POST OFFICE BOX 655303
DALLAS, TEXAS 75265
APPLICATION INFORMATION
features and benefits
The TVC family has several features that benefit a system designer when implementing a sensitive I/O
protection solution. Table 1 lists these features and their associated benefits.
Table 1. Features and Benefits
FEATURES
BENEFITS
Any FET can be used as the reference transistor
Ease of layout
All FETs on one die, tight process control
Very low spread of VO relative to VREF
No logic power supply (VCC) required
Ease of trace routing
No active control logic (passive device)
Flow-through pinout
Devices offered in different bit-widths and packages
Optimizes design and cost effectiveness
Designer flexibility with VREF input
Allows migration to lower-voltage I/Os without board redesign
conclusion
The TI TVC family provides the designer with a solution for protection of circuits with I/Os that are sensitive to
high-state voltage-level overshoots. The flexibility of TVC enables a low-voltage migration path for advanced
designs to align with industry standards.
frequently asked questions (FAQ)
1.
Q: Can any of the transistors in the array be used as the reference transistor
A: Yes, any transistor can be used as long as its V
BIAS
pin is connected to the GATE pin.
Q: In the recommended operating conditions table of the data sheet, the typical V
BIAS
is 3.3 V.
Should V
BIAS
be equal to or greater than V
REF
on the reference transistor
A: V
BIAS
is a variable that is determined by V
REF
. V
BIAS
is connected to V
DD
through a resistor to allow the
bias voltage to be controlled by V
REF
. V
DD
can be as high as 5.5 V. V
REF
needs to be at least 1 V less
than V
BIAS
on the reference transistor.
Q: Do both A and B ports have 5-V I/O tolerance or is 5-V I/O tolerance provided only on the low-voltage
side
2.
3.
A: Both ports are 5-V tolerant.
