# LMH6574MAX/NOPB (Component) ## Description Video Switch IC 1 Channel 14-SOIC The LMH6574MAX/NOPB is a high-speed, 4:1 video multiplexer amplifier manufactured by Texas Instruments. It is designed for routing multiple analog video or high-bandwidth signals into a single output while maintaining excellent signal integrity. With wide bandwidth, low distortion, and fast switching characteristics, it is well-suited for applications such as video switching, RGB routing, medical imaging, and high-speed data acquisition systems. Key Features 4:1 high-speed analog video multiplexer Wide small-signal bandwidth: ~500 MHz (typical) Fast channel switching time: ~8 ns (typical) Low differential gain and phase for video fidelity High slew rate: ~1800 V/µs Low crosstalk and channel-to-channel isolation Single-supply operation: 5 V TTL/CMOS compatible logic inputs Internal 75 Ω back-termination support (video applications) Output disable (high impedance mode) Electrical Characteristics Supply Voltage (Vcc): 4.5 V to 5.5 V Supply Current: ~13 mA (typical) Input Voltage Range: 0 V to Vcc Output Voltage Swing: ~2 Vpp (video typical) Gain: 2 V/V (fixed gain configuration) Input Resistance: High impedance Output Resistance: Low impedance (video drive capable) Dynamic Performance -3 dB Bandwidth: ~500 MHz Slew Rate: ~1800 V/µs Settling Time: ~10 ns Channel Switching Time: ~8 ns Crosstalk: <-60 dB (typical at 10 MHz) Package Information Package Type: SOIC-8 (MAX) Mounting Type: Surface Mount Lead Finish: NiPdAu (RoHS compliant) Operating Temperature Range: -40°C to +85°C Pin Configuration (Summary) 4 Analog Inputs (IN0–IN3) 1 Analog Output (OUT) 2 Digital Select Lines (A0, A1) Enable/Disable Control (EN) Power Supply (Vcc) Ground (GND) Applications Video signal routing and switching (RGB, CVBS) CCTV and broadcast systems Medical imaging equipment Test and measurement instruments High-speed analog multiplexing Data acquisition front-end switching Compliance & Notes RoHS compliant (NOPB = Lead-free package) Designed for 75 Ω video systems Requires proper PCB layout for high-frequency performance (controlled impedance, short traces) #commonpartslibrary #integratedcircuit ## Component Details - **Owner:** adrian95 - **Created:** 4/22/2026 - **Last Updated:** 4/22/2026 - **Visibility:** Public - **Datasheet URL:** http://www.ti.com/lit/gpn/LMH6574 - **Manufacturer Part Number:** LMH6574MAX/NOPB - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Name:** Texas Instruments - **Part Type:** Integrated Circuit - **Part Type:** Integrated Circuits - **Sub-Type:** Logic - **Manufacturer:** Texas Instruments - **MPN:** LMH6574MAX/NOPB - **Mount Type:** Surface Mount - **Package / Case Code:** 14-SOIC - **Pin Count:** 14 - **Logic Function:** AND - **Compliance:** Rohs, NiPdAu, Lead Free ## Pins | Pin | Name | Type | |-----|------|------| | 1 | IN0 | | | 2 | GND_1 | | | 3 | IN1 | | | 4 | GND_2 | | | 5 | IN2 | | | 6 | V- | | | 7 | IN3 | | | 8 | A0 | | | 9 | A1 | | | 10 | ~EN | | | 11 | SD | | | 12 | FB | | | 13 | OUT | | | 14 | V+ | | --- *Generated from [https://www.flux.ai/adrian95/lmh6574maxnopb](https://www.flux.ai/adrian95/lmh6574maxnopb)*
