TC74AC280P/F/FN
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74AC280P,TC74AC280F,TC74AC280FN
9-Bit Parity Generator/Checker
Note: xxxFN (JEDEC SOP) is not available in
Japan.
The TC74AC280 is an advanced high speed CMOS 9-BIT
PARITY GENERATOR fabricated with silicon gate and
double-layer metal wiring C2MOS technology.
TC74AC280P
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The TC74AC280 is composed of nine data inputs (A thru I) and
odd/even parity outputs(Σ ODD and Σ 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.
TC74AC280F
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

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