Product details
Overview
PI3CH480LEX from Diodes Incorporated is a 4-channel, 2:1 analog multiplexer/demultiplexer with tri-state outputs, designed for high-bandwidth signal routing in 1.8V/2.5V/3.3V systems. It delivers 500 MHz bandwidth, <0.3 ns propagation delay, 4–6 Ω on-resistance, and rail-to-rail switching (0–5V with 3.3V supply), enabling clean signal pass-through in hot-plug-capable PCIe, USB, and LVDS interconnects.
For engineers reviewing the PI3CH480LEX datasheet, PI3CH480LEX pinout, PI3CH480LEX application, or PI3CH480LEX equivalent, key selection criteria include its 500 MHz –3dB bandwidth, 8kV HBM ESD rating, enable-low logic control, 5V I/O tolerance across all supply voltages, and support for industrial temperature range (–40°C to +85°C).
Technical Context
The PI3CH480LEX implements four independent bidirectional 2:1 analog switches controlled by a single select line (S) and an active-low enable (EN). Each switch features near-zero propagation delay and no ground-bounce noise generation due to its low-impedance CMOS architecture.
It supports rail-to-rail analog input ranges beyond supply rails-0–5V with 3.3V VCC, 0–3.3V with 2.5V VCC-and maintains 5V I/O tolerance in both ON and OFF states, making it suitable for mixed-voltage domain bridging without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3dB) | 500 MHz - preserves integrity of high-speed digital and analog signals up to PCIe Gen1/USB 2.0 data rates |
| On-Resistance (RON) | 4–6 Ω at 3.3V - minimizes insertion loss and signal distortion in impedance-sensitive paths |
| Propagation Delay | <0.3 ns - adds negligible timing skew in synchronous multi-lane routing applications |
| Supply Voltage Range | 1.8V / 2.5V / 3.3V - enables direct integration into low-voltage FPGA I/O banks and SoC interfaces |
| I/O Tolerance | 5V tolerant with any supply voltage - allows safe interfacing with legacy 5V peripherals without external protection |
| ESD Rating | 8 kV HBM - meets industrial system-level ESD robustness requirements for backplane and connector-facing circuits |
| Operating Temperature | –40°C to +85°C - qualified for deployment in uncontrolled industrial and telecom equipment environments |
Pinout & Package
PI3CH480LEX is supplied in a 16-pin TSSOP (173-mil wide) package with exposed thermal pad grounded internally. Pin functions are validated per Diodes DS40329 Rev 5-2.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S | Select line controlling channel A–D between IAx/IBx inputs (x=0,1); active-HI, synchronous with EN |
| 2,3,5,6,11,10,14,13 | IA0–ID1 | Eight bidirectional analog inputs (two per channel); tolerate 0–5V regardless of VCC |
| 4,7,9,12 | YA–YD | Four bidirectional analog outputs; tri-state when EN = HIGH or S invalid |
| 8 | GND | Analog/digital ground reference; connects to PCB ground plane via exposed pad |
| 15 | EN | Active-low global enable; disables all switches and places outputs in high-impedance state |
| 16 | VCC | Positive supply (1.8V/2.5V/3.3V); powers internal logic and switch bias circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports 0–5V input swing with 3.3V supply-enables direct connection to 5V-tolerant microcontrollers without level translation |
| Hot-insertion capability | Withstands transient overvoltage during live backplane insertion; meets telecom hot-swap reliability requirements |
| Tri-state outputs with EN control | Prevents bus contention in shared signal routing; essential for dynamic reconfiguration in FPGA-based test equipment |
| Beyond-rail signal handling | Accepts input voltages exceeding VCC (up to 5V) while powered-critical for mixed-supply system interoperability |
| Low on-capacitance (8.4 pF typ) | Reduces loading on high-frequency source drivers; maintains signal edge fidelity in >200 MHz applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3A227EYZR | Single 4:1 mux (not 4×2:1), 300 MHz BW, 0.75 Ω RON, 1.65–3.6V supply only | Lacks independent channel control and 5V I/O tolerance; unsuitable for mixed-voltage backplane use | Prefer PI3CH480LEX when per-channel select logic, rail-to-rail operation, or hot-plug resilience is required |
| ADG732BRUZ | 32-channel 1:1 mux, 200 MHz BW, 4 Ω RON, 1.8–5.5V supply, no 5V I/O tolerance in OFF state | Higher channel count but lower bandwidth and no OFF-state 5V tolerance-requires external clamping for hot-swap | Choose PI3CH480LEX for compact 4-channel high-BW routing with guaranteed 5V fault immunity |
Compared with TS3A227EYZR and ADG732BRUZ, the PI3CH480LEX uniquely combines per-channel 2:1 select logic, 500 MHz bandwidth, and unconditional 5V I/O tolerance in both ON/OFF states-making it optimal for reconfigurable high-speed interconnects requiring zero-latency switching and hot-plug safety.

FAQ
What supply voltage options does the PI3CH480LEX support?
The PI3CH480LEX operates from 1.8V, 2.5V, or 3.3V nominal supplies. Its I/O pins remain 5V tolerant regardless of selected VCC, and analog input range extends beyond rails-0–5V with 3.3V supply, 0–3.3V with 2.5V supply-enabling flexible mixed-voltage system integration without level shifters.
Does the PI3CH480LEX require external pull-up or pull-down resistors on control pins?
No external biasing is required. The EN and S inputs have CMOS-compatible thresholds (VIH ≥ 2.0V @ 3.3V supply; VIL ≤ 0.8V) and leakage current ≤ ±1 μA. Driving EN directly from FPGA I/O or microcontroller GPIO-rail-to-rail or with series resistor-is sufficient for reliable operation across temperature.
How does the PI3CH480LEX handle hot-insertion transients?
The device withstands 5V I/O stress in both ON and OFF states and features 8kV HBM ESD protection. Its internal clamp diodes and latch-up immunity (>200 mA per JESD17) allow safe operation during live backplane insertion where transient overvoltages may occur-no external TVS diodes needed for standard telecom hot-swap profiles.
Can the PI3CH480LEX be used for bidirectional analog signal routing?
Yes-the PI3CH480LEX is fully bidirectional: each switch conducts equally well from input to output or output to input. Its symmetrical RON (4–6 Ω), low capacitance (8.4 pF typ), and absence of body-diode conduction make it suitable for analog audio, sensor multiplexing, and bidirectional data bus applications up to 500 MHz.
