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

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

Ω 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

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.
