Product details
Overview
PI3CH360LE from Pericom Semiconductor is a low-voltage, high-bandwidth 3-channel 2:1 multiplexer/demultiplexer with 3-state outputs, designed for signal routing in high-speed digital systems. It operates at 2.5V or 3.3V supply, delivers 500 MHz –3dB bandwidth, features 4–8 Ω on-resistance, near-zero propagation delay (0.3 ns), and supports rail-to-rail switching with 5V I/O tolerance.
For engineers reviewing the PI3CH360LE datasheet, PI3CH360LE pinout, PI3CH360LE application, or PI3CH360LE equivalent, key selection criteria include its 3.3V/2.5V dual-supply compatibility, sub-1ns enable/disable timing, 200–500 MHz bandwidth scalability, ESD robustness (2 kV HBM), and hot-insertion capability in backplane interfaces.
Technical Context
The PI3CH360LE implements three independent bidirectional analog/digital switches controlled by a shared select (S) and enable (EN) logic interface. Each channel routes one of two inputs (IAx/IBx) to its output (Yx) with no added ground bounce or propagation delay beyond RC time constant (~0.3 ns with 10 pF load).
It uses advanced sub-micron CMOS process to achieve 5Ω typical on-resistance at 3.3V, 7Ω at 2.5V, and maintains <±1 µA leakage across –40°C to +85°C. Input clamping diodes support 6.0V absolute max input voltage regardless of VCC, enabling safe hot insertion in telecom backplanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 200–500 MHz: Supports HDMI 1.4 pixel clock, PCIe Gen1, and DDR2 address/control routing without signal integrity loss. |
| On-Resistance (RON) | 4–8 Ω (typ.): Ensures minimal voltage drop and power loss when routing 120 mA peak signals at 3.3V/2.5V supplies. |
| Propagation Delay | 0.3 ns (typ.): Adds negligible timing skew in synchronous bus switching applications such as memory multiplexing. |
| I/O Voltage Tolerance | –0.5 V to +6.0 V: Enables interfacing with 5V legacy logic while powered from 2.5V/3.3V rails-no level shifters required. |
| Enable/Disable Time | 1.5–9.0 ns: Allows fast channel reconfiguration in real-time signal path management (e.g., test equipment front-end switching). |
| Off-Isolation / Crosstalk | –60 dB: Prevents signal coupling between inactive channels in multi-source video/audio routing systems. |
| ESD Protection | 2 kV HBM: Meets industrial handling requirements without external protection components in board-level assembly. |
Pinout & Package
PI3CH360LE is packaged in a Pb-free, green 16-pin TSSOP (173-mil width, 0.65 mm pitch), with exposed thermal pad (pin 17 not present; 16-pin count confirmed per ordering code). Pinout validated per official Pericom datasheet PS8727A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 (IA0–IA2) | Data Input A | First input pair for each of three independent 2:1 switch channels; accepts DC to 500 MHz signals. |
| 4, 5, 6 (IB0–IB2) | Data Input B | Second input pair per channel; selectable via S pin; electrically identical to IAx pins. |
| 7, 8, 9 (YA–YC) | Data Output | Switched outputs; tri-stated when EN = HIGH; driven low/high only when enabled and selected. |
| 10 (GND) | Ground Reference | Primary return path for all internal logic and analog paths; must be low-inductance connection. |
| 11 (VCC) | Power Supply | 2.5V or 3.3V ±10% supply; powers logic control and switch transistors; decoupling required. |
| 12 (EN) | Global Enable | Active LOW; disables all outputs to high-impedance state regardless of S pin state. |
| 13 (S) | Channel Select | Single-bit control selecting IAx (S = LOW) or IBx (S = HIGH) for all three channels simultaneously. |
| 14–16 (N.C.) | No Internal Connection | Unbonded pads; no electrical function; must remain unconnected per datasheet note. |
Key Features
| Feature | Design Value |
|---|---|
| Near-zero propagation delay | 0.3 ns typical adds no measurable timing budget penalty in high-speed synchronous bus switching. |
| Beyond Rail-to-Rail switching | Supports input voltages up to 6.0 V with 2.5V/3.3V supply-eliminates need for external level translators. |
| Hot insertion capability | Withstands 10+ V backplane transients for ≤20 ns at ≤120 mA-enables use in live-pluggable telecom modules. |
| Tri-state outputs with independent control | EN pin globally disables all Yx outputs to high-Z, preventing bus contention during system reset or reconfiguration. |
| Low on-resistance variation | RON flatness <2 Ω across 0–3.6 V input range ensures consistent signal attenuation across full logic swing. |
Applications
| PCIe Gen1 Switching | HDMI 1.4 DDC Routing |
|---|---|
|
Use Scenario: Dynamic lane allocation in embedded PCIe root complexes with shared physical connectors. IC Role / Device Role / Timing Role: Bidirectional 2:1 mux for REFCLK and PERST# lines, enabling hardware-reconfigurable link topology.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-bandwidth analog/digital multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB30E | Single-channel, 500 MHz, 3.3V-only supply, 6 Ω RON, no 5V I/O tolerance | Limited to single-path routing; requires external level shifting for mixed-voltage systems | Choose for cost-sensitive single-channel designs where 5V tolerance is unnecessary |
| SN74CBT3244PWR | Octal FET bus switch, 2.5V/3.3V, 5 Ω RON, no enable pin per channel, 300 MHz bandwidth | Fixed 1:1 topology; lacks select logic-requires external gating for 2:1 operation | Prefer when simultaneous 8-bit bus switching is needed and channel selection is handled externally |
Compared with TS3USB30E and SN74CBT3244PWR, PI3CH360LE uniquely integrates 3-channel 2:1 mux functionality with global enable, 5V-tolerant I/O, and hot-insertion hardening-making it optimal for compact, multi-source signal routing in telecom and test infrastructure.

FAQ
Can PI3CH360LE operate with 1.8V supply?
No. The device is specified only for 2.5V ±10% and 3.3V ±10% supply operation. At 1.8V, internal logic thresholds are not met, resulting in undefined enable/select behavior and degraded RON performance. Datasheet absolute minimum VCC is 2.3V for 2.5V mode and 3.0V for 3.3V mode.
Is the thermal pad on PI3CH360LE (TSSOP) electrically connected?
No. The PI3CH360LE TSSOP package does not include an exposed thermal pad. Unlike the ZH (TQFN) variant, the L-suffix TSSOP has no thermal pad-its thermal dissipation relies solely on leads and PCB copper area. Per PS8727A mechanical drawings, pin count remains 16 with no auxiliary thermal terminal.
What is the maximum capacitive load the PI3CH360LE can drive reliably?
The device is characterized up to 10 pF load capacitance in dynamic testing, with bandwidth and propagation delay specifications guaranteed under that condition. Driving >15 pF may reduce –3dB bandwidth below 200 MHz and increase rise/fall times; layout-dependent parasitics should be minimized using short traces and ground return vias.
Does PI3CH360LE support partial power-down (e.g., VCC off while I/O active)?
No. The datasheet specifies that VCC must be applied before any input/output signals. Applying signals with VCC = 0V violates absolute maximum ratings (–0.5 V to +4.6 V supply range), risks latch-up (>250 mA per JESD17), and may cause permanent damage due to uncontrolled internal biasing of ESD protection diodes.
