Preliminary Datasheet General Purpose ITVS, 4 I/Os, CI/O-VSS<1.1pF, VCC General Description Features 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 AT1040 is a general purpose, high performance and low cost device suitable for protecting high speed data interfaces. The AT1040 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.
