Diodes Incorporated PI5V330SWEX

Overview

PI5V330SWEX from Pericom Semiconductor is a quad 2-channel analog multiplexer/demultiplexer optimized for RGB and composite video signal routing. It features 570 MHz bandwidth, 5 Ω typical on-resistance, –80 dB crosstalk at 10 MHz, 10 ns switching time, and operates from a single +5.0 V supply-enabling high-fidelity video source selection in graphics cards and AV receivers.

For engineers reviewing the PI5V330SWEX datasheet, PI5V330SWEX pinout, PI5V330SWEX application, or PI5V330SWEX equivalent, key selection criteria include analog bandwidth, on-resistance matching across channels, enable-controlled bidirectional switching, and SOIC-16 packaging compatibility with legacy video interface layouts.

Technical Context

The PI5V330SWEX implements four independent 2:1 analog switches controlled by a shared digital select (IN) and global enable (EN) input. Each switch supports true bidirectional signal flow with no polarity restriction on analog I/O pins (S1A–S1D, S2A–S2D, DA–DD).

Its internal decoder drives low-capacitance transmission gates with matched R_ON (5 Ω typ.) and minimal charge injection (<1 pC), preserving video signal integrity up to 570 MHz while maintaining –48 dB off-isolation and –80 dB non-adjacent crosstalk at 10 MHz.

Supply support for PI5V330SWEX includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Pericom Semiconductor was a fabless analog IC designer specializing in high-speed signal integrity solutions for computing, communications, and consumer electronics before its acquisition by Diodes Incorporated in 2016.

The PI5V330S product line targets analog video interface applications-specifically addressing the need for low-distortion, high-bandwidth switching in legacy and transitional video systems using RGB, YPbPr, or composite standards.

FAQ

What is the maximum analog signal voltage range supported by the PI5V330SWEX?

The PI5V330SWEX supports an analog signal range of 0 V to 2.0 V when operating at VDD = 5.0 V. This is specified under DC Electrical Characteristics as VANALOG. Signals exceeding 2.0 V may forward-bias internal ESD clamps or degrade linearity. The device is not rated for rail-to-rail analog swing and must be used within this defined range for guaranteed performance.

Can the PI5V330SWEX be used with 3.3 V logic control signals?

Yes-the PI5V330SWEX accepts 3.3 V logic levels on EN and IN inputs. Its VIH (input HIGH voltage) minimum is 2.0 V, and VIL (input LOW voltage) maximum is 0.8 V, making it fully compatible with standard 3.3 V CMOS/TTL logic driving the control pins while powered from +5.0 V.

Does the PI5V330SWEX support bidirectional signal flow on all analog pins?

Yes-S1A–S1D, S2A–S2D, and DA–DD pins are fully bidirectional. Signal direction depends solely on external biasing: any pin can serve as input or output. This enables flexible use as a mux (S1/S2 → D) or demux (D → S1/S2) without hardware reconfiguration.

Is there a recommended PCB layout practice to maintain 570 MHz bandwidth?

To preserve 570 MHz bandwidth, minimize trace length and impedance discontinuities on all analog paths (S1x, S2x, Dx). Use controlled-impedance 75 Ω routing where possible, place 0.1 µF ceramic decoupling capacitors within 2 mm of VDD/GND pins, and avoid vias or stubs on high-speed analog nets. Ground plane integrity beneath the SOIC-16 footprint is critical for return path continuity.
