1. General description

The 74HC240; 74HCT240 is an 8-bit inverting 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. This enables the use of current

limiting resistors to interface inputs to voltages in excess of VCC.
