MAX3451E Datasheet | Maxim Integrated

19-2843; Rev 2; 10/08 ±15k V ESD-Protected USB Transceivers MAX3450E/MAX3451E/MAX3452E General Description The MAX3450E/MAX3451E/MAX3452E USB-pliant transceivers interface low-voltage ASICs with USB devices. The devices fully ply 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 patibility with low-voltage ASICs. The MAX3450E/MAX3451E/MAX3452E feature a logicselectable suspend mode that reduces current consumption to less than 40µA. Integrated ±15k V ESD protection protects the USB D+ and D- bidirectional bus connections. The MAX3450E is pin patible 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 busdetect (BD) output that asserts high when VBUS is greater than +4.0V. The MAX3450E/MAX3451E/MAX3452E...
