±15kV ESD-Protected USB Transceivers
General Description
The MAX3453E–MAX3456E ±15kV ESD-protected USB-
compliant transceivers interface low-voltage ASICs with
USB devices. The devices fully comply with USB 1.1
and USB 2.0 when operating at full (12Mbps) and low
(1.5Mbps) speeds. The MAX3453E–MAX3456E operate
with V
L
as low as +1.65V, ensuring compatibility with
low-voltage ASICs.
The MAX3453E–MAX3456E feature a logic-selectable
suspend mode that reduces current consumption to
less than 40µA. Integrated ±15kV ESD protection pro-
tects the USB D+ and D- bidirectional bus connections.
The MAX3453E supports only full-speed (12Mbps)
operation. The MAX3453E/MAX3454E feature an inter-
nal 1.5kΩ USB pullup resistor and an enumeration func-
tion that allows devices to logically disconnect while
plugged in. The MAX3453E/MAX3455E provide a push-
pull bus-detect (BD) output that asserts high when
V
BUS
> +4.0V.
The MAX3453E–MAX3456E operate over the extended
temperature range (-40°C to +85°C) and are available
in 14-pin TSSOP and 16-pin (3mm x 3mm) thin QFN
packages.

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.
