SN74F280BN

Overview

The SN74F280BN is a single-circuit parity generator and checker from the Texas Instruments SN74F series. It supports 9-bit odd/even parity generation and checking functions. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters 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 is housed in a PDIP-14 package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Performs 9-bit odd or even parity generation and checking operations
• Utilizes high-speed F-series logic technology for efficient signal processing
• Provides standard TTL-compatible input and output characteristics

Applications

• Data transmission systems requiring error detection
• Memory modules utilizing parity checking mechanisms
• Digital communication interfaces ensuring data integrity

Procurement Notes

Verify the specific suffix 'BN' against the manufacturer's official datasheet to confirm the PDIP-14 package type and commercial temperature rating. Ensure compatibility with existing PCB footprints and voltage levels before integration. Cross-reference ordering information directly with Texas Instruments documentation to avoid discrepancies in pinout or electrical specifications.

Selection Notes

Select this component when a dedicated 9-bit parity solution is required within the SN74F logic family. Consider the trade-off between the 10 ns propagation delay and power consumption relative to other logic families. Verify that the 20 mA low-level sink capability meets the load requirements of the connected circuitry without exceeding absolute maximum ratings.

Part Context

This part belongs to the SN74F280B series, which encompasses various packaging options for the same logical function. The SN74F280BN specifically denotes the through-hole DIP variant. It serves as a specialized logic IC within the broader category of parity generators, distinct from general-purpose gates or flip-flops found in other SN74xx series devices.

Replacement Considerations

SN74LS280 offers similar functionality but with slower speed and different drive characteristics. SN74S280 provides faster performance but higher power consumption. Verify pinout compatibility and electrical parameter alignment before substituting.
