TC74LCX02F/FN/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX02F,TC74LCX02FN,TC74LCX02FT,TC74LCX02FK Low-Voltage Quad 2-Input NOR Gate with 5-V Tolerant Inputs and Outputs Note: xxxFN (JEDEC SOP) is not available in Japan. The TC74LCX02 is a high-performance CMOS 2-input NOR gate. TC74LCX02F Designed for use in 3.3-V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) V applications, CC but it could be used to interface to 5-V supply environment for inputs. All inputs are equipped with protection circuits against static discharge. Features Low-voltage operation: V = 1.65 to 3.6 V CC TC74LCX02FN High-speed operation: t = 5.2 ns (max) (V = 3.0 to 3.6 V) pd CC Output current: I /I = 24 mA (min) (V = 3.0 V) OH OL CC Latch-up performance: 500 mA Available in JEDEC SOP, JEITA SOP, TSSOP and VSSOP(US) Power-down protection provided on all inputs and outputs Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 02 type TC74LCX02FT TC74LCX02FK 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). Note 2: V = 0 V CC Note 3: High or low state. I absolute maximum rating must be observed. OUT Note 4: V < GND, V > V OUT OUT CC 2 2011-03-04
