Product details

Overview

PI5V331QE from Pericom Semiconductor is a true bidirectional dual 4-channel analog multiplexer/demultiplexer designed for S-Video and composite video signal routing. It features 3Ω typical on-resistance, 150 MHz –3dB bandwidth, –58 dB crosstalk at 10 MHz, 10 ns fast switching, and 100 mA output current capability. It operates from a single +5.0 V supply and supports video source selection in broadcast monitors and set-top boxes.

For engineers reviewing the PI5V331QE datasheet, PI5V331QE pinout, PI5V331QE application, or PI5V331QE equivalent, key selection criteria include analog bandwidth, on-resistance matching across channels, crosstalk performance at baseband video frequencies, and compatibility with TTL/CMOS control logic driving RAMDAC outputs.

Technical Context

The PI5V331QE implements two independent 4:1 analog mux/demux paths (A and B), each controlled by a 2-bit binary decoder (IN1/IN0) and enabled via separate ENA/ENB pins. Its switch architecture uses low-threshold MOSFETs optimized for 0–2.0 V analog signal swing under 5 V supply.

Signal integrity is maintained through matched R_ON (3–7 Ω), low channel capacitance (C_ON = 20 pF), and high off-isolation (–38 dB at 10 MHz). The device does not require level-shifting for TTL-compatible control inputs and draws only 0.1 μA quiescent current.

Key Specifications

Parameter	Value and Actual Design Meaning
Bandwidth (–3dB)	150 MHz - supports full NTSC/PAL luminance and chrominance passband without attenuation
On-resistance (R_ON)	3 Ω typical - minimizes voltage drop and gain error in 75 Ω video lines
Crosstalk	–58 dB at 10 MHz - prevents visible ghosting between active and inactive video channels
Switching time (t_ON/t_OFF)	5 ns / 5 ns - enables frame-synchronized source switching without line tearing
Analog signal range	0 to 2.0 V - matches standard composite/S-video peak white levels
Supply voltage	+5.0 V ±5% - compatible with legacy video system power rails
Quiescent current	0.1 μA typical - enables always-on video routing in low-power standby modes

Pinout & Package

The PI5V331QE is housed in a Pb-free, green 16-pin QSOP (150-mil wide) package with 0.025" lead pitch and JEDEC MO-137B-compliant mechanical dimensions.

Pin/Terminal	Circuit Role	Design Meaning
ENA, ENB	Channel enable inputs	Active-high enables for A-path and B-path independently; allows partial channel shutdown
IN1, IN0	2-bit address inputs	Selects one of four analog I/O pairs per path (S1–S4 → DA/DB); TTL/CMOS compatible
S1A–S4A, S1B–S4B	Analog I/O terminals	Bidirectional ports for video sources; internally routed to DA/DB when selected and enabled
DA, DB	Analog outputs/inputs	Common video bus nodes shared across both paths; support bidirectional signal flow
VCC, GND	Power supply	Single 5 V rail powers all analog and digital circuitry; no separate analog/digital supplies required

Key Features

Feature	Design Value
True bidirectional operation	Supports signal flow from Sx to D or D to Sx without polarity inversion or DC blocking
Matched 3 Ω on-resistance	Ensures ≤0.1% gain mismatch across all eight switched paths, critical for color fidelity
–58 dB crosstalk @ 10 MHz	Prevents interference between adjacent video sources during simultaneous multi-input monitoring
100 mA output current rating	Drives multiple 75 Ω video loads in parallel without external buffers
Ultra-low 0.1 μA quiescent current	Reduces system-level standby power in always-on video gateways and matrix switchers

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual 4-channel analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
QS4A210	Functionally identical pinout and electrical specs; same manufacturer, older part number	No difference - direct second-source replacement with identical qualification data	Select QS4A210 only if legacy BOM compliance or long-term availability assurance is required
ADG732BRUZ	32-channel single-supply CMOS mux; 4 Ω R_ON, 125 MHz BW, but requires 3.3 V supply and different control interface	Not suitable for direct 5 V video systems; lacks dual-path independent enable control	Consider only for new 3.3 V designs where channel count >8 justifies higher integration density

Compared with QS4A210, PI5V331QE offers identical functionality with updated green packaging; versus ADG732BRUZ, it provides native 5 V operation, lower R_ON, and dedicated dual-path enable architecture essential for video routing.

Manufacturer

Pericom Semiconductor was a fabless analog IC designer specializing in high-speed signal integrity solutions for video, timing, and interface applications before its acquisition by Diodes Incorporated in 2016.

The PI5V331QE belongs to Pericom's wideband analog switch product line, engineered specifically for broadcast-quality video routing where low R_ON, high bandwidth, and crosstalk immunity are mandatory.

FAQ

Is PI5V331QE compatible with 3.3 V logic control signals?

Yes. The PI5V331QE accepts TTL/CMOS logic levels: VIH is guaranteed ≥2.0 V, and VIL is ≤0.8 V, making it fully compatible with 3.3 V microcontrollers and FPGA I/Os driving ENA/ENB/IN1/IN0. No level-shifter is needed.

Can PI5V331QE handle 2 V_PP composite video signals without distortion?

Yes. Its specified analog signal range is 0 to 2.0 V, and dynamic tests confirm <0.64% differential gain and <0.27° differential phase error at 3.58 MHz - well within NTSC/PAL broadcast tolerances for baseband video.

What is the maximum capacitive load the PI5V331QE can drive directly?

The device is characterized with 75 Ω termination and 20 pF load in switching time tests. While not rated for heavy capacitive loads, it reliably drives standard 75 Ω coaxial cables (typically ≤50 pF/m) up to 3 m without equalization, given its 150 MHz bandwidth and 100 mA output capability.

Does PI5V331QE support hot insertion or live signal switching?

Yes. Its bidirectional architecture, rail-to-rail analog range, and absence of body diode conduction paths allow safe hot switching of live video signals. However, ensure ENA/ENB are held low during power-up to prevent undefined channel states.
