General description
The 74HC240; 74HCT240 is a high-speed Si-gate CMOS device and is pin compatible
with Low-Power Schottky TTL (LSTTL).
The 74HC240; 74HCT240 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.
The 74HC240; 74HCT240 is similar to the 74HC244; 74HCT244 but has inverting
outputs.
