Detailed Description
The MAX3341E is a bidirectional level translator that
converts single-ended or differential logic-level signals
to differential USB signals, and converts differential
USB signals to single-ended or differential logic-level
signals. The MAX3341E includes an internal 1.5k
pullup resistor that connects and disconnects D+ to
VTRM (
Functional Diagram
). The MAX3341E is tolerant
to power sequencing with either V
CC
> V
L
or V
L
> V
CC
.
Additionally, the USB I/O, D+ and D-, and V
CC
are ESD
protected to ±15kV. The MAX3341E can receive USB
power (V
CC
) directly from the USB connection, and
operates with logic supplies (V
L
) down to 1.8V while still
meeting the USB physical layer specifications. The
MAX3341E supports full-speed (12Mbps) USB specifi-
cation 2.0 operation.
The MAX3341E has a unique enumerate feature that
functions when power is applied. Driving ENUM low
disconnects the internal 1.5k
termination resistor from
D+ enumerating the USB. This is useful if changes in
communication protocol are required while power is
applied, and while the USB cable is connected.
