TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74ACT02P, TC74ACT02F, TC74ACT02FT
Quad 2-Input NOR Gate
The TC74ACT02 is an advanced high speed CMOS 2-INPUT NOR GATE fabricated with silicon gate and double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation.
This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features
• High speed: tpd = 4.6 ns (typ.) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • Compatible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (min) • Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω transmission lines. • Balanced propagation delays: tpLH ∼− tpHL • Pin and function compatible with 74F02

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 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C should be applied up to 300 mW.
