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. In puts are over voltage tolerant. This
feature allows th e us e of th es e de vice s as tr an sla to rs in mix ed voltage enviro nm e nts.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
