74AHCT240-Q100

Octal buffer/line driver; inverting; 3-state

The 74AHCT240-Q100 is an 8-bit inverting buffer/line drivers with 3-state outputs. This device can be used as two 4-bit buffers or one 8-bit buffer. It 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 are over voltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
