Product details
Overview
PI5A100QEX from Diodes Incorporated is a precision quad single-pole double-throw (4SPDT) CMOS analog switch operating from +2V to +6V single supply, featuring 8ns typical turn-on time, 6Ω typical on-resistance at 5V, <2Ω on-resistance flatness, and -100dB crosstalk at 10MHz - deployed in RGB-to-composite video routing and audio muting circuits.
For engineers reviewing the PI5A100QEX datasheet, PI5A100QEX pinout, PI5A100QEX application, or PI5A100QEX equivalent, key selection criteria include rail-to-rail analog signal range, channel-to-channel on-resistance matching (≤2Ω), charge injection (10pC typ.), high-current capability (>100mA per channel), and industrial temperature support (-40°C to +85°C).
Technical Context
The PI5A100QEX implements four independent SPDT switches with enable-controlled high-impedance state, each supporting bidirectional analog conduction and rail-to-rail voltage blocking in the off state. Its decoder-based logic accepts TTL/CMOS-compatible inputs and guarantees operation across +3.3V and +5V supplies.
Designed for low-distortion signal routing, it delivers 230MHz -3dB bandwidth, <0.2% THD under 10kΩ load, and low leakage (<80nA at 25°C) - enabling clean switching of audio, video, and data signals without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +6V single supply - supports battery-powered and mixed-voltage systems without dual-rail generation. |
| On-Resistance (RON) | 8Ω max at +5V - ensures minimal insertion loss and signal attenuation in audio/video paths. |
| On-Resistance Matching | ≤2Ω max between channels - critical for balanced differential or multi-path signal routing. |
| Turn-On Time (tON) | 15ns max - enables high-speed multiplexing in digital video and LAN switching applications. |
| Crosstalk | -100dB at 10MHz - prevents interference between adjacent switched channels in dense PCB layouts. |
| Bandwidth (-3dB) | 230MHz - supports full-bandwidth switching of HD video (720p/1080i) and fast data signals. |
| Charge Injection | 10pC typ. - reduces glitch-induced artifacts during switching in precision ADC/DAC interfaces. |
Pinout & Package
PI5A100QEX is housed in a 16-pin QSOP (Q) package with 0.65mm lead pitch, 3.9mm body width, and industrial-grade moisture sensitivity level (MSL3). Pin layout follows standard analog switch conventions with dedicated COM/NO/NC terminals per channel and shared EN and VCC/GND rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 7 | COM1–COM4 | Common analog terminals - bidirectional current path for each SPDT switch. |
| 2, 4, 6, 8 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = 0 and EN = 0. |
| 9, 11, 13, 15 | NO1–NO4 | Normally open analog terminals - conduct to COM when IN = 1 and EN = 0. |
| 10, 12, 14, 16 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; active-high logic selects NO path. |
| 16 | VCC | Positive supply rail - powers internal logic and switch driver circuitry. |
| 8 | GND | Ground reference - common return for analog and digital domains. |
| 16 | EN | Global enable input - high disables all switches into high-Z state, overriding IN states. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal range | Supports full-swing AC/DC signals from GND to VCC - eliminates level-shifting in audio and video front-ends. |
| Low on-resistance flatness | <2Ω typ. variation over full analog range - preserves amplitude linearity in gain-critical paths. |
| High off-isolation | -57dB at 10MHz - maintains signal integrity in multi-source routing where channel separation is essential. |
| TTL/CMOS logic compatibility | VIH = 2.4V min, VIL = 0.8V max - interoperates directly with FPGA, MCU, and ASIC GPIO without level translators. |
| Low power consumption | 1µA max ICC - extends battery life in portable instrumentation and handheld test equipment. |
Applications
| RGB-to-Composite Video Routing | Audio Muting Circuit |
|---|---|
Use Scenario: Selecting between SVHS, composite, and RGB outputs from a single video source using an RGB-to-composite decoder. IC Role / Device Role / Timing Role: Analog signal path selector - routes baseband Y/C or CVBS signals with minimal insertion loss and no added buffering. Use Value: Eliminates need for external op-amp buffers due to 230MHz bandwidth and <0.2% distortion, reducing BOM count and board area. | Use Scenario: Suppressing pop/click noise during power-up, power-down, and source switching in stereo headphone amplifiers. IC Role / Device Role / Timing Role: Ground-switching muting element - connects DAC outputs to GND during transitions using EN and IN control.

IC Role / Device Role / Timing Role: High-speed analog/data path switch - routes MDI/MDI-X or auxiliary monitoring signals with low crosstalk. Use Value: -100dB crosstalk at 10MHz prevents coupling between adjacent 10/100BASE-T lanes, ensuring signal fidelity during diagnostics. | Use Scenario: Channel selection in portable oscilloscopes, multimeters, and sensor interface modules powered by Li-ion batteries. IC Role / Device Role / Timing Role: Low-power analog multiplexer - enables sequential sampling of multiple sensors while minimizing standby current. Use Value: 1µA ICC and +2V minimum supply allow operation down to single-cell battery voltage, extending runtime without voltage boosting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Higher RON (15Ω typ. @5V), slower tON (25ns), wider SOIC only - no QSOP option. | Limited to space-tolerant industrial boards; unsuitable for compact portable designs requiring QSOP footprint. | Choose when higher ESD tolerance (±15kV HBM) is prioritized over speed and package size. |
| ADG1419BRUZ | Lower RON (0.9Ω typ.), but requires ±15V dual supply or +12V single supply - incompatible with +3.3V systems. | Restricted to high-precision instrumentation with available dual-rail supplies; not viable for battery-powered +3.3V logic. | Choose only if ultra-low on-resistance and THD <0.001% are mandatory, and supply architecture permits. |
Compared with MAX4617ESE+ and ADG1419BRUZ, PI5A100QEX uniquely balances low RON (8Ω), QSOP packaging, +2V–+6V single-supply operation, and 8ns switching - making it optimal for compact, battery-aware video/audio routing where supply flexibility and layout density matter.

FAQ
What is the maximum analog signal voltage the PI5A100QEX can switch?
The PI5A100QEX supports rail-to-rail analog signals from GND to VCC. With a +5V supply, it handles 0V to +5V; with +3.3V, 0V to +3.3V. Absolute maximum analog voltage is VCC +2V or -0.5V relative to GND - clamped by internal diodes, but sustained operation beyond rails risks damage.
Can the PI5A100QEX operate reliably at +2.5V supply?
Yes - the datasheet specifies guaranteed operation from +2V to +6V. At +2.5V, RON increases to ~20Ω (typ.) and tON extends to ~30ns, but all logic thresholds (VIH/VIL) and leakage remain within spec. It is validated for battery-powered systems with aging or drooping supply rails.
How does the EN pin interact with individual IN control signals?
EN is an active-high global enable: when EN = high, all four switches enter high-impedance state regardless of IN states. When EN = low, each switch responds independently to its IN signal - selecting NO (IN=1) or NC (IN=0). This allows synchronized disable across all channels without reconfiguring individual controls.
Is the PI5A100QEX pin-compatible with the PI5A100WEX?
Yes - both share identical 16-pin pinout and electrical specifications. The only difference is package: QEX uses QSOP (3.9mm width), WEX uses SOIC-W (7.5mm width). Footprint and schematic symbols differ, but logic behavior, timing, and analog performance are identical across both variants.
