74HC125D,653 NEXPERIA Quad Buffer/Line Driver IC (SOIC-14)

Most buffer chips only ever drive their output high or low, but the 74HC125 adds a third option on each of its four independent channels, a tri-state output that can disconnect entirely and let another device drive that same line. That makes it the right chip whenever several devices need to share one bus line and take turns driving it, rather than fighting each other for control, all from one genuine Nexperia SOIC-14 chip.
