Description

These octal buffers and line drivers of LVTH244A are designed specifically for low-voltage (3.3-V) V_CC operation, but with the capability to provide a TTL interface to a 5-V system environment.

The 'LVTH244A devices are organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low, the LVTH244A pass data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
