Preliminary Datasheet Higher Surge ITVS, 4 I/Os, CI/O-VSS<1.5pF, with 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 AT1041 is a general purpose, high performance and low cost device exhibiting higher surge capability, suitable for protecting high speed data interfaces. The AT1041 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.
