3 Description

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).
