Detailed Description
The MAX3344E/MAX3345E are bidirectional transceivers
that convert single-ended or differential logic-level signals
to differential USB signals, and convert differential USB
signals to single-ended or differential logic-level signals.
The MAX3344E/MAX3345E are operational from V
CC
=
5.5V to V
CC
= 3V (electrical specifications are not guaran-
teed for V
CC
< 4V). Both devices include an internal
1.5k
pullup resistor that connects and disconnects D+
to VTRM (see the
Functional Diagram
).
The MAX3344E/MAX3345E are tolerant to power seq-
uencing 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 MAX3344E/MAX3345E can receive USB
power (V
CC
) directly from the USB connection and
operate with logic supplies (V
L
) down to 1.65V, while
still meeting the USB physical layer specifications. The
MAX3344E/MAX3345E support full-speed (12Mbps)
USB specification 2.0 operation.
The MAX3344E/MAX3345E have an enumerate feature
that functions when power is applied. Driving ENUM low
disconnects the internal 1.5k
pullup resistor from D+
enumerating the USB. This is useful if changes in commu-
nication protocol are required while power is applied, and
while the USB cable is connected.
