Product details
Overview
STMAV340TTR from STMicroelectronics is a quad SPDT analog video switch IC designed for RGB and composite-video signal routing in high-fidelity display systems. It delivers 300MHz bandwidth, 4Ω typical ON-resistance, <7Ω max RON, –58dB crosstalk at 10MHz, and guaranteed break-before-make timing across all four channels. Used in LCD monitors and advanced TVs to route video signals without degradation.
For engineers reviewing the STMAV340TTR datasheet, STMAV340TTR pinout, STMAV340TTR application, or STMAV340TTR equivalent, key selection criteria include its low RON matching (±0.5Ω channel-to-channel), 7pF A-port I/O capacitance, TTL-compatible control inputs (VIH = 2.0V min), –40°C to +85°C operation, and TSSOP16 package compatibility with high-density PCB layouts.
Technical Context
The STMAV340TTR implements four independent bi-directional SPDT analog switches controlled by a shared OE_N enable and S select input. Each channel routes one A-port signal to either B or C output under break-before-make timing, eliminating signal shorting during switching.
Its CMOS architecture achieves low propagation delay (<5.7ns enable/disable) and minimal ground bounce via zero-bounce flow-through mode. Differential gain (0.64%) and phase (0.1°) are optimized for NTSC/PAL video fidelity, while 12pF ON-capacitance and 7pF/5pF I/O capacitance preserve high-frequency signal integrity up to 300MHz.
Key Specifications

| 1A, 2A, 3A, 4A | Input/Output Port A | Common analog video I/O pins shared across all four SPDT switches |
| OE_N | Active-Low Enable | Drives all switches into high-impedance state when HIGH; enables switching when LOW |
| S | Select Input | Chooses B (S = 0) or C (S = 1) output path for all four channels simultaneously |
| VCC, GND | Power Supply | Single 4.0–5.5V supply with dedicated ground; no separate analog/digital rails required |
Key Features

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 | Higher RON (9Ω typ.), lower bandwidth (200MHz), no integrated clamp diodes | Limited to lower-resolution CVBS; requires external ESD protection | Lower cost where video fidelity and robustness are secondary |
| ADG5412BRUZ | Higher supply range (±5V to ±22V), 12Ω RON, not TTL-compatible, no video-optimized specs | Designed for general-purpose instrumentation, not video signal integrity | Only suitable if bipolar supplies and higher voltage tolerance are required |
Compared with TS3V330DBQR and ADG5412BRUZ, the STMAV340TTR uniquely combines 300MHz bandwidth, sub-7Ω RON, video-grade differential gain/phase, and integrated undershoot clamps-making it the only option qualified for RGB and composite video in consumer display equipment.

FAQ
What is the maximum video resolution supported by the STMAV340TTR?
The STMAV340TTR supports up to 1080i resolution via RGB or YPbPr component video. Its 300MHz bandwidth and 0.64% differential gain meet SMPTE RP-149 requirements for HD video signal integrity, enabling clean transmission of 720p/1080i timing without added jitter or amplitude distortion.
Does the STMAV340TTR require external pull-up resistors on control pins?
No external pull-ups are required on OE_N or S inputs. The device accepts TTL-level logic directly: VIH ≥ 2.0V and VIL ≤ 0.8V over the full 4.0–5.5V VCC range. However, unused control inputs must be tied HIGH or LOW-floating states are prohibited per datasheet Section 5.
Can the STMAV340TTR be used for audio signal switching?
While functional for line-level analog audio, the STMAV340TTR is not optimized for audio applications. Its 300MHz bandwidth and video-specific parameters (e.g., differential gain/phase) exceed audio needs, and its 4Ω RON introduces negligible THD-but dedicated audio switches like TS5A23157 offer better channel separation and lower noise floor for critical audio paths.
Is the TSSOP16 package of STMAV340TTR RoHS and REACH compliant?
Yes. The STMAV340TTR uses STMicroelectronics' ECOPACK®-qualified TSSOP16 package, which is lead-free, RoHS-compliant (2011/65/EU), and REACH-conformant (SVHC-free per latest declaration). Full compliance documentation is available through ST's quality portal under document number ECOPACK-001.
