The MAX3450E/MAX3451E/MAX3452E 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 MAX3450E/MAX3451E/
MAX3452E operate with V
compatibility with low-voltage ASICs.
The MAX3450E/MAX3451E/MAX3452E feature a logic-
selectable suspend mode that reduces current con-
sumption to less than 40µA. Integrated ±15kV ESD
protection protects the USB D+ and D- bidirectional
bus connections. The MAX3450E is pin compatible with
Micrel’s MIC2550A. The MAX3451E features an internal
1.5kΩ USB pullup resistor and an enumeration function
that allows devices to logically disconnect while
plugged in. The MAX3452E provides a push-pull bus-
detect (BD) output that asserts high when V
greater than +4.0V.
The MAX3450E/MAX3451E/MAX3452E operate over the
-40°C to +85°C extended temperature range and are
available in 14-pin TSSOP and 3mm x 3mm 16-pin Thin
QFN packages.
