USB1T1105A

Universal Serial Bus Peripheral Transceiver

with Voltage Regulator

General Description

The USB1T1105A is an Universal Serial Bus Specification Rev

2.0 compliant transceiver. The device provides an USB inter-

face

for

Full-Speed

(12Mbit/s)

USB

applications.

The

USB1T1105A provides excellent flexibility, allowing differential

and single ended inputs while an integrated voltage regulator

sets the I/O level to 1.65V to 3.6V. Utilizing an integrated 5.0V to

3.3V voltage regulator, the part can be powered directly from

local sources while used in devices with low supply voltages.

The USB1T1105A provides 15kV ESD protection on the USB

bus pins (D

/D). This eliminates the need for any external ESD

devices while providing excellent protection to larger and more

expensive ASICs and USB controllers.
