The MAX4854H/MAX4854HL quad SPST switches have
low on-resistance, operate from a +2V to +5.5V supply,
and are fully specified for nominal 3.0V applications.
These devices feature overvoltage protection by
putting the switch into high-impedance mode when the
switch input exceeds V
These switches have low 27.5pF on-channel capaci-
tance, which allows for 12Mbps switching of the data sig-
nals for USB 2.0 full speed/1.1 applications. The
MAX4854H/MAX4854HL 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 logic inputs (IN_) accept up to +5.5V even if the
supply voltages are below this level. For example, with a

high to +5.5V, allowing for mixing of logic levels in a
system. Driving IN_ rail-to-rail minimizes power con-
sumption. For a +2V supply voltage, the logic thresholds
are 0.5V (low) and 1.4V (high); for a +5V supply voltage,
the logic thresholds are 0.8V (low) and 1.8V (high).
The on-resistance of these switches changes very little
for analog input signals across the entire supply volt-
age range (see the Typical Operating Characteristics).
The switches are bidirectional, so the NO_ and COM_
pins can be either inputs or outputs.
Caution: Do not exceed the absolute maximum ratings
because stresses beyond the listed ratings may cause
permanent damage to the device.
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V
analog signals, especially if the analog signal is not
current limited.
