Product data sheet
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
.

Definitions
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
