74F125 and 74F126 are two quad buffers that support 3-state operation mode. They have high impedance NPN base inputs for reduced loading, typical propagation delay of 5.0ns, and typical supply current of 23mA (74F125) and 26mA (74F126). They can be used in the commercial range, with VCC of 5V ±10%, and Tamb of 0°C to +70°C. Their packaging is 14-pin plastic DIP (N74F125N and N74F126N), 14-pin plastic SO (N74F125D and N74F126D), and SOT108-1.
