TC74AC280P

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

The TC74AC280P is an advanced high speed CMOS 9-BIT PARITY GENERATOR 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.

The TC74AC280P is composed of nine data inputs (A thru I) and odd/even parity outputs( ODD and EVEN).
The odd parity output is high when an odd number of data inputs are high. The even parity output is high when an even number of data inputs are high.

The word-length capability is easily expanded by cascading.
All TC74AC280P inputs are equipped with protection circuits against static discharge or transient excess voltage.
