Selecting a high-performance signal switch is crucial for portable devices and low-voltage systems. The MSG754, a CMOS quad single-pole single-throw (SPST) switch from Ruimeng Technology, is a key component designed for low-voltage applications. It operates from 1.8V to 5.5V, supports 1.8V logic control, and can interface directly with various low-voltage main control chips.

Featuring a typical on-resistance of 3.3Ω and a high -3dB bandwidth of 120MHz, this device maintains excellent signal transmission efficiency and integrity across its wide voltage range. It is offered in both SOP14 and TSSOP14 packages, providing compact and flexible solutions for portable and battery-powered systems.

Core Advantages

01 Low Power Consumption & High Precision

With a typical on-resistance of just 3.3Ω and excellent flatness, it enables precise signal transmission. Its extremely low off-leakage current of 3nA significantly reduces static power consumption and improves overall system efficiency.

02 Wide Voltage Compatibility & High Flexibility

Supporting a wide operating voltage range from 1.8V to 5.5V and 1.8V logic control, it easily adapts to various low-voltage MCUs or DSPs, simplifying system power design.

03 Excellent High-Frequency Performance

A -3dB bandwidth of 120MHz and channel crosstalk as low as -70dB @ 1MHz effectively ensure high transmission quality and isolation in high-frequency and multi-signal systems.

04 High Reliability Design

With an operating temperature range of -40℃ to +125℃ and an HBM ESD protection level of ±3kV, it meets the requirements for stable operation in harsh industrial and power equipment environments.
