1 Device Information

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 (V_CC) and supports 1.2-V, 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).
