The Si9241AEY is built on the Vishay Siliconix BiC/DMOS
process. An epitaxial layer prevents latchup.
The RX output is capable of driving CMOS or 1
The Si9241AEY is available in a space efficient 8-pin SO
package. It operates reliably over the automotive temperature
range (−40 to 125_C). The Si9241AEY is available in both
standard and lead (Pb)-free packages.
