3 Description

The SN74LV4T32-Q1 contains four independent 2-

input OR 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). In addition, the 5-V tolerant input pins

enable down translation (for example, 3.3 V to 2.5 V

output).
