The 74HCT367D,652 is a hex non-inverting Buffer/Line Driver with 3-state outputs. The 3-state outputs (nY) are controlled by the output enable inputs (1OE, 2OE). It is high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). A HIGH on nOE causes the outputs to assume a high impedance OFF-state. The 367 is identical to the 368 but has non-inverting outputs.
