3 Description

The SN74LV8T7541 is an octal buffer with open-drain

outputs.

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.
