±15kV ESD-Protected USB Transceivers
MAX3450E/MAX3451E/MAX3452E
General Description
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 VL as low as +1.
65V, ensuring compatibility with low-
voltage ASICs.
The MAX3450E/MAX3451E/MAX3452E feature a logicselectable suspend mode that reduces current consumption 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.
