• Manufacturer Part Number: MAX4851H
• Description: The MAX4851/MAX4851H/MAX4853/MAX4853H family of quad single-pole/single-throw (SPST) switches operates from a single +2V to +5
• Manufacturer: Maxim

The MAX4851/MAX4851H/MAX4853/MAX4853H are low
on-resistance, low-voltage, analog switches that operate
from a +2V to +5.5V single supply and are fully specified
for nominal 3.0V applications. The MAX4851/MAX4853
devices feature over-rail signal capability that allows sig-
nals up to 5.5V with supply voltages down to 2.0V to
pass through without distortion. The MAX4851H/
MAX4853H enter high-impedance mode when the signal
voltage exceeds V
when the signal voltage drops below V

These quad SPST switches have low on-channel capaci-
tance, which allows switching of the data signals for USB
2.0/1.1 applications (12Mbps). They are designed to
switch D+ and D- USB signals with a guaranteed skew
of less than 1ns (see Figure 2), as measured from 50%
of the input signal to 50% of the output signal.
The MAX4851_ features a comparator that can be used
for headphone or mute detection. The comparator
threshold is internally generated to be approximately
1/3 of V
