SN74S280N3

Overview

The SN74S280N3 is a 9-bit odd/even parity generator/checker from the Texas Instruments S Series. It operates on a single 5 V supply and features complementary outputs for both odd and even parity states. The device utilizes Schottky TTL technology to achieve high-speed switching characteristics, making it suitable for applications requiring rapid data validation. It is housed in a standard 14-pin plastic dual in-line package (PDIP) designed for through-hole mounting.

Feature Summary

• Provides simultaneous generation and checking of odd and even parity across nine input bits
• Features complementary output signals indicating valid odd or even parity conditions
• Utilizes Schottky TTL architecture to deliver high-speed logic performance

Applications

• Data transmission systems requiring real-time error detection
• Memory modules utilizing parity-based integrity verification
• Digital communication interfaces validating data packet accuracy

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature rating. Confirm RoHS compliance status and lead finish specifications against current production data sheets. Ensure the component meets the necessary military or commercial standards if applicable to the design requirements.

Selection Notes

Select this component when high-speed parity processing is required within a digital system. The S Series offers faster propagation delays compared to standard or low-power variants. Verify that the 14-pin PDIP footprint aligns with the target printed circuit board layout and assembly capabilities.
