These bus buffers are designed specifically for low-voltage (3.3-V) VCCoperation, 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.
Support Mixed-Mode Signal Operation (5-V Input and Output Voltages With 3.3-V VCC)
Support Unregulated Battery Operation Down to 2.7 V
Typical VOLP(Output Ground Bounce)
<0.8 V at VCC= 3.3 V, TA= 25°C
Ioff and Power-Up 3-State Support Hot Insertion
Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors
