SN74F280BNS

Overview

The SN74F280BNS is a single-circuit parity generator and checker from the Texas Instruments SN74F series. It features nine data inputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a 14-pin SOIC package for surface-mount installation. Electrical characteristics include a propagation delay of 10 ns, a high-level output current of -1 mA, and a low-level output current of 20 mA. It functions reliably across an operating temperature range from 0 °C to +70 °C.

Feature Summary

• Performs odd or even parity generation and checking on nine-bit data streams
• Provides complementary outputs indicating parity status

Applications

• Data transmission error detection circuits
• Memory system parity verification
• Digital communication interface integrity checks

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and electrical specifications. Ensure the selected variant matches the required package type and operating temperature range for the target application environment.

Selection Notes

Select this component when nine-bit parity processing is required in high-speed logic applications. Consider the F-series speed and drive capabilities alongside the SOIC package constraints. Validate input voltage levels against TTL standards to ensure proper logic threshold compliance.
