USB1T1105A
Universal Serial Bus Peripheral Transceiver
with Voltage Regulator
www.DataSheet4U.com
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
the USB host (VBUS) to minimize the power consumed from the
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.

Note 6: The Absolute Maximum Ratings are those values beyond which the safety of
the device cannot be guaranteed. The device should not be operated at these limits.
The parametric values defined in the Electrical Characteristic tables are not guaran-
teed at the absolute maximum rating. The “Recommended Operating Conditions”
table will define the conditions for actual device operation.
Note 7: IO Absolute Maximum Rating must be observed.
