TC74ACT32P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT32P, TC74ACT32F, TC74ACT32FT Quad 2-Input OR Gate The TC74ACT32 is an advanced high speed CMOS 2-INPUT TC74ACT32P OR GATE fabricated with silicon gate and double-layer metal 2 wiring C MOS 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. TC74ACT32F Features High speed: t = 4.5 ns (typ.) at V = 5 V pd CC Low power dissipation: I = 4 A (max) at Ta = 25C CC Compatible with TTL outputs: V = 0.8 V (max) IL V = 2.0 V (min) IH Symmetrical output impedance: I = I = 24 mA (min) OH OL Capability of driving 50 TC74ACT32FT transmission lines. Balanced propagation delays: t t pLH pHL Pin and function compatible with 74F32 Weight DIP14-P-300-2.54 : 0.96 g (typ.) SOP14-P-300-1.27A : 0.18 g (typ.) TSSOP14-P-0044-0.65A : 0.06 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 = 40 to 65C. From Ta = 65 to 85C a derating factor of 10 mW/C should be applied up to 300 mW. 2 2014-03-01
