3 Description

The SN74LV8T541 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.
