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.
