TOSHIBA 74VHCT126AFT

The TC74VHCT125A/126A 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 TC74VHCT125A requires the 3 - state control input overline{G} to be set high to place the output into the high impedance state, whereas the TC74VHCT126A requires the control input G to be set low to place the output into high impedance. The input voltage are compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3V to 5V system. Input protection and output circuit ensure that 0 to 5.5V can be applied to the input and output*1 pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc.
