The SN54SC4T125-SEP contains four
independent buffers with 3-state outputs and extended voltage
operation to allow for level translation. Each buffer performs the
Boolean function Y = A in positive logic. The outputs can be put
into a high impedance (Hi-Z) state by applying a HIGH on the
OE pin. The output level is referenced
to the supply voltage (V CC) 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). In addition, the 5-V tolerant input pins
enable down translation (for example, 3.3 V to 2.5 V output).
