TC74VHC125,126F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC125F, TC74VHC125FK TC74VHC126F, TC74VHC126FK TC74VHC125F/FK TC74VHC126F/FK Quad Bus Buffer Quad Bus Buffer TC74VHC125F, TC74VHC126F The TC74VHC125/126 are high speed CMOS QUAD BUS BUFFERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Shottky TTL while maintaining the CMOS low power dissipation. The TC74VHC125 requires the 3-state control input G to be set high to place the output into the high impedance state, whereas the TC74VHC126 requires the control input G to be set low to place the output into high impedance. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.
