Product details

Overview

STMAV335TTR from STMicroelectronics is a bi-directional triple SP3T analog video switch optimized for RGB and YPbPr component video routing in consumer displays. It delivers 300 MHz bandwidth, 3 Ω typical ON-resistance (at V_IN = 1.0 V, I_ON = 13 mA), <7 pF I/O capacitance, –60 dB OFF-isolation at 10 MHz, and operates from 4.0–5.5 V over –40°C to +85°C - enabling high-fidelity signal switching in LCD TVs and front projectors.

For engineers reviewing the STMAV335TTR datasheet, STMAV335TTR pinout, STMAV335TTR application, or STMAV335TTR equivalent, key selection criteria include channel-to-channel R_ON matching (<±0.5 Ω), propagation delay (<5.7 ns enable/disable), differential gain (0.64%), and TSSOP16 footprint compatibility with legacy video routing designs.

Technical Context

The STMAV335TTR implements a CMOS-based 3×3 analog switch matrix controlled by dual TTL-compatible SEL1/SEL2 inputs, selecting among three independent video paths: YPbPr1, YPbPr2, or RGB. Its flow-through architecture ensures zero bounce during switching transitions and eliminates ground noise coupling between channels.

Designed for minimal signal degradation, it achieves low crosstalk (–58 dB at 10 MHz) and high channel-to-channel isolation via matched R_ON, symmetric layout, and integrated undershoot clamp diodes on all data and control pins - critical for maintaining NTSC/PAL timing integrity and color fidelity in multi-source display systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Bandwidth (–3 dB)	300 MHz - supports full HD (1080p) analog video signals without attenuation
ON Resistance (R_ON)	3 Ω typ. at 1.0 V - minimizes voltage drop and DC offset in RGB/YPbPr paths
R_ON Matching	≤0.5 Ω max. between channels - preserves color balance and luminance uniformity
I/O Capacitance	7 pF (Y/R, Pb/G, Pr/B) - reduces high-frequency loading and edge distortion
OFF-Isolation	–60 dB at 10 MHz - suppresses leakage from active to inactive video channels
Differential Gain/Phase	0.64% / 0.1° - meets broadcast-grade video fidelity requirements for consumer displays
ESD Rating (HBM)	>2 kV - protects against handling damage during PCB assembly and system integration

Pinout & Package

TSSOP16 package (4.9 × 6.4 mm, 0.65 mm pitch), lead-free ECOPACK® compliant, with exposed pad not electrically connected.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6, 7, 10, 11, 12, 13, 14, 15, 16	Analog I/O (Y1, Pb1, Pr1, Y2, Pb2, Pr2, R, G, B, Y/R, Pb/G, Pr/B)	Bidirectional video signal paths; each pair forms one SP3T channel with matched R_ON and C_I/O
8, 9	Control Inputs (SEL1, SEL2)	TTL-compatible select lines determining active channel (YPbPr1/YPbPr2/RGB); tied high via pull-up when unused
16	VCC	4.0–5.5 V supply; must be powered before applying video or control signals
8	GND	Signal and power reference plane; decoupling capacitor required near pin

Key Features

Feature	Design Value
Zero-bounce flow-through mode	Eliminates mechanical contact artifacts and ground bounce noise during channel switching
Undershoot clamp diodes	Integrated protection on all I/O and control pins prevents negative voltage excursions below –1.2 V
Low quiescent current	3 µA typical ICC - enables always-on video routing in standby-capable consumer electronics
Channel-to-channel skew	<100 ps - maintains RGB/Y-Pb-Pr timing alignment for artifact-free image rendering
High ESD robustness	>2 kV HBM on all pins - reduces field failure risk in unshielded display interconnects

Applications

Advanced LCD TV

Front Projector

Use Scenario: Switching between HDMI-scaled RGB, composite CVBS, and component YPbPr inputs to single panel driver.

IC Role / Device Role / Timing Role: Analog multiplexer routing baseband video signals with sub-100 ps skew and no DC offset shift.

Use Value: Preserves 1080p/60Hz timing integrity and color accuracy across input sources without external level-shifting or buffering.

Use Scenario: Selecting between two YPbPr sources (Blu-ray player and media server) feeding DMD or LCoS imaging engine.

IC Role / Device Role / Timing Role: High-isolation SP3T switch ensuring >60 dB crosstalk suppression between adjacent video channels.

Use Value: Prevents ghosting and color bleed during source transitions while maintaining differential gain <0.7%.

Notebook PC Docking Station

DVD Player with Multi-Output

Use Scenario: Routing internal GPU RGB output to external VGA or internal LVDS panel while supporting hot-plug detection.

IC Role / Device Role / Timing Role: Bidirectional analog switch enabling simultaneous display mirroring and independent scaling path selection.

Use Value: Enables zero-latency source switching and eliminates need for discrete op-amp buffers in compact form factor.

Use Scenario: Distributing decoded YPbPr output to both main display and secondary zone (e.g., rear-seat monitor).

IC Role / Device Role / Timing Role: 1-to-3 analog splitter using flow-through mode to drive multiple loads without gain loss.

Use Value: Reduces BOM count by replacing three separate amplifiers with single low-R_ON switch and passive termination.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TS3V330DBQR	Lower bandwidth (200 MHz), higher R_ON (6 Ω typ.), no integrated clamp diodes	Suitable only for SD/ED video; requires external ESD protection	Select if cost-sensitive and operating below 720p resolution
ADG774ARUZ	Quad SPDT instead of triple SP3T; 400 MHz bandwidth but 4.5 Ω R_ON; no video-optimized AC specs	Requires external logic for 3-input selection; lacks differential gain/phase characterization	Select only for non-broadcast applications where timing skew is less critical

Compared with TS3V330DBQR and ADG774ARUZ, the STMAV335TTR uniquely combines triple SP3T topology, broadcast-grade video specs (DG/DP, crosstalk), and integrated clamping - making it irreplaceable for multi-format HD display switching where signal fidelity and layout simplicity are co-prioritized.

FAQ

What is the maximum video resolution supported by STMAV335TTR?

The STMAV335TTR supports up to 1080p/60Hz analog video signals, validated by its 300 MHz –3 dB bandwidth and <0.7% differential gain error at 3.58 MHz. Its low R_ON and matched channel characteristics preserve timing margins required for progressive-scan RGBHV and YPbPr interfaces without external equalization.

Can STMAV335TTR operate with 3.3 V logic control signals?

No - STMAV335TTR requires V_CC ≥4.0 V and its SEL1/SEL2 inputs are TTL-compatible with V_IL ≤0.8 V and V_IH ≥2.0 V, but are not 3.3 V tolerant when V_CC = 5 V. Direct connection to 3.3 V logic may cause undefined switching behavior; level translation or pull-up to V_CC is mandatory.

Does STMAV335TTR require external termination resistors?

Yes - for optimal 75 Ω video impedance matching, 75 Ω series resistors should be placed at each analog output (Y1/Y2/R etc.) and 75 Ω parallel termination at the destination load. The device's 7 pF I/O capacitance and low R_ON minimize reflections, but proper termination remains essential for <1080p signal integrity.

Is STMAV335TTR still in production?

STMAV335TTR is marked as obsolete by STMicroelectronics per official documentation, but Aetrix Electronics maintains legacy inventory and offers extended lifecycle support including obsolescence forecasting, cross-reference assistance, and last-time-buy coordination for ongoing production programs.
