General Purpose ITVS, 4 I/Os, CI/O-VSS<1.5pF
AT2042
General Description
BCD ITVS (Integrated Transient Voltage Suppression)
devices are designed and built using a BCD
proprietary process based on BCD standard
technology. These devices integrate the various diodes,
transistors and resistors required to build these ITVS
products. These diodes and transistors feature low
parasitic resistance and the diodes also exhibit low
capacitance. Using these devices, BCD is able to
design voltage clamping products where low
capacitance associated with low dynamic resistance is
required.
The BCD AT2042 is a general purpose, high
performance and low cost device suitable for
protecting high speed data interfaces. The AT2042 is a
unique design integrating low capacitance steering
diodes and a clamping cell, specially created to protect
sensitive components connected to data and
transmission lines.
The AT2042 is available in SOT-23-6 package. This
package allows simple and optimal placement in
existing high-speed PCB layout.
