TC74HC32AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC32AP, TC74HC32AF Quad 2-Input OR Gate The TC74HC32A is a high speed CMOS 2-INPUT OR GATE 2 TC74HC32AP fabricated with silicon gate C MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The internal circuit is composed of 2 stages including buffer output, which provide high noise immunity and stable output. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

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). Note 2: 500 mW in the range of Ta = 40C to 65C. From Ta = 65C to 85C a derating factor of 10 mW/C shall be applied until 300 mW.
