Launch: MS4561 Dual/Quad-Channel Bidirectional Level Translator

In electronic systems with mixed-voltage designs, signal level mismatch is a common design challenge—for example, when a 3.3V microcontroller needs to communicate with a 5V sensor, or when a 1.8V digital circuit must interface with a 3.3V analog circuit. Traditional level-shifting solutions often face speed bottlenecks and design complexity issues.

RuiMeng Technology’s MS4561 automatic bidirectional level translator offers a superior solution. This series provides dual-channel and quad-channel configurations, supporting a wide voltage range of 1.65V to 5.5V for Port A and 2.3V to 5.5V for Port B (VCCA ≤ VCCB), making it fully compatible with 1.8V, 2.5V, 3.3V, and 5V logic systems.
