Radiation-tolerant six-bit fixed-direction level translator with Schmitt-trigger inputs

The SN54SC6T17-SEP

device

contains six independent Buffers with

Schmitt-trigger inputs. Each gate performs the

Boolean function Y = A in positive logic. The output

level is referenced to the supply voltage

(VCC) and supports 1.8V, 2.5V, 3.3V,

and 5V CMOS levels.

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). Additionally, the 5V tolerant input pins enable down translation (for example 3.3V to 2.5V output).
