3 Description

The SN74LV3T98-EP device features configurable

multiple functions with extended voltage operation

to allow for level translation.. The output state is

determined by eight patterns of 3-bit input. The user

can choose the logic functions MUX, AND, OR,

NAND, NOR, inverter, and noninverter. The output

level is referenced to the supply voltage (VCC) 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).
