DESCRIPTION
The TPD4S1394 provides robust system level ESD
solution for the IEEE.1394 port along with a live
insertion detection mechanism for high-speed lines
interfacing a low-voltage, ESD sensitive core chipset.
This device protects and monitors up to two
differential input pairs. The optimized line capacitance
allows to protect the data lines with data rate in
excess of 1.6 GHz without degrading signal integrity.
The TPD4S1394 incorporates a live insertion circuit
whose output state changes when improper voltage
levels are present on the input data lines. The
FWPWR_EN signal controls an external FireWire port
power switch. During the live insertion event if there
is a floating GND or a high level signal at the D+, D–
pins, the internal comparator will detect the changes
and pull the FWPWR_EN signal to low state. When
FWPWR_EN is driven low, there is an internal delay
mechanism preventing it from being driven to the high
state regardless of the inputs to the comparator.
Additionally, the TPD4S1394 performs ESD
protection on the four inputs pins: D1+, D1–, D2+,
and D2–. The TPD4S1394 conforms to the
IEC61000-4-2 (Level 4) ESD protection and ±15 kV
HBM ESD protection. The TPD4S1394 is
characterized for operation over ambient air
temperature of –40°C to 85°C.
A 0.1uF decoupling capacitor is required at VCC

TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
