TC74VHC32F/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC32F, TC74VHC32FT, TC74VHC32FK Quad 2-Input OR Gate TC74VHC32F The TC74VHC32 is an advanced high speed CMOS 2-INPUT 2 OR GATE fabricated with silicon gate C MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The internal circuit is composed of 4 stages including buffer output, which provide high noise immunity and stable output. An input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. TC74VHC32FT 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. Features High speed: t = 3.8 ns (typ.) at V = 5 V pd CC Low power dissipation: I = 2 A (max) at Ta = 25C CC High noise immunity: V = V = 28% V (min) NIH NIL CC TC74VHC32FK Power down protection is provided on all inputs. Balanced propagation delays: t t pLH pHL Wide operating voltage range: V = 2 V to 5.5 V CC (opr) Low noise: V = 0.8 V (max) OLP Pin and function compatible with 74ALS32 Weight SOP14-P-300-1.27A : 0.18 g (typ.)

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). 2 2014-03-01
