±±5ꢀk EꢁDꢂ-rotected UꢁB Transceivers
General Description
Features
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
ꢀ
15kV ESD Protection on D+ and D-
ꢀ USB 1.1 and USB 2.0 (Low-Speed and Full-Speed)-
Compliant Transceivers
ꢀ Combined VP and VM Inputs/Outputs
with V as low as +1.65V, ensuring compatibility with
L
ꢀ +1.65V to +3.6V V Logic Supply Input for

low-voltage ASICs.
Interfacing 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.
ꢀ Enumerate Input Function (MAX3453E/MAX3454E)
ꢀ Powered from Li+ Battery as Low as +3.1V
(MAX3454E/MAX3456E)
The MAX3453E supports only full-speed (12Mbps)
operation. The MAX3453E/MAX3454E feature an inter-
nal 1.5k 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

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.
