3 Description

The SN54SC4T00-SEP contains four independent 2-

input NAND Gates with Schmitt-trigger inputs. Each

gate performs the Boolean function Y = A ● B in

positive logic. The output level is referenced to the

supply voltage (VCC) and supports 1.8-V, 2.5-V, 3.3-V,

and 5-V CMOS levels.

The input is designed with a lower threshold circuit to

support up translation for lower voltage CMOS inputs

(for example 1.2 V input to 1.8 V output or 1.8 V input

to 3.3 V output). Additionally, the 5-V tolerant input

pins enable down translation (for example 3.3 V to 2.5

V output).
