MAX3344E/MAX3345E 19-3171 Rev 0 2/04 15kV ESD-Protected USB Transceivers in UCSP with USB Detect General Description Features The MAX3344E/MAX3345E USB transceivers convert 15kV ESD Protection On D+ and D- logic-level signals to USB signals, and USB signals to Comply with USB Specification 1.1 (Full Speed 2.0) logic-level signals. An internal 1.5k USB pullup resistor Separate VP and VM Inputs/Outputs supports full-speed (12Mbps) USB operation. The V Down to 1.65V Allows Connection with Low- L MAX3344E/MAX3345E provide built-in 15kV ESD-pro- Voltage ASICs tection circuitry on the USB I/O pins, D+ and D-, and V . CC Enumerate InputAllows USB Connection The MAX3344E/MAX3345E operate with logic supply through Software voltages as low as 1.65V, ensuring compatibility with USB Detect Function low-voltage ASICs. The suspend mode lowers supply current to less than 40A. An enumerate function allows 3.6V (min) to 4V (max)MAX3344E devices to logically disconnect while plugged in. The 1V (min) to 2.8V (max)MAX3345E MAX3344E/MAX3345E are fully compliant with USB Allow Single-Ended or Differential Logic I/O specification 1.1, and full-speed operation under USB Internal Linear Regulator Allows Direct Powering specification 2.0. from the USB The MAX3344E/MAX3345E have a USB detect that mon- Internal Pullup Resistor for Full-Speed Operation itors the USB bus for insertion and signals this event. The Three-State Outputs MAX3344E USB DET threshold is between 3.6V (min) No Power-Supply Sequencing Required and 4V (max), while the MAX3345E USB DET threshold is between 1V (min) and 2.8V (max). Driver Active in Suspend Mode Available in Miniature Chip-Scale Package The MAX3344E/MAX3345E are available in the miniature 4 4 UCSP, as well as the small 16-pin TSSOP, and are specified over the extended temperature range, Ordering Information -40C to +85C.
