±±15k EꢀDꢁ-rotected UꢀB Transceiver

in UCꢀ-

General Description

Features

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 15kꢀ ESꢁ protection circuitry

to guard the USB I/O pins, ꢁ+ and ꢁ-.

♦ ±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

The MAX3346E operates with ꢀ voltages as low as

1.65ꢀ, 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.

♦ 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 V of 1.65V to 3.6V, Ensuring

The MAX3346E is available in the miniature 4 x 4 chip-

Compatibility with Low-Voltage ASICs

scale package (UCSP ), as well as the small 14-pin

♦ Available in Miniature Chip-Scale Package

TSSOP, and is rated for the -40°C to +85°C extended

temperature range.
