TC74ACT540,541P/F/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT540P,TC74ACT540F,TC74ACT540FT TC74ACT541P,TC74ACT541F,TC74ACT541FT Octal Bus Buffer TC74ACT540P/F/FT TC74ACT541P/F/FT Inverting, 3-State Outputs Non-Inverting, 3-State Outputs TC74ACT540P, TC74ACT541P The TC74ACT540/TC74ACT541 are advanced high speed CMOS OCTAL BUS BUFFERs fabricated with silicon gate and double-layer metal wiring C2MOS technology. They achieve the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. These devices 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. The TC74ACT540 is an inverting type, and the TC74ACT541 is a non-inverting type. When either G1 or G2 are high, the terminal outputs are in the high-impedance state. All inputs are equipped with protection circuits against static discharge or transient excess voltage.

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.
