ONSEMI MM74HC126MX CMOS Buffer

The MM74HC125 and MM74HC126 are high-speed CMOS non-inverting 3-STATE buffers capable of driving large bus capacitances with high drive current outputs. They feature propagation delays around 13 ns, operate over a voltage range of 2V to 6V, and consume minimal power with low input and quiescent currents. The devices support fanout of 15 LS-TTL loads, with control inputs enabling high impedance states. Designed for high-speed digital applications, they are available in various packages including SOIC, SOP, TSSOP, and PDIP, suitable for space-constrained circuits requiring reliable, fast signal buffering.
