Quad 2-Input OR Gate
The TC74HC32A is a high speed CMOS 2-INPUT OR GATE fabricated with silicon gate C2MOS 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.
Note: xxxAFN (JEDEC SOP) is not available in Japan. TC74HC32AP

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even destruction. 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 = −40°C~65°C. From Ta = 65°C to 85°C a derating factor of −10 mW/°C shall be www.DataSheet4U.com applied until 300 mW.

Note:
The operating ranges must be maintained to ensure the normal operation of the device. Unused inputs must be tied to either VCC or GND.
