Quad buffer with 3-state control
The SN74LVC125ADT from Texas Instruments is a quad non-inverting buffer with independent 3-state outputs, each capable of sinking or sourcing 24 mA.
Supply voltage and drive strength
The 24 mA output drive at both high and low levels is consistent across the full supply range — the buffer does not reduce drive as VCC drops to 1.65 V, which is useful for level-shifting from a low-voltage FPGA bank to a 3.3 V peripheral. Each of the four elements handles one bit, so the part replaces four discrete single-gate buffers in a single 14-SOIC footprint.
