1. General description

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.

2. Features and benefits
