74HC283FPEL-E

Overview

The 74HC283FPEL-E is a 4-bit binary full adder manufactured by Renesas Electronics Corporation. It belongs to the HD/RD74HC series, which features high-speed CMOS technology compatible with standard TTL logic levels. The device performs parallel addition of two 4-bit binary words and includes a carry-in input for cascading applications. It operates within a specified voltage range typical for HC series devices and utilizes a plastic package configuration suitable for surface mount or through-hole assembly depending on the specific pinout variant.

Feature Summary

• Performs 4-bit binary addition with fast carry propagation
• Compatible with standard 5V drive bipolar general-purpose logic families
• Supports cascading for multi-bit arithmetic operations

Applications

• Digital arithmetic logic units
• Address calculation circuits
• Data processing systems requiring parallel addition

Procurement Notes

Verify the exact package type and pinout configuration against the official datasheet before procurement. Confirm RoHS compliance status as it may vary by production batch. Ensure the supplier provides genuine Renesas Electronics Corporation components to avoid counterfeit risks. Check for any specific handling requirements related to electrostatic discharge protection during storage and installation.

Selection Notes

Select this component when a dedicated 4-bit full adder with fast carry is required in digital designs. Consider the operating voltage range and power consumption characteristics relative to system constraints. Evaluate the package options available for the specific manufacturing process. Compare performance metrics such as propagation delay against alternative logic families if speed is critical.

Part Context

This part is part of the extensive HD/RD74HC series from Renesas, known for its long market presence and reliability.
