Terminal Descriptions
The USB1T1103 transceiver is designed to convert
CMOS data into USB differential bus signal levels and to
convert USB differential bus signal to CMOS data.
nals rather than discrete input and output terminals.
Table 1 describes the specific terminal functionality
selection. Table 2 and Table 3 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 only (12Mbits/s). The
rise, fall times are balanced between the differential terminals to minimize skew.
The USB1T1103 also has the capability of various power
supply configurations, including a disable mode for
VCCIO disconnected, to support mixed voltage supply
applications (see Table 4) and Section 2.1 for detailed
descriptions.
The USB1T1103 differs from earlier USB Transceiver in
that the Vp/Vm and Vpo/Vmo terminals are now I/O termi-

USB1T1103 Universal Serial Bus Peripheral Transceiver with Voltage Regulator
Functional Description
external signals up to 3.6V to share the D+ and D- bus
lines. Internally the circuitry limits leakage from D+ and
D- terminals (maximum 10µA) and VCCIO such that
device is in low power (suspended) state. Terminals
Vbusmon and RCV are forced LOW as an indication of
this mode with Vbusmon being ignored during this state.
The three modes of power supply operation are:
Normal Mode: Regulated Output and Regulator Bypass
1.
Regulated Output: VCCIO is connected and VCC(5.0)
is connected to 5V (4.0V to 5.5V) and the internal
voltage regulator then produces 3.3V for the USB
connections.
2.
Internal Regulator Bypass Mode: VCCIO is connected and both VCC(5.0) and VREG(3.3) are connected to a 3.3V source (3.0V to 3.6V).
Disable Mode: VCCIO is not connected. VCC is connected, or VCC and VREG are connected. 0V to 3.3V in
this mode D+ and D- are 3-STATE and VPU is HIGH
Impedance (switch is turned off). The USB1T1103 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 10µ A).
In both cases, for normal mode, the VCCIO is an independent voltage source (1.65V to 3.6V) that is a function of
the external circuit configuration.
A summary of the Supply Configurations is described in
Table 4.
Sharing Mode: VCCIO is only supply connected. VCC
and VREG are not connected. In this mode, the D+ and
D- terminals are 3-STATE and the USB1T1103 allows

Human Body Model ESD event. Figure 4 is the ideal

ESD Protection: D+/D- Terminals
The IEC 61000-4-2 standard covers ESD testing and
performance of finished equipment and evaluates the
equipment in its entirety for ESD immunity. Fairchild
Semiconductor has evaluated this device using the
IEC 6100-4-2 representative system model depicted in
Figure 5. Under the additional standards set forth by the
IEC, this device is also compliant with IEC 60749-26
(HBM) and IEC 60749-27 (MM).
Since the differential terminals of a USB transceiver may
be subjected to extreme ESD voltages, additional immunity has been included in the D+ and D- terminals without compromising performance. The USB1T1103
differential terminals have ESD protection to the following limits:
■ 15kV using the contact Human Body Model
Additional ESD Test Conditions
■ 8kV using the Contact Discharge method as specified
in IEC 61000-4-2
For additional information regarding our product test
methodologies and performance levels, please contact
