APPLICATION INFORMATION
TVC background information
In personal computer (PC) architecture there are industry-accepted bus standards. These standards define,
among other things, the I/O voltage levels at which the bus communicates. Examples include the GTL+ host
bus, the AGP graphics port, and the PCI local bus. In new designs, the system components must communicate
with existing bus infrastructure. Providing an evolutionary upgrade path is important in the design of PC
architecture, but the existing bus standards must be preserved.
To achieve the ever-present needs for smaller, faster, lighter devices that draw less power, yet have faster
performance, most new high-performance digital integrated circuits are being designed and produced with
advanced submicron semiconductor process technologies. These devices have thin gate-oxide or short
channel lengths and very low absolute-maximum voltages that can be tolerated at the inputs/outputs (I/Os)
without causing damage. In many cases, the I/Os of these devices are not tolerant of the high-state
voltage-levels on the pre-existing buses with which they must communicate. Therefore, the need arose for
protection of the I/Os of devices by limiting the I/O voltages.
The Texas Instruments (TI
) Translation Voltage Clamp (TVC) family was designed for the specific application
of protecting sensitive I/Os (see Figure 2). The information in this data sheet describes the I/O protection
application of the TVC family and should enable the design engineer to successfully implement an I/O protection
circuit utilizing the TI TVC solution.
