USB1T1104
Universal Serial Bus Peripheral Transceiver
with Voltage Regulator
General Description
Features
The USB1T1104 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
USB1T1104 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
Complies with Universal Serial Bus Specification 2.0
Integrated 5V to 3.3V voltage regulator for powering VBus
Utilizes digital inputs and outputs to transmit and receive USB
cable data
Supports full speed 12Mbits/s speed data rates
Ideal for portable electronic devices
the USB host (V
) to minimize the power consumed from the
BUS
local sources while used in devices with low supply voltages.
15kV contact HBM ESD protection on bus pins
3.3mm leadless package
The USB1T1104 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.
Industry standard HBCC footprint is lead-free

Functional Description
The USB1T1104 transceiver is designed to convert CMOS data
into USB differential bus signal levels and to convert USB differ-
ential bus signal to CMOS data.
Table 1 describes the specific pin functionality selection.
Table 2, Table 3, and Table 4 describe the specific Truth Tables
for Driver and Receiver operating functions.
To minimize EMI and noise the outputs are edge rate controlled
with the rise and fall times controlled and defined for full speed
data rates. The rise, fall times are balanced between the differ-
ential pins to minimize skew.
The USB1T1104 also has the capability of various power supply
configurations to support mixed voltage supply applications (see
Table 5) and Power Supply Configurations and Options for
detailed descriptions.

Power Supply Configurations and Options
The three modes of power supply operation are:
• Normal Mode: Regulated Output
3-STATE and the USB1T1104 allows external signals up to
3.6V to share the D and D bus lines. Internally the circuitry
limits leakage from D and D pins (maximum 10 A) and

connected to 5V (4.0V to 5.5V) and the internal voltage
regulator then produces 3.3V for the USB connections.
Pins Vbusmon and RCV are forced LOW as an indication of
this mode with Vbusmon being ignored during this state.
