TC74VHCT125,126AF/AFN/AFT/AFK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHCT125AF,TC74VHCT125AFN,TC74VHCT125AFT,TC74VHCT125AFK TC74VHCT126AF,TC74VHCT126AFN,TC74VHCT126AFT,TC74VHCT126AFK TC74VHCT125AF/AFN/AFT/AFK TC74VHCT126AF/AFN/AFT/AFK Quad Bus Buffer Quad Bus Buffer 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 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 3.3 V to 5 V system. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. There structure prevents device detsruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc. Note: VCC = 0 V Note: xxxFN (JEDEC SOP) is not available in Japan.

Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
