General Description  
Features  
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/

Interfacing with Low-Voltage ASICs

Enumerate Input Function (MAX3451E)  
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  
1.5kUSB pullup resistor and an enumeration function  
that allows devices to logically disconnect while  
plugged in. The MAX3452E provides a push-pull bus-
