Unisonic Technologies U74HC540
The U74HC540 combines with octal buffers and line drivers with inverting 3-state outputs. The 3-state output is controlled by output enable inputs OE1 and OE2 , all eight outputs will be in high-impedance when either of the 2 inputs is applied with high voltage. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.| Part No. | U74HC540 |
