Product details
Overview
QS4A215Q1G from Renesas Electronics (formerly IDT) is a high-performance CMOS six-channel SP4T analog multiplexer/demultiplexer with individual enables, 5Ω typical ON resistance, 700MHz -3dB bandwidth, and TTL-compatible control inputs. It operates from a single 5V supply across –40°C to +85°C and is used in high-speed video routing, telecom signal switching, and ATE systems.
For engineers reviewing the QS4A215Q1G datasheet, QS4A215Q1G pinout, QS4A215Q1G application, or QS4A215Q1G equivalent, key selection criteria include channel count (6× SP4T), break-before-make logic, ultra-low 9μA quiescent current, and QVSOP package compatibility for high-density PCB layouts.
Technical Context
The QS4A215Q1G integrates six independent SP4T switch blocks (AB, CD, EF), each with dual select lines (S0/S1) and dedicated enable inputs (EA–EF). Each block supports bidirectional analog signal routing with break-before-make switching to prevent output contention.
It delivers 700MHz bandwidth with –68dB crosstalk at 5MHz and –60dB off-isolation at same frequency, enabling HDTV-quality video and high-speed data acquisition. All channels share a single 5V supply and tolerate analog signals from –0.5V to VCC–1V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance | 5Ω typical - ensures low insertion loss & minimal signal attenuation in video/audio paths |
| Bandwidth (–3dB) | 700MHz - supports full-bandwidth HDTV (1080p60) and high-speed serial data routing |
| Crosstalk @ 5MHz | –68dB - prevents interference between active and inactive channels in multi-source systems |
| Off-Isolation @ 5MHz | –60dB - maintains signal integrity when channels are disabled in sensitive measurement setups |
| Transition Time | 6ns max - enables fast switching in time-critical ATE and packet-switched telecom applications |
| Quiescent Current | 9μA - allows battery-powered instrumentation and remote sensor nodes without significant standby drain |
| Supply Voltage | Single 5V ±5% - simplifies power design by eliminating dual-rail or level-shifting requirements |
Pinout & Package
The QS4A215Q1G is packaged in a 48-pin QVSOP (Quad Very Small Outline Package), offering reduced pin inductance and shorter signal paths versus SOIC or PDIP-critical for preserving 700MHz bandwidth and minimizing ground bounce in high-speed layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I0A–I3A, I0B–I3B | Demux Inputs / Mux Outputs | Four analog I/O ports per AB block; bidirectional operation supports mux or demux topology |
| YA, YB | Mux Outputs / Demux Inputs | Common path for AB block; connects to selected Ix port based on S0AB/S1AB state |
| S0AB, S1AB | Digital Select Inputs | 2-bit binary address controlling which of four Ix ports connects to YA/YB (00–11) |
| EA, EB | Block Enable Inputs | Active-low enables; disabling EA or EB forces YA or YB into high-impedance state |
| VCC (Pins 22, 23, 24) | Power Supply | Three distributed 5V supply pins reduce IR drop and improve noise immunity across wide bandwidth |
| GND (Pins 8, 16, 27) | Ground Reference | Three dedicated ground pins minimize return-path inductance and stabilize high-frequency switching |
Key Features
| Feature | Design Value |
|---|---|
| Break-Before-Make Switching | Prevents momentary short-circuit between input sources during channel transitions-essential for protecting video drivers and ADC front-ends |
| Ultra-Low Charge Injection (1.5pC) | Minimizes voltage glitch on sampled nodes-critical for precision data acquisition and sample-and-hold circuits |
| Low ON-Capacitance (20pF) | Reduces loading on high-impedance signal sources and preserves rise/fall times in >100MHz applications |
| TTL-Compatible Control | Accepts standard 0.8V/2.0V logic thresholds-eliminates need for level shifters when interfacing with FPGA or microcontroller GPIO |
| Individual Channel Enables | Per-block enables (EA–EF) allow dynamic reconfiguration of signal paths without affecting other active channels |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1308RTER | 8-channel SP8T, 4.5Ω rDS(ON), 300MHz bandwidth, 1.8–5.5V supply | Higher channel density but lower bandwidth; supports lower-voltage logic interfaces | Choose TMUX1308RTER when consolidating more signals per chip outweighs need for >500MHz video bandwidth |
| ADG1408YRUZ | 8-channel SP8T, 4.7Ω rDS(ON), 170MHz bandwidth, ±5V dual supply required | Requires dual-rail supply; optimized for precision DC-coupled instrumentation, not high-speed AC signals | Choose ADG1408YRUZ for low-drift, rail-to-rail analog front-ends where bandwidth <200MHz suffices |
Compared with TMUX1308RTER and ADG1408YRUZ, the QS4A215Q1G uniquely balances 700MHz bandwidth, six independent SP4T blocks, and single 5V operation-making it optimal for HDTV routing and high-speed ATE where both speed and channel granularity matter.

FAQ
What is the maximum analog signal voltage range supported by the QS4A215Q1G?
The QS4A215Q1G supports an analog input voltage range of –0.5V to VCC–1V. With a nominal 5V supply, this translates to –0.5V to +4.0V, allowing safe handling of bipolar video sync pulses and DC-coupled audio signals without clamping or distortion. This range is validated across the full industrial temperature range (–40°C to +85°C).
Does the QS4A215Q1G support bidirectional signal flow?
Yes, the QS4A215Q1G supports fully bidirectional analog signal routing. Each SP4T block (e.g., AB, CD, EF) operates identically in mux or demux mode-the same Ix and Yx pins serve as inputs or outputs depending on signal direction and enable state. This is confirmed by its functional block diagram, pin descriptions, and "Can be used as multiplexer or demultiplexer" feature statement.
What is the purpose of the three VCC and three GND pins on the QS4A215Q1G?
The QS4A215Q1G features three VCC (pins 22, 23, 24) and three GND (pins 8, 16, 27) connections to minimize power distribution impedance and ground loop inductance. This layout reduces voltage droop and ground bounce during fast 6ns transitions-critical for maintaining signal integrity at 700MHz and preventing coupling between high-speed analog and digital sections.
How does the break-before-make feature operate in the QS4A215Q1G?
The QS4A215Q1G implements hardware-enforced break-before-make switching: when select inputs change, the previously connected path is fully disconnected before the new path closes. This prevents momentary shorts between input sources-verified by internal control logic design and explicitly stated in the device description-and protects downstream circuitry such as video line drivers or ADC inputs.
Is the QS4A215Q1G RoHS-compliant and halogen-free?
Yes, the QS4A215Q1G is manufactured in a green (RoHS-compliant and halogen-free) process, as indicated by the "Q1G" suffix in the ordering code and confirmed in the "Ordering Information" section of the datasheet. The QVSOP package uses lead-free terminations and meets JEDEC J-STD-020 moisture sensitivity level 3 requirements.
