Overview

  • ±15kV ESD Protection on D+ and D-
  • Internal Linear Regulator Allows Direct Powering from the USB Cable
  • Internal 1.5kΩ Pullup Resistor for Low/Full-Speed Operation
  • Supports Low-Speed and Full-Speed USB Communications
  • Complies with USB Specification Revision 1.1 and 2.0 (Low Speed and Full Speed)
  • Three-State Outputs
  • Enumerate Input—Allows USB Connection through Software
  • No Power-Supply Sequencing Required
  • Operates with VL of 1.65V to 3.6V, Ensuring Compatibility with Low-Voltage ASICs
  • Available in Miniature Chip-Scale Package

The MAX3346E bidirectional transceiver converts logic-level signals to USB signals, and USB signals to logic-level signals. The MAX3346E includes the 1.5kΩ USB pullup resistor internally, and supports both full-speed (12Mbps) and low-speed (1.5Mbps) USB operation. The device has built-in ±15kV ESD protection circuitry to guard the USB I/O pins, D+ and D-.

The MAX3346E operates with VL voltages as low as 1.65V, ensuring compatibility with low-voltage ASICs. The device features a logic-selectable suspend mode that lowers current draw to less than 40µA. The MAX3346E has an enumerate function that allows devices to logically disconnect while plugged in. The MAX3346E is fully compliant with USB specification 1.1, and the full-speed and low-speed operation under USB specification 2.0.

The MAX3346E is available in the miniature 4 x 4 chip-scale package (UCSP™), as well as the small 14-pin TSSOP, and is rated for the -40°C to +85°C extended temperature range.
