AP54RHC5942
Radiation-Hardened 8-Bit Serial-In Parallel-Out Shift Register
AP54RHC5942
The AP54RHC5942 is a radiation-hardened by design 8-bit shift register, serial-in parallel-out (SIPO), with output latch that is ideally suited for commercial space and other applications demanding radiation tolerance and high reliability. It has myriad applications including IO expansion, data-buffering, serial-to-parallel conversion, and more.
This device is a member of the Apogee Semiconductor AP54RHC logic family operating across a voltage supply range of 1.4 V to 5.5 V. Its wide voltage range support and logic level down translation enable flexible system integration.
