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

The SN54SC6T14-SEP device

contains six independent Inverters with

Schmitt-trigger inputs and extended voltage

operation to allow for level translation. Each gate

performs the Boolean function Y =

A in positive logic. The

output level is referenced to the supply voltage

(VCC) and supports 1.2V, 1.8-V, 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).
