MAX4854 is a 4-way single-pole/single-throw switch that is powered by a single supply of +2V to +5.5V and can handle signals that are greater than the supply swing. The switch has a low on-resistance and low on-capacitance, making it ideal for data signal switching. For over-range applications, signals that are greater than the positive supply (up to +5.5V) can still pass through the switch without distortion. MAX4854 is housed in a space-saving, 16-pin, 3mm x 3mm thin QFN package and operates in an extended temperature range of -40°C to +85°C.
The MAX4854 is a four‑channel, single‑pole‑single‑throw (SPST) analog switch designed for USB 2.0/1.1 data‑line switching and other high‑speed signal applications. It operates from a single supply of +2 V to +5.5 V and can pass signals that exceed the supply voltage without distortion, making it suitable for handheld devices such as phones, laptops, and PDAs.
The device is offered in a compact 16‑pin thin QFN package (3 mm × 3 mm) and features a typical on‑resistance of 7 Ω, on‑capacitance of 30 pF, off‑capacitance of 13 pF, a –3 dB bandwidth of 150 MHz, and fast turn‑on/turn‑off times (≈100 ns / 60 ns). Electrical characteristics, pin functions, and typical performance graphs are provided in the datasheet. This manual is written in Chinese.
