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 VL 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 protects
the USB D+ and D- bidirectional bus connections.
The MAX3453E supports only full-speed (12Mbps)
operation. The MAX3453E/MAX3454E feature an internal
1.5kΩ USB pullup resistor and an enumeration function
that allows devices to logically disconnect while
plugged in. The MAX3453E/MAX3455E provide a push-pull
bus-detect (BD) output that asserts high when
VBUS > +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.
