Detailed Description
The MAX3346E is a bidirectional transceiver that con-
verts single-ended or differential logic-level signals to
differential USB signals, and converts differential USB
signals to single-ended or differential logic-level sig-
nals. The MAX3346E includes an internal 1.5k
pullup
resistor that can be connected to either D+ or D- for
full-speed or low-speed operation (see the
Functional
Diagram
). The MAX3346E can be energized without
concern about power-supply sequencing. Additionally,
the USB I/O, D+ and D-, are ESD protected to ±15kV.
The MAX3346E can get its USB-side power, V
CC
,
directly from the USB connection, and can operate with
system-side power, V
L
, down to 1.65V and still meet the
USB physical layer specifications. The MAX3346E sup-
ports both full-speed (12Mbps) and low-speed
(1.5Mbps), USB specification 1.1 operation.
The MAX3346E has an enumerate feature that works
when power is on. Driving ENUM low disconnects the
internal 1.5k
pullup resistor from both D+ and D-,
reenumerating the USB. This is useful if changes in com-
munication protocol are required while power is applied,
and while the USB cable is connected.

B2
SUSP
Input
Suspend Input. Drive SUSP low for normal operation. Force SUSP high for low-
power state. In low-power state RCV is low, D+/D- are high impedance if
OE
is
floating, and VP/VM are active outputs.

A2
SPEED
Input
USB Transmission Speed Select Input. If SPEED is forced high, full speed
(12Mbps) is selected and the internal 1.5k
pullup resistor is connected to D+.
If SPEED is forced low, low speed (1.5Mbps) is selected and the internal 1.5k
pullup resistor is connected to D-.

System-Side Power-Supply Input. Connect to the system’s logic-level power
supply, 1.65V to 3.6V. Bypass to GND with a 0.1μF capacitor.
