MAX4983E/MAX4984E
Detailed Description
The MAX4983E/MAX4984E are ±15kV ESD-protected
DPDT analog switches. The devices are ideal for USB
2.0 Hi-Speed (480Mbps) switching applications and
also meet USB low- and full-speed requirements.
The MAX4983E/MAX4984E are fully specified to oper-
ate from a single +2.8V to +5.5V supply. The low VIH
threshold of the devices permits them to be used with
logic levels as low as 1.4V. The MAX4983E/MAX4984E
are based on a charge-pump-assisted n-channel archi-
tecture. The devices feature a shutdown mode to
reduce the quiescent current to less than 0.1A (typ).
Digital Control Input
The MAX4983E/MAX4984E provide a single-bit control
logic input, CB. CB controls the position of the switches
as shown in the
Functional Diagram/Truth Table.
Driving CB rail-to-rail minimizes power consumption.
With a +2.8V to +5.5V supply voltage range, the device
is +1.4V logic compatible.
Analog Signal Levels
The on-resistance of the MAX4983E/MAX4984E is very
low and stable as the analog input signals are swept
from ground to VCC (see the Typical Operating Character-
istics). These switches are bidirectional, allowing NO_,
NC_, and COM_ to be configured as either inputs or
outputs. The charge-pump-assisted n-channel architec-
ture allows the switch to pass analog signals that
exceed VCC up to the overvoltage fault protection
threshold. This allows USB signals that exceed VCC to
pass, allowing compliance with USB requirements for
voltage levels.
Overvoltage Fault Protection
The MAX4983E/MAX4984E feature overvoltage fault pro-
tection on COM_. Fault protection protects the switch and
USB transceiver from damaging voltage levels. When
voltages on COM exceed the fault protection threshold,
(VFP), COM_, NC_ and NO_ are high impedance.
Enable Input
The MAX4983E/MAX4984E feature a shutdown mode that
reduces the supply current to less than 0.1A and places
COM_ in high impedance. Drive EN high for the
MAX4983E or EN low for the MAX4984E to place the
devices in shutdown mode. When EN is driven low or EN
is driven high, the devices are in normal operation.
Applications Information
USB Switching
The MAX4983E/MAX4984E analog switches are fully com-
pliant with the USB 2.0 specification. The low on-resis-
tance and low on-capacitance of these switches make
them ideal for high-performance switching applications.
