3 Description

The SN74LV8T541-Q1 contains eight buffers with 3-state outputs. The active low output enable pins (OE1 and OE2) control all eight channels, and are configured so that both must be low for the outputs to be active.

The input is designed with a reduced threshold circuit to support up translation when the supply voltage is larger than the input voltage. Additionally, the 5V tolerant input pins enable down translation when the input voltage is larger than the supply voltage. The output level is always referenced to the supply voltage (VCC) and supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels.
