aip74hc/hct640
octal bus transceiver; 3-state; inverting

the aip74hc/hct640 is an 8-bit inverting transceiver with 3-state outputs. the device features an output enable (oe()) and send/receive (dir) for direction control. a high onoe() causes the outputs to assume a high-impedance off-state. inputs include clamp diodes. this enables the use of current limiting resistors to interface inputs to voltages in excess of vcc.
