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 1.5k
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
V
BUS
> +4.0V. The MAX3456E is pin compatible with
Micrel’s MIC2550A.
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.
