TC74AC283P/F/FN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74AC283P,TC74AC283F,TC74AC283FN 4-Bit Binary Full Adder The TC74AC283 is an advanced high speed CMOS 4-BIT BINARY FULL ADDER 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. Sum () outputs are provided for each bit and a resultant carry (C4) is obtained from the fourth bit. This adder features full internal look-ahead across all four bits. A4 x n bit binary adder is easily built up by cascading the AC283 without any additional logic. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Note: xxxFN (JEDEC SOP) is not available in Japan.

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 = -40~65C. From Ta = 65 to 85C a derating factor of -10 mW/C should be applied up to 300 mW.
