The 74LV541 is an octal non-inverting buffer/line driver with 3-State outputs. The 3-State outputs are controlled by the output enable inputs OE1 and OE2. A HIGH on OEn causes the outputs to assume a high impedance OFF-state. CONDITIONS CL = 15pF VCC = 3.3V VI = GND to VCC 1 TYPICAL 10 3.5 37 UNIT ns pF pF NOTES: 1.
