The SN54SC4T02-SEP
contains four independent 2-input NOR Gates with extended voltage operation to allow for
level translation. 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).
