±15kV ESD-Protected USB Level Translators in
UCSP
General Description
The MAX3340E/MAX3343E bidirectional level transla-
tors convert logic-level signals to USB signals, and USB
signals to logic-level signals. They include the 1.5kΩ
USB termination resistor internally, and support both
full-speed (12Mbps) and low-speed (1.5Mbps) USB
operation. They have built-in ±15kV ESD protection cir-
cuitry to guard the USB I/O pins, D+ and D-.
The MAX3340E/MAX3343E operate with V
L
at voltages
as low as 1.8V, ensuring compatibility with low-voltage
ASICs. The MAX3340E/MAX3343E feature a logic-
selectable suspend mode that lowers current draw to
less than 200µA. The MAX3340E/MAX3343E have a
unique reenumerate feature that allows changes in USB
communication protocol while the power is on. The
MAX3340E/MAX3343E are fully compliant with USB
specification 1.1, and the full-speed and low-speed
operation under USB specification 2.0.
The MAX3340E/MAX3343E are available in the minia-
ture 4 x 4 chip-scale package, as well as the small 14-
pin TSSOP, and are rated for the -40°C to +85°C
extended temperature range.

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.

Note 1:
Parameters are 100% production tested at 25°C, limits over temperature are guaranteed by design.
Note 2:
Logic side refers to RCV, VP, VM, SUSP, SPEED, MODE, RENB, OE/ENUMERATE,
OE,
and ENUMERATE.
Note 3:
Excludes external resistors. In order to comply with USB specification 1.1, external 24Ω (±1%) series resistors are recom-
mended at D+ and D-.
Note 4:
Not guaranteed if VP = VM = high.
Note 5:
Guaranteed by design, not production tested.
