1 19-71; Rev ; 1/.5Ω/7Ω Quad SPST Switches with Over-Rail General Description The MAX851/MAX851H/MAX85/MAX85H family of quad single-pole/single-throw (SPST) switches operates from a single +2V to +5.5V supply and can handle signals greater than the supply rail. These switches feature low.5ω on-resistance with pf on-capacitance or 7Ω on-resistance with pf on-capacitance, making them ideal for switching audio and data signals. The MAX851/MAX851H are configured with four SPST switches and feature a comparator for headphone detection or mute/send key functions. The MAX85/MAX85H have four SPST switches but do not include a comparator. For over-rail applications, these devices offer either the pass-through or high-impedance option. For the MAX851/ MAX85, signals greater than the positive supply (up to 5.5V) pass through the switch without distortion. For the MAX851H/MAX85H, the switch input becomes high impedance when the input signal exceeds the supply rail. The MAX851/MAX851H/MAX85/MAX85H are available in the space-saving, 1-pin, mm x mm thin QFN package and operate over the - C to +85 C extended temperature range.

9 MAX851 MAX851H PIN MAX85 MAX85H NAME Detailed Description The MAX851/MAX851H/MAX85/MAX85H are low on-resistance, low-voltage, analog switches that operate from a +2V to +5.5V single supply and are fully specified for nominal.v applications. The MAX851/MAX85 devices feature over-rail signal capability that allows signals up to 5.5V with supply voltages down to 2.V to pass through without distortion. The MAX851H/ MAX85H enter high-impedance mode when the signal voltage exceeds and return to normal operation when the signal voltage drops below.

They are designed to switch D+ and D- USB signals with a guaranteed skew of less than 1ns (see Figure 2), as measured from 5% of the input signal to 5% of the output signal. The MAX851_ features a comparator that can be used for headphone or mute detection. The comparator threshold is internally generated to be approximately 1/ of. MAX851/MAX851H/MAX85/MAX85H 9

12 MAX851/MAX851H/MAX85/MAX85H Applications Information Digital Control Inputs The logic inputs (IN_) accept up to +5.5V even if the supply voltages are below this level. For example, with a +.V supply, IN_ can be driven low to GND and high to +5.5V, allowing for mixing of logic levels in a system. Driving IN_ rail-to-rail minimizes power consumption. For a +2V supply voltage, the logic thresholds are.5v (low) and 1.V (high). For a +5V supply voltage, the logic thresholds are.8v (low) and 1.8V (high). Analog Signal Levels The on-resistance of these switches changes very little for analog input signals across the entire supply voltage range (see Typical Operating Characteristics). The switches are bidirectional; therefore, NO_ and COM_ can be either inputs or outputs. Comparator The positive terminal of the comparator is internally set to /. When the negative comparator terminal (CIN) is below the threshold ( / ), the comparator output (COUT) goes high. When CIN rises above /, COUT goes low. The comparator threshold allows for detection of headphones since headphone audio signals are typically biased to / 2.
