description/ordering information
NC − No internal connection
These bus buffers 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 ’LVTH125 devices feature independent line drivers with 3-state outputs. Each output is in the
high-impedance state when the associated output-enable (OE) input is high.
