Product details
Overview
QS3VH16233PAG from Renesas Electronics (formerly IDT) is a 32-bit to 16-bit high-bandwidth analog bus switch with N-channel FET architecture, 4 Ω typical ON resistance, <0.2 ns propagation delay, and 5 V-tolerant I/Os operating at 2.3–3.6 V supply. It functions as dual 16:8 or single 32:16 multiplexer/demultiplexer in hot-swap and Ethernet LAN switching applications.
For engineers reviewing the QS3VH16233PAG datasheet, QS3VH16233PAG pinout, QS3VH16233PAG application, or QS3VH16233PAG equivalent, key selection criteria include rail-to-rail 0–5 V switching capability, 500 MHz bandwidth, industrial temperature range (–40°C to +85°C), LVTTL-compatible control inputs, and TSSOP-56 package compatibility.
Technical Context
The QS3VH16233PAG implements a dual-path 16-channel bus switch array controlled by two independent SELx/TESTx logic pairs, enabling configurable 16:8 or 32:16 data routing. Its N-channel FET topology eliminates parasitic diodes to VCC, ensuring isolation during power-off and no DC path to supply or ground.
Each switch channel supports bidirectional rail-to-rail operation (0–5 V), maintains flat RON across voltage and temperature, and delivers <4 pF I/O capacitance with 5 V tolerance in both ON and OFF states-critical for signal integrity in high-speed communications and hot-plug interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - supports 2.5 V and 3.3 V logic systems without level translation |
| RON (Typ.) | 4 Ω at VCC = 3 V - enables low-insertion-loss analog/digital signal routing |
| Propagation Delay | <0.2 ns - contributes negligible timing skew in high-speed bus architectures |
| Bandwidth | Up to 500 MHz - suitable for Fast Ethernet (100BASE-TX) and ATM 155 Mbps switching |
| I/O Capacitance | 4 pF typical - minimizes loading on driving sources and preserves edge rates |
| Temperature Range | –40°C to +85°C - qualified for industrial-grade embedded and networking equipment |
| ESD Protection | Undershoot clamp diodes on all switch and control inputs - protects against transient coupling during hot-swap events |
Pinout & Package
QS3VH16233PAG is housed in a 56-pin Thin Shrink Small Outline Package (TSSOP), lead-free and RoHS-compliant ("Green" designation per ordering code PAG). The package measures 12.5 mm × 6.1 mm × 1.2 mm with 0.5 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| xA (x = 1–16) | Input/Output Bus A | Primary 32-bit bidirectional data port (A1–A16, each with two pins) |
| xB1, xB2 (x = 1–16) | Input/Output Bus B | Secondary 16×2 = 32-bit demux/mux output ports (B1–B16, each with two pins) |
| SEL1, SEL2 | Digital Control Input | Selects between xB1 or xB2 path per channel group under TESTx enable |
| TEST1, TEST2 | Digital Control Input | Enables one or both xB paths per 16-bit group; determines 16:8 vs. 32:16 mode |
| VCC, GND | Power Supply | Dual VCC and multiple GND pins ensure low-noise, low-impedance supply distribution |
Key Features
| Feature | Design Value |
|---|---|
| No parasitic diode to VCC | Enables true power-off isolation - prevents backfeeding and latch-up in live-backplane systems |
| 5 V-tolerant I/Os | Allows interfacing with legacy 5 V buses while powered from 2.5/3.3 V rails - eliminates external level shifters |
| Rail-to-rail 0–5 V switching | Preserves full analog/digital signal swing across mixed-voltage domains without clipping or distortion |
| Low 4 pF I/O capacitance | Reduces capacitive loading on source drivers - maintains signal rise/fall times & system bandwidth |
| Flat RON vs. voltage/temp | Ensures consistent channel matching and minimal crosstalk in multi-channel parallel data paths |
Applications
| Hot-Swappable I/O Card Interface | Fast Ethernet LAN Switching |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-bandwidth bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT16233DGGR | Higher RON (6 Ω typ.), wider VCC range (4.5–5.5 V), no 5 V-tolerant OFF-state | Requires 5 V supply; unsuitable for mixed-voltage hot-swap where VCC = 3.3 V but data lines reach 5 V | Select when system uses only 5 V logic and does not require power-off isolation or 5 V tolerance at 3.3 V bias |
| PI3CH480ELEX | Single 24-bit 12:12 switch; lower bandwidth (300 MHz), no TESTx port-select logic | Lacks dual-group configuration flexibility; cannot emulate 32:16 mode or independent 16:8 operation | Select for simpler 24-bit mux/demux needs where pin count and control logic overhead must be minimized |
Compared with SN74CBT16233DGGR and PI3CH480ELEX, the QS3VH16233PAG uniquely supports 32:16 reconfigurable routing, 5 V tolerance at 3.3 V VCC, and true power-off isolation - making it the only option for industrial hot-swap and mixed-voltage Ethernet switch designs requiring zero down time.

FAQ
What is the maximum operating frequency supported by the QS3VH16233PAG?
The QS3VH16233PAG supports an operating frequency of up to 500 MHz, verified by its bandwidth specification and confirmed in the datasheet's "High Bandwidth" feature listing. This enables use in Fast Ethernet (100BASE-TX) and ATM 155 Mbps applications. The 500 MHz rating reflects small-signal AC performance under defined load conditions, not guaranteed for arbitrary digital clock frequencies.
Does the QS3VH16233PAG support hot-swap functionality, and how is it implemented?
Yes, the QS3VH16233PAG supports hot-swap functionality through three key features: 5 V-tolerant I/Os in both ON and OFF states, N-channel FETs with no parasitic diode to VCC, and undershoot clamp diodes on all inputs. These allow safe insertion into live backplanes without backfeeding or latch-up. The QS3VH16233PAG achieves true power-off isolation - critical for IEEE 1101.10-compliant systems.
What is the ON resistance (RON) of the QS3VH16233PAG, and how does it vary with supply voltage?
The QS3VH16233PAG has a typical ON resistance of 4 Ω at VCC = 3.0 V and 6 Ω at VCC = 2.5 V, as specified in the DC Electrical Characteristics table. Its RON remains flat across input voltage (0–5 V) and temperature (–40°C to +85°C), ensuring consistent channel matching. This behavior is confirmed by the "Flat RON characteristics over operating range" feature and the Typical RON vs. VIN graph.
Can the QS3VH16233PAG be used in analog signal paths, and what specifications support that use case?
Yes, the QS3VH16233PAG is qualified for analog signal routing due to rail-to-rail 0–5 V switching, low 4 pF I/O capacitance, 4 Ω typical RON, and excellent RON matching between channels. Its low distortion and high OFF impedance (>1 GΩ) make it suitable for low-noise analog multiplexing - explicitly cited in the Applications section as "Low distortion analog switch" and validated by THD and crosstalk performance in reference designs.
What package type and pin count does the QS3VH16233PAG use, and is it RoHS-compliant?
The QS3VH16233PAG uses a 56-pin Thin Shrink Small Outline Package (TSSOP) with 0.5 mm pitch, designated "PAG" in the ordering code. It is lead-free and RoHS-compliant, as confirmed by the "Green" package notation in the Ordering Information section and Renesas' corporate compliance documentation. The package dimensions are 12.5 mm × 6.1 mm × 1.2 mm.
