General Description

The MAX3453E–MAX3456E ±15kV ESD-protected USB-

compliant transceivers interface low-voltage ASICs with

USB devices. The devices fully comply with USB 1.1

and USB 2.0 when operating at full (12Mbps) and low

(1.5Mbps) speeds. The MAX3453E–MAX3456E operate

with V

as low as +1.65V, ensuring compatibility with

low-voltage ASICs.

The MAX3453E–MAX3456E feature a logic-selectable

suspend mode that reduces current consumption to

less than 40µA. Integrated ±15kV ESD protection pro-

tects the USB D+ and D- bidirectional bus connections.

The MAX3453E supports only full-speed (12Mbps)

operation. The MAX3453E/MAX3454E feature an inter-

nal 1.5kΩ USB pullup resistor and an enumeration func-

tion that allows devices to logically disconnect while

plugged in. The MAX3453E/MAX3455E provide a push-

pull bus-detect (BD) output that asserts high when

BUS

> +4.0V.

The MAX3453E–MAX3456E operate over the extended

temperature range (-40°C to +85°C) and are available

in 14-pin TSSOP and 16-pin (3mm x 3mm) thin QFN

packages.

MAX3453E–MAX3456E ±15kV ESD-Protected USB Transceivers Detailed Description The MAX3453E–MAX3456E USB-compliant transceivers convert single-ended or differential logic-level signals to USB signals, and USB signals to single-ended or differential logic-level signals. The MAX3453E fully complies with full-speed (12Mbps) operation under USB specification 2.0. The MAX3454E–MAX3456E fully comply with USB specification 1.1, and full-speed (12Mbps) and lowspeed (1.5Mbps) operation under USB specification 2.0.

±15kV ESD-Protected USB Transceivers Sharing Mode Connect VL to a system power supply and leave VBUS (or VBUS and VTRM) unconnected or connect to GND. D+ and D- enter a tri-state mode, allowing other circuitry to share the USB D+ and D- lines, and VL consumes less than 20µA of supply current. D+ and D- withstand external signals up to +5.5V in sharing mode (Table 2). Device Control OE OE controls the direction of communication. Drive OE low to transfer data from the logic side to the USB side.

Connect SPD to VL to select the full-speed data rate (12Mbps). The MAX3454E provides an internal pullup resistor for selecting the bus speed. The MAX3455E and MAX3456E require an external pullup resistor to D+ or D- to set the bus speed. Connect the 1.
