technical Context
The QS3VH16233PAG8 implements N-channel FET switches without parasitic diodes to VCC, enabling true isolation during power-off and eliminating DC paths to VCC or GND. Its architecture supports dual 16:8 or single 32:16 configuration via independent SELx and TESTx control lines.
Switching is rail-to-rail (0–5V), with flat RON over voltage and temperature, matched channel resistance, and undershoot clamp diodes on all I/O and control pins. Propagation delay is dominated by RC time constant of RON and load capacitance-not internal logic-enabling near-zero added system delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3V to 3.6V - supports both 2.5V and 3.3V logic systems without level translation |
| RON (Typ.) | 4Ω at VCC = 3V - ensures minimal signal attenuation and distortion in high-speed data paths |
| Propagation Delay | <0.2ns - contributes negligible timing budget overhead in 100 Mbps+ Ethernet or memory bus applications |
| I/O Capacitance | 4pF (switch OFF), 8pF (switch ON) - reduces loading on driving sources and improves signal integrity |
| Bandwidth | Up to 500 MHz - enables use in Fast Ethernet (100BASE-TX) and ATM 155 Mbps physical layer switching |
| Temperature Range | -40°C to +85°C - qualified for industrial-grade embedded networking and telecom equipment |
| 5V Tolerance | Yes, on all I/O and control pins in ON/OFF states - allows interfacing with legacy 5V peripherals without external protection |
Pinout & Package
QS3VH16233PAG8 is housed in a 56-pin Thin Shrink Small Outline Package (TSSOP), green RoHS-compliant, with 0.5mm pitch and exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| xA (1A–16A) | Input/Output Bus A | 16 bidirectional data lines connecting to upstream logic (e.g., CPU or MAC controller) |
| xBx (1B1–16B2) | Input/Output Bus B | 32 bidirectional data lines grouped as xB1/xB2 pairs per channel; selected output path(s) |
| SELx (SEL1–SEL2) | Digital Control Input | Selects between xB1 or xB2 for each xA channel; LVTTL-compatible, 2V min VIH at 3.3V VCC |
| TESTx (TEST1–TEST2) | Digital Control Input | Enables single-port (L) or dual-port (H) connection mode; determines whether one or both xB paths are active |
| VCC (pins 37, 48) | Power Supply | Primary logic supply for internal gate drive; must be decoupled locally due to high-frequency switching current |
| GND (pins 1, 47) | Ground Reference | Common return for all I/O and control signals; requires low-inductance connection to minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| No parasitic diode to VCC | Enables safe hot-swap insertion: zero DC path prevents back-powering or latch-up when VCC is off |
| Rail-to-rail analog switching | Supports full 0–5V signal swing without clipping-ideal for low-distortion analog multiplexing in test equipment |
| Undershoot clamp diodes | Protects internal FET gates from negative transients down to -3V, improving robustness in noisy industrial environments |
| High OFF-state impedance | ±1 μA off-state leakage ensures >100 MΩ isolation-critical for preventing crosstalk in dense PCB layouts |
| RON matching across channels | Ensures consistent timing skew and amplitude response across all 32 switched paths-vital for parallel bus integrity |
Applications
| Hot-Swappable Network Card Interface | Fast Ethernet LAN Switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT16233DGGR | Higher RON (6Ω typ.), same TSSOP-56, 4.5V max VI/O, no 5V tolerance | Limited to 3.3V-only systems; unsuitable for mixed-voltage hot-swap where 5V peripherals connect | Choose SN74CBT16233DGGR only if system operates strictly at ≤3.3V and cost is prioritized over 5V tolerance. |
| PI3CH480ELEX | 32:16 configuration, 3.3V-only VCC, 5V-tolerant I/Os, but higher propagation delay (0.35ns) and lower bandwidth (350 MHz) | Acceptable for 100BASE-TX but marginal for 155 Mbps ATM; less suitable for ultra-low-jitter analog paths | Choose PI3CH480ELEX when footprint compatibility is critical and 500 MHz bandwidth is not required. |
Compared with SN74CBT16233DGGR and PI3CH480ELEX, the QS3VH16233PAG8 uniquely combines 5V tolerance, 4Ω RON, and 500 MHz bandwidth-making it the only option qualified for simultaneous hot-swap safety, Fast Ethernet integrity, and low-distortion analog routing in a single device.

FAQ
What is the maximum operating frequency supported by the QS3VH16233PAG8?
The QS3VH16233PAG8 supports up to 500 MHz bandwidth for analog or digital signal switching. Its enable toggle frequency is rated up to 15 MHz under 3.3V conditions, and propagation delay remains below 0.2 ns-ensuring minimal impact on signal timing in Fast Ethernet (100BASE-TX) and ATM 155 Mbps applications. This performance is enabled by its 4Ω typical RON and 4pF I/O capacitance.
Does the QS3VH16233PAG8 support hot-swap functionality?
Yes, the QS3VH16233PAG8 supports hot-swap operation due to its N-channel FET architecture with no parasitic diode to VCC, 5V-tolerant I/Os in both ON and OFF states, and ±1 μA off-state leakage. When VCC is unpowered, the device presents high impedance and zero DC path-preventing back-driving or latch-up during live insertion into systems like modular LAN switches or telecom chassis.
What package type is used for the QS3VH16233PAG8?
The QS3VH16233PAG8 uses a 56-pin Thin Shrink Small Outline Package (TSSOP) with green RoHS-compliant finish and 0.5 mm lead pitch. The package designation "PAG" explicitly indicates this TSSOP variant, which provides compact footprint and thermal performance suitable for high-density networking PCBs while maintaining manufacturability with standard SMT processes.
Can the QS3VH16233PAG8 operate with a 2.5V supply?
Yes, the QS3VH16233PAG8 is fully specified for 2.5V ±0.2V operation, with guaranteed DC and switching parameters including 4Ω typical RON, <0.2 ns propagation delay, and LVTTL-compatible control inputs. Its VCC range of 2.3V to 3.6V makes it interoperable across both 2.5V and 3.3V logic domains without level shifters-common in legacy telecom and industrial control systems.
How does the QS3VH16233PAG8 handle undershoot on its I/O pins?
The QS3VH16233PAG8 integrates undershoot clamp diodes on all switch and control inputs, protecting against negative transients down to -3V (pulse width ≤20 ns). This design feature prevents gate oxide stress and ensures reliable operation in electrically noisy environments such as industrial Ethernet switches or automated test fixtures where cable disconnection can induce ringing or ground bounce.
