Overview
HD74HCT125/HD74HCT126 Quad.
Bus Buffer Gates (with 3-state outputs) Description The HD74HCT125, HD74HCT126 require the 3-state control input C to be taken high to put the output into the high impedance condition, whereas the HD74HCT125, HD74HCT126 requires the control input to be low to put the output into high impedance.
