TC74HC14AP/AF/AFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC14AP,TC74HC14AF,TC74HC14AFN Hex Schmitt Inverter The TC74HC14A is a high speed CMOS SCHMITT INVERTER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Pin configuration and function are the same as the TC74HC04A but the inputs have 25% VCC hysteresis and with its schmitt trigger function, the TC74HC14A can be used as a line receivers which will receive slow input signals. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Note: xxxAFN (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). 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 applied until 300 mW.
