TC74ACT240FT,TC74ACT244FT CMOS Digital Integrated Circuits Silicon Monolithic TC74ACT240FT,TC74ACT244FT 1. Functional Description • Octal Bus Buffer TC74ACT240FT: INVERTED, 3-STATE OUTPUTS TC74ACT244FT: NON-INVERTED, 3-STATE OUTPUTS 2. General The TC74ACT240FT and TC74ACT244FT 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. The TC74ACT240FT is an inverting 3-state buffer while the TC74ACT244FT is non-inverting. Both devices have two active-low output enables. These devices are designed to be used in such applications as 3-state memory address drivers. All inputs are equipped with protection circuits against static discharge or transient excess voltage. 3.

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 1: 180 mW in the range of Ta = -40 to 85 �. From Ta = 85 to 125 � a derating factor of -3.25 mW/� shall be applied until 50 mW. 10.
