SN74AS280NS

Overview

The SN74AS280NS is a parity generator and checker integrated circuit manufactured by Texas Instruments. It belongs to the AS logic series, utilizing bipolar technology. The device supports 9-bit data processing with complementary outputs for odd and even parity generation or checking. It operates within a supply voltage range of 4.5 V to 5.5 V and functions at temperatures from 0°C to +70°C. The component is housed in a 14-pin SOIC package.

Feature Summary

• Generates and checks 9-bit parity with complementary outputs
• Ultra-high speed performance characteristic of the AS logic family

Applications

• Data transmission error detection systems
• Memory unit parity verification
• Digital communication interface circuits

Procurement Notes

Verify the specific suffix 'NS' against the manufacturer's official datasheet to confirm the package type and temperature rating. Ensure compatibility with existing 5V logic levels and check for RoHS compliance status as required by project specifications before procurement.

Selection Notes

Select this component when high-speed parity processing is required for 9-bit data streams. The AS series offers superior speed compared to standard LS or ALS families. Confirm that the SOIC package fits the available PCB footprint and that the operating environment remains within the commercial temperature range.

Part Context

This part is part of the Texas Instruments 74AS logic family, known for high-speed operation using Schottky-clamped transistors. It serves as a functional equivalent to other parity generators but provides faster switching speeds suitable for high-frequency digital applications requiring reliable data integrity checks.
