MAX3344EEUE+

P1-P3P4-P6P7-P9P10-P12P13-P15
General Description
The MAX3344E/MAX3345E USB transceivers convert
logic-level signals to USB signals, and USB signals to
logic-level signals. An internal 1.5kΩ USB pullup resistor
supports full-speed (12Mbps) USB operation. The
MAX3344E/MAX3345E provide built-in ±15kV ESD-pro-
tection circuitry on the USB I/O pins, D+ and D-, and V
CC
.
The MAX3344E/MAX3345E operate with logic supply
voltages as low as 1.65V, ensuring compatibility with
low-voltage ASICs. The suspend mode lowers supply
current to less than 40µA. An enumerate function allows
devices to logically disconnect while plugged in. The
MAX3344E/MAX3345E are fully compliant with USB
specification 1.1, and full-speed operation under USB
specification 2.0.
The MAX3344E/MAX3345E have a USB detect that mon-
itors the USB bus for insertion and signals this event. The
MAX3344E USB_DET threshold is between 3.6V (min)
and 4V (max), while the MAX3345E USB_DET threshold
is between 1V (min) and 2.8V (max).
The MAX3344E/MAX3345E are available in the miniature
4
✕
4 UCSP™, as well as the small 16-pin TSSOP, and
are specified over the extended temperature range,
-40°C to +85°C.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
