description/ordering information
These octal buffers / drivers are designed
specifically for low-voltage (3.3-V) VCC operation,
with the capability to provide a TTL interface to a
5-V system environment.

The ’LVTH241 devices are organized as two 4-bit
line drivers with separate output-enable (1OE,
2OE) inputs. When 1OE is low or 2OE is high, the
devices pass noninverted data from the A inputs
to the Y outputs. When 1OE is high or 2OE is low,
the outputs are in the high-impedance state.
