Product details

Overview

PI3CH360LEX from Diodes Incorporated (acquired Pericom Semiconductor) is a 3-channel, 2:1 analog multiplexer/demultiplexer with enable-low control, 500 MHz bandwidth, 4–8 Ω on-resistance, and rail-to-rail signal switching capability across 1.8V/2.5V/3.3V supplies. It serves as a high-speed signal path selector in PCIe Gen2/3 switch fabrics and hot-pluggable backplane interfaces.

For engineers reviewing the PI3CH360LEX datasheet, PI3CH360LEX pinout, PI3CH360LEX application, or PI3CH360LEX equivalent, key selection criteria include sub-0.3 ns propagation delay, 5 V I/O tolerance during power-off, 8 kV HBM ESD rating, and TSSOP-16 package compatibility with high-density PCB layouts.

Technical Context

The PI3CH360LEX implements three independent bidirectional 2:1 analog switches controlled by a shared low-active EN and a single S select line. Each switch exhibits near-zero intrinsic propagation delay (<0.3 ns typical), with bandwidth limited only by RC time constant of R_ON (≤8 Ω) and load capacitance (e.g., 10 pF).

Its beyond-rail switching supports 0–5 V signal pass-through at 3.3 V V_CC, 0–3.3 V at 2.5 V V_CC, and 0–2.5 V at 1.8 V V_CC. The device maintains 5 V I/O tolerance regardless of supply state-critical for hot-insertion in telecom/datacom backplanes.

Key Specifications

Parameter	Value and Actual Design Meaning
Bandwidth	500 MHz – Enables full-speed switching of PCIe Gen2 (5 GT/s) and USB 2.0 (480 Mbps) signals without attenuation.
On-Resistance (R_ON)	4–8 Ω (typ. 5 Ω @ 3.3 V) – Minimizes insertion loss and signal distortion in high-fidelity analog/digital paths.
Propagation Delay	<0.3 ns (typ.) – Adds negligible timing skew in synchronous multi-lane systems like DDR memory routing or display link muxing.
I/O Voltage Tolerance	−0.5 V to +6.0 V – Allows safe operation during hot-plug events where backplane voltages transiently exceed V_CC.
Supply Range	1.8 V / 2.5 V / 3.3 V – Supports mixed-voltage system integration without level-shifting circuitry.
ESD Rating	8 kV HBM – Meets industrial-grade robustness requirements for board-level handling and field deployment.
Operating Temp	−40°C to +85°C – Qualified for extended-temperature industrial and telecom infrastructure applications.

Pinout & Package

Package: 16-pin TSSOP (173-mil wide, Pb-free & Green compliant, JEDEC MO-153).

Pin/Terminal	Circuit Role	Design Meaning
1	S (Select)	Global channel select: L = route IA0/IB0/IC0 to YA/YB/YC; H = route IA1/IB1/IC1.
4,5,6	YA, YB, YC	Three bidirectional analog outputs-common node per channel, driven high-Z when disabled.
9–14	IA0, IB0, IC0, IA1, IB1, IC1	Two sets of three input channels-fully independent, no crosstalk between channels.
15	EN (Enable)	Active-low global enable: L = functional; H = all outputs forced high-Z (no leakage path).
16	V_CC	Single supply pin supporting 1.8 V / 2.5 V / 3.3 V operation; powers internal logic and switch bias.
8	GND	Analog/digital ground reference-must be low-impedance connection to minimize noise coupling.
2,3,7	NC	No-connect pins-must remain unconnected per datasheet; not internally bonded.

Key Features

Feature	Design Value
Near-zero propagation delay	Sub-0.3 ns typical adds no measurable timing skew in high-speed serial lanes or parallel buses.
Beyond-rail signal switching	Supports 0–5 V analog/digital signals at 3.3 V V_CC, eliminating external clamping diodes in mixed-voltage backplanes.
Hot-insertion capable	Withstands 6 V transients for ≤20 ns at inputs-enables safe live insertion into powered telecom chassis.
5 V I/O tolerant in OFF/ON states	Allows direct interface to legacy 5 V logic without level shifters, even when V_CC = 1.8 V or unpowered.
Low on-resistance variation	R_ON flatness <±0.5 Ω across 0–3.3 V input range ensures consistent signal integrity in video/audio routing.

Applications

PCIe Switch Fabric Muxing

Hot-Pluggable Backplane Interface

Use Scenario: Selecting between two upstream PCIe Gen3 root complexes feeding a single downstream endpoint in modular server blades.

IC Role / Device Role / Timing Role: Bidirectional 2:1 analog mux per lane pair, preserving differential signaling integrity and sub-nanosecond timing alignment.

Use Value: Enables failover redundancy without signal degradation-RON ≤8 Ω and BW = 500 MHz maintain eye diagram compliance at 8 GT/s.

Use Scenario: Routing control and status signals between a hot-swappable line card and fixed shelf controller in carrier-grade routers.

IC Role / Device Role / Timing Role: Level-tolerant signal switch enabling safe insertion while backplane remains powered at +12 V.

Use Value: 6 V I/O tolerance and 8 kV HBM ESD prevent latch-up or damage during mechanical mating under power.

Multi-Source Display Link Routing

DDR Memory Channel Selection

Use Scenario: Dynamically selecting between embedded GPU and discrete GPU outputs to a single HDMI/DP sink in thin-client workstations.

IC Role / Device Role / Timing Role: High-bandwidth analog switch for TMDS/DisplayPort AUX and main-link differential pairs.

Use Value: 500 MHz bandwidth preserves pixel clock fidelity up to 4K@60 Hz; R_ON flatness prevents gamma shift across color channels.

Use Scenario: Isolating two DDR4 memory controllers sharing a common DIMM slot in dual-CPU server motherboards.

IC Role / Device Role / Timing Role: Low-skew, low-capacitance switch for address/command/control lines (not data strobes).

Use Value: Sub-0.3 ns t_PLH/t_PHL avoids setup/hold violations; high off-isolation (>60 dB) prevents crosstalk between active/inactive controllers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TS3USB30E	Single-channel, 3.3 V only, 500 MHz BW, 6 Ω R_ON, no 5 V I/O tolerance	Limited to point-to-point USB 2.0 switching; unsuitable for hot-plug or mixed-voltage backplanes	Choose for cost-sensitive USB-only designs where voltage margin and hot-swap are not required.
ADG732BRUZ	32-channel, 1.8 V/3.3 V, 200 MHz BW, 4 Ω R_ON, −0.3 V to +5.5 V I/O tolerance	Higher channel count but lower bandwidth-optimized for precision instrumentation, not high-speed serial links	Prefer for multi-signal test equipment or sensor matrix routing where bandwidth <300 MHz suffices.

Compared with TS3USB30E and ADG732BRUZ, the PI3CH360LEX uniquely combines triple-channel 2:1 topology, 500 MHz bandwidth, 5 V I/O tolerance, and hot-plug resilience-making it the only fit for PCIe/DDR signal routing in modular telecom infrastructure.

FAQ

What is the maximum allowable input voltage when V_CC = 0 V?

The PI3CH360LEX supports −0.5 V to +6.0 V DC input voltage regardless of V_CC state. With V_CC unpowered, the 5 V I/O tolerance remains fully valid-enabling safe hot-insertion into live backplanes where input pins may see transient overvoltage before supply stabilization.

Can the PI3CH360LEX be used to switch differential PCIe signals?

Yes-each channel handles one differential pair (e.g., IA0+/IA0− → YA+/YA−) as two independent single-ended paths. Its 500 MHz bandwidth, <0.3 ns propagation skew between Y/In pins, and 60 dB off-isolation preserve PCIe Gen2/3 eye diagrams when layout maintains matched trace lengths and controlled impedance.

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

No-EN and S have CMOS-compatible input thresholds (VIH ≥2.0 V @ 3.3 V, VIL ≤0.8 V) and ±1 μA leakage. Direct FPGA/CPLD GPIO drive is sufficient; adding external resistors risks degrading edge rates and increasing enable/disable times beyond specified 1.5–25 ns range.

How does the 8 kV HBM ESD rating translate to system-level robustness?

The 8 kV HBM rating reflects per-pin robustness against human-body discharge events during handling and assembly. In-system protection requires additional TVS diodes for sustained transients (e.g., IEC 61000-4-2 contact discharge), but this rating ensures the PI3CH360LEX survives standard ESD-safe manufacturing without latent damage or parameter shift.
