AT1140
General Description
Features
BCD ITVS (Integrated Transient Voltage Suppression)
devices are designed and built using BCD proprietary
process technology. These devices integrate the
various diodes, transistors and resistors into the BCD
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 AT1140 is a general purpose, high
performance device suitable for protecting four high
speed I/Os. These devices are assembled in DFN
packages for operation at higher frequencies
minimizing distortion to the lines being protected.
The AT1140 is available in the DFN-2.5×1.0-10
package. This package allows simple and optimal
placement in existing high-speed PCB layouts.
