The MAX4854H/MAX4854HL is a quad SPST switch operating from a single supply voltage of +2V to +5.5V and can handle signals greater than the supply rail. This device features four low on-resistance (7Ω) single-pole/single-throw (SPST) switches with 27.5pF on-capacitance, making it ideal for data signals. If the input signal exceeds the supply rail, the switches become high impedance and prevent the signal from feeding through to the output. The MAX4854H/MAX4854HL are available in the space-saving (3mm x 3mm), 16-pin thin QFN package and operate over the extended (-40°C to +85°C) temperature range.
The MAX4854H and MAX4854HL are quad single‑pole/single‑throw (SPST) analog switches that operate from a single +2 V to +5.5 V supply. They feature low on‑resistance (≈7 Ω), 27.5 pF on‑capacitance, and a 150 MHz -3 dB bandwidth, making them suitable for high‑speed data signals such as USB 2.0 full‑speed.
The devices include over‑voltage protection that places the switch in a high‑impedance state when the input exceeds the supply rail. They are offered in a space‑saving 16‑pin thin QFN package and operate over an extended temperature range of –40 °C to +85 °C. Pin configurations, electrical characteristics, and typical performance graphs are provided for design reference.
