TC74HC14AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC14AP, TC74HC14AF Hex Schmitt Inverter The TC74HC14A is a high speed CMOS SCHMITT 2 TC74HC14AP INVERTER fabricated with silicon gate C MOS 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% V hysteresis and with its schmitt trigger CC 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. TC74HC14AF Features High speed: t = 11 ns (typ.) at V = 5 V pd CC Low power dissipation: I = 1.0 A (max) at Ta = 25C CC High noise immunity: V = 1.1 V at V = 4.5 V H CC Output drive capability: 10 LSTTL loads Symmetrical output impedance: I = I = 4 mA (min) OH OL Balanced propagation delays: t t pLH pHL Wide operating voltage range: V (opr) = 2.0 to 6.0 V CC Weight Pin and function compatible with 74LS14 DIP14-P-300-2.54 : 0.96 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). 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.
