74LS280FP-E

Overview

The Renesas Electronics Corporation HD74LS280FP-E is a 9-bit odd/even parity generator and checker belonging to the LS logic series. It is housed in a PDSO16 package with FP-16DA lead form, featuring 16 terminals. The device operates within a temperature range of -20 °C to +75 °C. It provides inverted outputs and utilizes standard input regulation. The component is RoHS compliant and designed for single-function parity operations.

Feature Summary

• Performs 9-bit odd and even parity generation and checking functions
• Features inverted output polarity for signal compatibility
• Utilizes Low-power Schottky (LS) technology for balanced performance

Applications

• Data transmission systems requiring error detection
• Digital communication interfaces
• Microprocessor-based system data integrity verification

Procurement Notes

Verify the manufacturer part number HD74LS280FP-E against official Renesas documentation to confirm the specific FP-16DA package variant. Ensure the operating temperature range of -20 °C to +75 °C aligns with the target application environment. Confirm RoHS compliance status and check for any specific ordering suffixes that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a 9-bit parity solution is required within the LS logic family constraints. The PDSO16 package offers surface-mount convenience compared to through-hole alternatives. Consider the inverted output characteristic during circuit design to ensure proper logic level interfacing with downstream components. Verify thermal requirements against the specified -20 °C to +75 °C operational window.

Part Context

This component is part of the broader 74LS280 family of parity generators/checkers produced by various manufacturers including Hitachi and Texas Instruments. The Renesas version specifically adopts the FP-16DA surface-mount package configuration. It serves as a digital logic integrated circuit designed for reliable parity calculation in standard TTL-compatible environments.

Replacement Considerations

Compatible substitutes include SN74LS280 from Texas Instruments and HD74LS280 from Hitachi/Renesas. Verify pin-to-pin compatibility and identical logical function before substitution. Ensure the replacement part supports the same PDSO16 or equivalent footprint if board space is constrained.
