aip74hc/hct244
octal buffer/line driver; 3-state

the aip74hc/hct244 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.
