MAX4854H/MAX4854HL 19-3376 Rev 1 1/05 Quad SPST, High-Bandwidth, Signal Line Protection Switch General Description Features The MAX4854H/MAX4854HL analog switches operate USB 2.0 Full Speed (12MB) and USB 1.1 Signal from a single +2V to +5.5V supply and can handle sig- Switching nals greater than the supply rail. These devices feature Overvoltage Protection if Signal Exceeds V CC four low on-resistance (7 ) single-pole/single-throw (SPST) switches, with 27.5pF on-capacitance, making 150MHz -3dB Bandwidth them ideal for data signals. If the input signal exceeds the 27.5pF On-Capacitance supply rail, the switches become high impedance and prevent the signal from feeding through to the output. +2V to +5.5V Supply Range The MAX4854H/MAX4854HL are available in the 7 On-Resistance space-saving (3mm x 3mm), 16-pin, thin QFN package and operate over the extended (-40C to +85C) tem- Low 10A Supply Current perature range. 1.8V Logic Compatible Available in a Space-Saving (3mm x 3mm) Applications 16-Pin TQFN Package USB Switching Ordering Information High-Bandwidth Data Switching Cellular Phones PIN- TOP PART TEMP RANGE PACKAGE MARK Notebook Computers MAX4854HETE -40C to +85C 16 TQFN-EP* ACD PDAs and Other Handheld Devices MAX4854HLETE -40C to +85C 16 TQFN-EP* ACX *EP = Exposed paddle.

Signals on IN exceeding GND are clamped by an internal diode. Limit the forward-diode current to the maximum current rating. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ELECTRICAL CHARACTERISTICS (V = +2.7V to +5.5V, T = -40C to +85C, unless otherwise noted.
