The Toshiba TC74LCX126F, TC74LCX126FT and TC74LCX126FK are high-performance CMOS quad bus buffers designed for use in 3.3-V systems. They operate from 1.65 to 3.6 V, have 5-V tolerant inputs and outputs, and maintain CMOS low power dissipation.
The datasheet gives pin assignment, truth table, absolute maximum ratings, operating ranges, DC and AC characteristics, test circuits and waveforms, and package dimensions for the SOP14, TSSOP14 and VSSOP14 packages. The output is placed in high impedance by setting the 3-state control input (OE) high.
