SN74LVC125APWR from TI is a quad 3-state bus buffer. 1.65-3.6V supply with 5V tolerant inputs. 4.5ns propagation. Active-low output enable per channel pair.<\/p>\n

\u5de5\u4f5c\u539f\u7406<\/h2>\n

Each buffer passes input to output when enabled (OE low). When OE high, output goes high-impedance (3-state). 5V tolerant inputs allow interfacing with 5V logic from 3.3V supply.<\/p>\n
