SN74F280BD

Overview

The SN74F280BD is a single-circuit, 9-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 supports a propagation delay of 10 ns. The device features 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 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 data bits
• Provides complementary outputs indicating parity status

Applications

• Data transmission systems requiring error detection
• Memory modules utilizing parity checking
• Digital communication interfaces

Procurement Notes

Verify that the specific part number matches the required logic family and package type. Confirm RoHS compliance status through official manufacturer documentation before procurement. Ensure the component meets the necessary thermal and electrical specifications for the intended application environment.

Selection Notes

Select this component when a fast F-series parity function is required in a surface-mount package. Compare against LS or ALS variants if lower power consumption is prioritized over switching speed. Verify pin compatibility with existing PCB layouts designed for standard 14-pin SOIC footprints.

Part Context

This component belongs to the SN74F logic family, known for high-speed performance compared to standard TTL. It serves as a digital logic integrated circuit designed for parity verification tasks within larger system architectures.

Replacement Considerations

SN74F280N (PDIP-14) offers identical functionality in a through-hole package.
