Description
The Intersil HS-54C138RH is a radiation hardened 3- to 8-line decoder fabricated using a radiation hardened EPI-CMOS process. It features low power consumption, high noise immunity, and high speed. Also featured are pin and function compatibility with the 54LS138 industry standard part. The HS-54C138RH is ideally suited for high speed memory chip select address decoding. It is intended for use with the Intersil HS-80C85RH radiation hardened microprocessor, but it can also be utilized as a demultiplexer in any low power rad-hard application.
