Product data sheet
1. General description
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.
