MAX3346E 19-3172 Rev 0 2/04 15kV ESD-Protected USB Transceiver in UCSP General Description Features The MAX3346E bidirectional transceiver converts logic- 15kV ESD Protection on D+ and D- level signals to USB signals, and USB signals to logic- Internal Linear Regulator Allows Direct Powering level signals. The MAX3346E includes the 1.5k USB from the USB Cable pullup resistor internally, and supports both full-speed Internal 1.5k Pullup Resistor for Low/Full-Speed (12Mbps) and low-speed (1.5Mbps) USB operation. The device has built-in 15kV ESD protection circuitry Operation to guard the USB I/O pins, D+ and D-. Supports Low-Speed and Full-Speed USB The MAX3346E operates with V voltages as low as L Communications 1.65V, ensuring compatibility with low-voltage ASICs. Complies with USB Specification Revision 1.1 and The device features a logic-selectable suspend mode 2.0 (Low Speed and Full Speed) that lowers current draw to less than 40A. The Three-State Outputs MAX3346E has an enumerate function that allows Enumerate InputAllows USB Connection devices to logically disconnect while plugged in. The MAX3346E is fully compliant with USB specification 1.1, through Software and the full-speed and low-speed operation under USB No Power-Supply Sequencing Required specification 2.0. Operates with V of 1.65V to 3.6V, Ensuring L The MAX3346E is available in the miniature 4 x 4 chip- Compatibility with Low-Voltage ASICs TM scale package (UCSP ), as well as the small 14-pin Available in Miniature Chip-Scale Package TSSOP, and is rated for the -40C to +85C extended temperature range.
