SN74F280BNSR

Overview

The SN74F280BNSR is a nine-bit odd/even parity generator and checker from the Texas Instruments SN74F series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 10 ns. The device provides a high-level output current of -1 mA and a low-level output current of 20 mA. It is housed in a 14-pin SOIC package and supports surface-mount installation. The component functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Performs simultaneous generation and checking of odd or even parity for nine-bit data inputs
• Provides distinct outputs indicating correct parity, incorrect parity, or no valid parity condition
• Utilizes Schottky-clamped bipolar logic technology for enhanced switching speed

Applications

• Data transmission systems requiring real-time error detection
• Memory modules utilizing parity-based integrity verification
• Digital communication interfaces implementing standard parity protocols

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity. Confirm RoHS compliance status and environmental certifications prior to finalizing acquisition orders.

Selection Notes

Select this component when designing circuits requiring dedicated nine-bit parity processing capabilities. Consider the SN74F series performance profile regarding speed and power consumption relative to system requirements. Evaluate the SOIC-14 package dimensions for adequate PCB space allocation and thermal management during integration.

Part Context

This part belongs to the SN74F family of high-speed Schottky logic integrated circuits manufactured by Texas Instruments.
