Product details
Overview
PI3CH360QE 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 features 5Ω on-resistance, 500 MHz –3dB bandwidth, near-zero propagation delay (0.3 ns), 3.3V/2.5V dual-supply operation, and rail-to-rail switching capability up to 5V I/O tolerance.
For engineers reviewing the PI3CH360QE datasheet, PI3CH360QE pinout, PI3CH360QE application, or PI3CH360QE equivalent, key selection criteria include its sub-1ns enable/disable timing (1.5–9.0 ns), –60 dB crosstalk and off-isolation, hot-insertion capability, and industrial temperature range (–40°C to +85°C) for reliable signal integrity in dense PCB layouts.
Technical Context
The PI3CH360QE 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).
Its CMOS NanoSwitch™ architecture supports simultaneous 2.5V and 3.3V supply operation while maintaining 5V-tolerant I/O pins - enabling interoperability between mixed-voltage domains without level shifters. ESD protection (2 kV HBM) and latch-up immunity (>250 mA per JESD17) ensure robustness in telecom and datacom backplane environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3dB) | 500 MHz - supports HDMI 1.4, USB 2.0, and PCIe Gen1 signal routing without attenuation |
| RON (On-Resistance) | 4–8 Ω - minimizes insertion loss and voltage drop across switched paths at DC and low frequencies |
| tPLH / tPHL | 0.3 ns - negligible propagation delay enables timing-critical signal path bridging |
| tPZH / tPHZ | 1.5–9.0 ns - fast enable/disable allows dynamic reconfiguration in real-time switching applications |
| OIRR / XTALK | –60 dB - ensures channel isolation for multi-lane parallel buses and differential pair routing |
| VIO Tolerance | –0.5 V to +6.0 V - permits direct interfacing with 5V logic or overvoltage-safe hot-swap operation |
| Supply Range | 2.5 V ±10% or 3.3 V ±10% - supports dual-voltage system integration without external regulators |
Pinout & Package
PI3CH360QE is packaged in a Pb-free, RoHS-compliant 16-pin QSOP (150-mil width, 1.27 mm pitch), with 1.75 mm body height and 0.203 mm lead thickness. Pin 1 marked via notch; pin 16 is VCC, pin 8 is GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IA0–IC0 | Input A for Channels 0–2 | First input source per channel; accepts 5V-tolerant logic or analog signals |
| IA1–IC1 | Input B for Channels 0–2 | Second selectable input per channel; identical electrical specs to IAx pins |
| YA–YC | Output for Channels 0–2 | Bidirectional, 3-state outputs; high-impedance when EN = HIGH or S invalid |
| S | Channel Select | Logic-controlled mux selection: S = LOW → IAx routed; S = HIGH → IBx routed |
| EN | Global Enable | Active-LOW enable: EN = LOW activates all channels; EN = HIGH forces all Yx to Hi-Z |
| VCC | Power Supply | 2.5V or 3.3V supply input; powers internal logic and switch transistors |
| GND | Ground Reference | Common return path for supply and signal references; critical for noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| Near-zero propagation delay | 0.3 ns typical - preserves signal edge integrity in high-speed serial links |
| 5Ω low on-resistance | Ensures <1% voltage drop at 100 mA load - maintains signal amplitude across switched paths |
| 500 MHz bandwidth | Supports full-rate switching of DDR2/DDR3 address/control lines and LVDS video streams |
| Rail-to-rail switching | Accepts input voltages beyond VCC/GND rails (–0.5 V to +6.0 V) - eliminates need for external clamping |
| Hot-insertion capable | Withstands 10+ V backplane transients for ≤20 ns at ≤120 mA - suitable for modular telecom line cards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiplexer/demultiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB30E | Single-channel, 3.3V-only supply, 6Ω RON, 500 MHz BW, integrated ESD diodes | Limited to USB 2.0 signal switching; lacks 3-channel parallel routing | Prefer for cost-sensitive single-lane USB applications where 3-channel consolidation is unnecessary |
| SN74CBT3245APW | Octal FET bus switch, 5V supply only, 7Ω RON, 200 MHz BW, no enable pin per channel | Higher supply voltage requirement and lower bandwidth limit performance in high-speed mixed-signal designs | Select only when legacy 5V systems require octal-level switching and bandwidth <200 MHz suffices |
Compared with TS3USB30E and SN74CBT3245APW, PI3CH360QE uniquely delivers triple-channel, dual-supply (2.5V/3.3V), 500 MHz routing with per-channel 3-state control - making it optimal for space-constrained, multi-lane signal consolidation where timing, voltage flexibility, and channel density are jointly critical.

FAQ
What is the maximum allowable input voltage on IA0–IC1 pins when VCC = 2.5V?
The PI3CH360QE supports –0.5 V to +6.0 V DC input voltage on all I/O pins regardless of VCC level. With VCC = 2.5 V, inputs may safely swing from –0.5 V to +6.0 V, enabling rail-to-rail switching and compatibility with 5V logic families without level shifters or clamping circuits.
Does PI3CH360QE support hot-plug insertion in backplane applications?
Yes - the device withstands transient overvoltages up to 10+ V for ≤20 ns at ≤120 mA per pin, meeting hot-insertion requirements for telecom line cards and modular servers. Its 2 kV HBM ESD rating and >250 mA latch-up immunity further enhance reliability during live board insertion.
How does the enable (EN) pin interact with the select (S) pin in controlling channel states?
EN is active-low and overrides S: when EN = HIGH, all outputs (YA–YC) enter high-impedance state regardless of S value. When EN = LOW, S determines routing - S = LOW connects IAx to Yx; S = HIGH connects IBx to Yx. This hierarchical control enables global disable for power gating or fault isolation.
Can PI3CH360QE be used to route differential signals like LVDS or HDMI TMDS?
Yes - its matched 5Ω RON, 10 pF CON, and <0.3 ns propagation delay preserve differential pair skew and amplitude. For HDMI TMDS, use adjacent IA/IB pins per lane and maintain tight layout symmetry; measured –60 dB crosstalk ensures minimal inter-pair interference at 2.25 Gbps.
