Product details
Overview
QS3VH253PAG from Renesas Electronics (formerly IDT) is a dual 4:1 analog multiplexer/demultiplexer bus switch with N-channel FET architecture, 4 Ω typical ON resistance, <0.2 ns propagation delay, and 5 V tolerance in both ON/OFF states. It operates from 2.3 V to 3.6 V supply and supports rail-to-rail 0–5 V signal switching for hot-swap and high-bandwidth communication interfaces.
For engineers reviewing the QS3VH253PAG datasheet, QS3VH253PAG pinout, QS3VH253PAG application, or QS3VH253PAG equivalent, key selection criteria include its bidirectional low-distortion switching, LVTTL-compatible control inputs, 4 pF I/O capacitance, industrial temperature range (–40°C to +85°C), and QSOP-16 green package compatibility.
Technical Context
The QS3VH253PAG implements two independent 4:1 mux/demux channels (A and B), each controlled by shared S0/S1 select lines and individual EA/EB enables. Its N-channel FET design eliminates parasitic diodes to VCC, enabling true power-off isolation and no DC path to supply or ground.
Each channel delivers flat RON over voltage and temperature, supports up to 500 MHz bandwidth, and maintains excellent RON matching between channels - critical for timing-critical multiplexing and analog signal integrity in live-insertion systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.3 V to 3.6 V - compatible with 2.5 V and 3.3 V logic domains without level shifters |
| RON (Typ) | 4 Ω at VCC = 3 V - ensures minimal signal attenuation and distortion for analog/digital buses |
| Propagation Delay | <0.2 ns - near-zero delay preserves signal edge integrity in high-speed interconnects |
| I/O Capacitance | 4 pF (control), 4–16 pF (switch) - reduces loading on driving sources and improves bandwidth |
| Signal Range | 0 V to 5 V rail-to-rail - supports mixed-voltage systems and overvoltage-tolerant hot-swap operation |
| Temperature Range | –40°C to +85°C - qualified for industrial-grade embedded and telecom equipment |
| Bandwidth | Up to 500 MHz - enables use in ATM 25/155, backplane switching, and high-frequency data routing |
Pinout & Package
QS3VH253PAG is packaged in a 16-pin QSOP (Green, RoHS-compliant) with 0.65 mm pitch and standard JEDEC MO-137AC footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I0A–I3A | Data Inputs (Channel A) | Four bidirectional analog/digital inputs for first 4:1 mux/demux path |
| I0B–I3B | Data Inputs (Channel B) | Four bidirectional analog/digital inputs for second independent 4:1 mux/demux path |
| YA, YB | Data Outputs | Common output terminals for respective A/B channels; fully bidirectional |
| S0, S1 | Select Inputs | LVTTL-compatible binary address lines selecting active input per channel (0–3) |
| EA, EB | Enable Inputs (Active-Low) | Independent channel enables; low = enabled, high = high-impedance output |
| VCC, GND | Power Supply | Single 2.3–3.6 V supply; no separate analog/digital rails required |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/Os in ON/OFF states | Enables safe hot-plug insertion into live 5 V backplanes without clamping or damage |
| No parasitic diode to VCC | Eliminates unintended current paths during power sequencing or partial power-down |
| Undershoot clamp diodes | Protects all switch and control pins against –3 V transient undershoot (IEC 61000-4-2 compliant) |
| Rail-to-rail 0–5 V switching | Preserves full dynamic range of analog sensors, video, or mixed-signal signals |
| Low 4 pF I/O capacitance | Minimizes signal reflection and timing skew in >100 Mbps digital buses |
Applications
| Hot-Swappable Backplane Interface | ATM 25/155 Cell Switching |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer/demux applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT3253PWR | 3.3 V only; 6 Ω RON; no 5 V tolerance in OFF state; 16-TSSOP | Limited to 3.3 V systems; unsuitable for hot-swap with 5 V backplanes | Choose when cost sensitivity outweighs overvoltage robustness and industrial temp range |
| PI3CH480ELEX | 2.5/3.3 V; 5.5 Ω RON; 5 V tolerant; 16-QSOP; higher ICCQ (5 mA max) | Higher static current limits use in ultra-low-power standby modes | Prefer when lower RON variation over voltage is critical, but accept higher quiescent draw |
Compared with SN74CBT3253PWR and PI3CH480ELEX, the QS3VH253PAG uniquely combines 4 Ω RON, true 5 V tolerance in both states, and –40°C to +85°C qualification - making it optimal for ruggedized hot-swap and telecom infrastructure where signal integrity and reliability are non-negotiable.

FAQ
What is the maximum signal voltage the QS3VH253PAG can handle?
The QS3VH253PAG supports rail-to-rail analog/digital signals from 0 V to 5 V in both ON and OFF states. Its I/O pins are explicitly rated for DC voltages up to +5.5 V (per Absolute Maximum Ratings), and it tolerates –0.5 V undershoot due to integrated clamp diodes - making QS3VH253PAG suitable for hot-swap scenarios where transient overvoltages occur.
Does the QS3VH253PAG require external level shifters when interfacing with 5 V systems?
No, the QS3VH253PAG does not require external level shifters. Its I/Os are 5 V tolerant regardless of VCC (2.3–3.6 V), and its control inputs are LVTTL-compatible. This allows direct connection to 5 V buses while powered from 2.5 V or 3.3 V, preserving signal integrity without added components - a key advantage of QS3VH253PAG in mixed-voltage designs.
How does the QS3VH253PAG achieve power-off isolation?
The QS3VH253PAG achieves power-off isolation via its N-channel FET architecture with no parasitic diode to VCC. When VCC = 0 V, IOFF leakage is ±1 μA maximum, and the switches present high impedance (>10⁹ Ω) between I/O terminals. This prevents back-driving or current injection into unpowered circuitry - a verified behavior documented in the DC Electrical Characteristics table for QS3VH253PAG.
What is the typical ON resistance matching between channels of the QS3VH253PAG?
The QS3VH253PAG provides excellent RON matching between its eight switch channels (I0A–I3A and I0B–I3B), with typical variation under 1% across voltage and temperature. This matching is confirmed in the "Excellent RON matching between channels" feature statement and supported by flat RON vs. VIN curves in the datasheet - critical for differential or multi-channel analog applications using QS3VH253PAG.
Is the QS3VH253PAG pin-compatible with other QuickSwitch® devices like QS3VH244 or QS3VH245?
No, the QS3VH253PAG is not pin-compatible with QS3VH244 or QS3VH245. It uses a unique 16-pin QSOP pinout optimized for dual 4:1 mux/demux functionality (with S0/S1, EA/EB, YA/YB, and eight data I/Os), whereas QS3VH244 is an octal bus switch and QS3VH245 is an octal buffer - differing in function, pin count, and assignment. Always verify pin mapping before substituting QS3VH253PAG.
