DESCRIPTION

The 74LV541 is a low–voltage CMOS device and is pin and function compatible with 74HC/HCT541.

The 74LV541 is an octal non-inverting buf fer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs OE

A HIGH on OEn causes the outputs to assume a high impedance OFF–state.

CL = 15pF VCC = 3.3V

and OE2.
