Description

The 74HCT240 is a TTL input-level, 8-bit inverting buffer/line driver with 3-state outputs. The device can function as two 4-bit buffers or as a single 8-bit buffer. The device has two output enables (1OE and 2OE), each of which controls four of the three-state outputs. When nOE is HIGH, the outputs go into a high-impedance OFF state.

Clamp diodes are used as inputs. This allows for the use of current-limiting resistors to interface inputs to voltages greater than VCC.
