1 Overview

The SN54SC8T138-SEP is a radiation-tolerant, 3-line to 8-line decoder/demultiplexer with logic level shifter. The input is designed with a lower threshold circuit to support up translation for lower voltage CMOS inputs (for example, 1.2V input to 1.8V output or 1.8V input to 3.3V output). In addition, the 5V tolerant input pins enable down translation (for example, 3.3V to 2.5V output).

For more information, see the SN54SC8T138-SEP product page.
