1. General description

The 74HC240-Q100; 74HCT240-Q100 is a high-speed Si-gate CMOS device and is pin compatible

with Low-Power Schottky TTL (LSTTL).

The 74HC240-Q100; 74HCT240-Q100 is a dual octal inverting buffer/line driver with 3-state

outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on

nOE causes the outputs to assume a high impedance OFF-state.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
