description/ordering information
The ’LVTH162244 devices are 16-bit buffers and line drivers designed for low-voltage (3.3-V) V
operation,
CC
but with the capability to provide a TTL interface to a 5-V system environment. These devices can be used as
four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. These devices provide true outputs and symmetrical
active-low output-enable (OE) inputs.
