Product details

Overview

PI3CH480LE 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 –3dB bandwidth, <0.3 ns propagation delay, 4–8 Ω on-resistance, and rail-to-rail switching (0–5V with 3.3V supply), enabling low-distortion video, USB 2.0, and PCIe Gen1 signal switching.

For engineers reviewing the PI3CH480LE datasheet, PI3CH480LE pinout, PI3CH480LE application, or PI3CH480LE equivalent, key selection criteria include hot-plug capability, 5V I/O tolerance across all supply voltages, sub-10 ns enable/disable timing, and compatibility with TSSOP-16, QSOP-16, and UQFN3x3-16 packages.

Technical Context

The PI3CH480LE implements four independent bidirectional 2:1 analog switches controlled by a single select (S) and active-low enable (EN) input per channel group. Each switch supports rail-to-rail analog voltage swing up to 5V with 3.3V VCC, and maintains 5V I/O tolerance regardless of power state.

Its architecture eliminates ground bounce and adds no measurable propagation delay beyond RC time constant (~0.3 ns for 10 pF load). Switching is characterized at three supply rails (1.8V/2.5V/3.3V), with on-resistance, crosstalk (–60 dB), and off-isolation (–60 dB) specified across full industrial temperature range (–40°C to +85°C).

Key Specifications

Parameter	Value and Actual Design Meaning
Bandwidth	500 MHz –3dB; supports HDMI 1.4, USB 2.0, and PCIe Gen1 differential signaling without attenuation
On-Resistance	4–8 Ω typical; ensures minimal insertion loss and signal distortion in high-speed analog paths
Propagation Delay	<0.3 ns; contributes negligible timing skew in synchronous multi-lane interfaces
Supply Voltage Range	1.8V/2.5V/3.3V ±10%; enables drop-in use across legacy and low-power logic domains
I/O Tolerance	5V tolerant on all pins with VCC OFF or ON; simplifies level-shifting and hot-swap design
ESD Protection	8 kV HBM; meets IEC 61000-4-2 Level 3 for robust board-level ESD immunity
Operating Temperature	–40°C to +85°C; qualified for industrial-grade embedded and telecom equipment

Pinout & Package

PI3CH480LE is available in three RoHS-compliant, lead-free packages: 16-pin TSSOP (L), 16-pin QSOP (Q), and 16-pin UQFN3×3 (ZHD). All variants share identical pin functionality and thermal pad grounding (center pad = GND).

Pin/Terminal	Circuit Role	Design Meaning
S	Select Input	Common control for all 4 channels; selects IA0/IB0/IC0/ID0 (S=L) or IA1/IB1/IC1/ID1 (S=H)
EN	Active-Low Enable	Global enable; drives all Y outputs to high-impedance when high
IA0–ID1 (8 pins)	Analog Inputs	Two input pairs per channel (e.g., IA0/IA1 → YA); bidirectional signal path
YA–YD (4 pins)	Analog Outputs	Channel outputs; tri-state capable; support hot-plug isolation when EN=H
VCC	Power Supply	Single supply pin; powers internal logic and switch bias; accepts 1.8V/2.5V/3.3V
GND	Ground Reference	Signal and power return; center pad in UQFN must be soldered to PCB ground plane

Key Features

Feature	Design Value
Near-zero propagation delay	0.3 ns max; preserves signal integrity in >200 Mbps serial links without timing compensation
Rail-to-rail switching	0–5V analog swing with 3.3V VCC; eliminates external level shifters in mixed-voltage systems
Hot-insertion capability	Withstands 6V transient on I/O pins during live backplane insertion; prevents latch-up during system expansion
5V I/O tolerance	Valid with VCC powered or unpowered; enables safe interface to legacy 5V peripherals during power sequencing
Low quiescent current	0.2–1.5 mA ICC across supply range; reduces standby power in battery-backed or always-on modules

Applications

USB 2.0 Signal Routing

HDMI Source Selection

Use Scenario: Dynamic switching between dual USB 2.0 hosts (e.g., laptop and docking station) sharing a single peripheral.

IC Role / Device Role / Timing Role: Bidirectional 2:1 analog mux for D+/D– differential pairs; preserves 480 Mbps eye diagram integrity.

Use Value: Enables seamless host handover without re-enumeration; 500 MHz bandwidth avoids signal degradation at 240 MHz fundamental frequency.

Use Scenario: Consumer AV receiver selecting among multiple HDMI sources (Blu-ray, game console, streaming box) before output to display.

IC Role / Device Role / Timing Role: High-fidelity analog switch for TMDS clock and data lanes; supports 720p/1080p resolution switching.

Use Value: Maintains <0.3 ns inter-pair skew across all 4 channels; prevents pixel jitter or color banding during source change.

PCIe Gen1 Lane Multiplexing

Industrial Camera Interface

Use Scenario: FPGA-based test equipment sharing limited PCIe root complex lanes across multiple daughterboards.

IC Role / Device Role / Timing Role: Low-latency 2:1 mux for PCIe TX/RX differential pairs; operates under 3.3V core logic supply.

Use Value: Sub-10 ns enable/disable time allows lane reconfiguration within PCIe L0s exit latency budget; 4 Ω R_ON minimizes insertion loss.

Use Scenario: Embedded vision system aggregating image data from four CMOS sensors into one MIPI CSI-2 receiver.

IC Role / Device Role / Timing Role: Analog front-end signal selector for parallel LVDS or sub-LVDS sensor outputs prior to serializer.

Use Value: –60 dB crosstalk prevents ghosting between adjacent camera feeds; industrial temp rating ensures reliability in factory-floor enclosures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TS3A227E	Lower bandwidth (300 MHz), higher R_ON (8–12 Ω), 1.65–3.6V only; no 5V I/O tolerance	Not suitable for 5V-tolerant hot-swap or HDMI 1080p; better for cost-sensitive 3.3V-only designs	Choose if supply is strictly ≤3.6V and bandwidth ≤300 MHz suffices; avoid for backplane or mixed-voltage systems
ADG732	Higher R_ON (4.5–7.5 Ω), lower bandwidth (200 MHz), 1.8–5.5V supply; no guaranteed 5V I/O tolerance in OFF state	Limited to lower-speed industrial I/O; lacks hot-plug robustness and rail-to-rail analog swing at 3.3V	Prefer for precision DC-coupled switching where bandwidth <200 MHz; not recommended for USB/HDMI/PCIe

Compared with TS3A227E and ADG732, PI3CH480LE uniquely combines 500 MHz bandwidth, 5V I/O tolerance in both ON/OFF states, and rail-to-rail operation at 3.3V - making it the only option qualified for hot-pluggable, multi-standard digital video and high-speed serial routing.

FAQ

Is PI3CH480LE compatible with 5V logic control signals while operating at 1.8V VCC?

Yes. All logic inputs (S and EN) tolerate up to 3.6V regardless of VCC level, and analog I/O pins withstand 5V even when VCC is unpowered. This enables direct interfacing with 5V microcontrollers or FPGAs without level shifters, supporting flexible power domain partitioning in mixed-voltage systems.

What is the maximum continuous current per switch channel?

The absolute maximum DC output current is 120 mA per channel, verified per datasheet Section "Maximum Ratings". However, sustained operation above 48 mA at 1.8V or 64 mA at 3.3V increases on-resistance variation and thermal stress; design guidance recommends limiting steady-state current to ≤40 mA for long-term reliability.

Does PI3CH480LE require external pull-up or pull-down resistors on S or EN pins?

No. The device has internal weak pull-downs on EN and no internal bias on S; however, external 10–100 kΩ pull-down on EN is recommended for fail-safe high-impedance default state during power-up. S should be actively driven - floating S causes undefined channel selection and may induce leakage or noise coupling.

How does the UQFN3x3-16 (ZHD) package differ electrically from TSSOP-16 (L)?

Electrically identical: same pinout, timing, R_ON, bandwidth, and thermal specs. Mechanically, ZHD offers 3×3 mm footprint (vs. 5×4.4 mm TSSOP), lower parasitic inductance, and enhanced thermal dissipation via exposed center pad - critical for high-density PCBs in space-constrained USB or HDMI modules where signal integrity and thermal headroom are prioritized.
