Unisonic Technologies U74LVC257
The U74LVC257 is designed for 1.65V to 3.6V VCC operation. The U74LVC257 devices are designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable ( OE ) input is at a high logic level.| Part No. | U74LVC257 |
