The 74HC244; 74HCT244 is an 8-bit buffer/line driver with 3-state outputs.

The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables (1OE and 2OE), each controlling four of the 3-state outputs. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.

Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC.
