N74F283N,602

Specialty Logic Overview

The N74F283N,602 is a 4-bit binary full adder with fast carry from the 74F series. It performs addition of two 4-bit binary words plus an incoming carry. The device features fast internal carry look-ahead and is cascadable in 4-bit increments. It operates on a supply voltage range of 4.5V to 5.5V. Typical propagation delay is 6.5ns at 5V. Total typical supply current is 40mA. It is housed in a 16-pin plastic DIP package (SOT38-4) with a commercial temperature range of 0°C to +70°C.

Specialty Logic Feature Summary

• Performs high-speed 4-bit binary addition using fast internal carry look-ahead logic.
• Supports cascading in 4-bit increments for multi-bit arithmetic operations.
• Compatible with both active-high positive logic and active-low negative logic operands.

Specialty Logic Applications

• Implementation of 3-bit or larger binary adders through cascading
• Construction of 5-input encoders where inputs are equally weighted
• Design of 5-input majority gates

Specialty Logic Procurement Notes

Verify component authenticity as this part may be obsolete. Confirm package marking matches the 16-pin DIP format. Check datasheet revisions for any parameter updates. Ensure operating conditions align with the specified 4.5V to 5.5V supply range. Validate that the supplier provides traceability documentation for legacy components.

Specialty Logic Selection Notes

Select this component when a dedicated 4-bit binary full adder with fast carry is required. It is suitable for designs needing cascadable arithmetic units. Consider the 74F series speed characteristics against power consumption requirements. Verify pin compatibility if replacing older Philips Semiconductors versions.

Specialty Logic Part Context

This component belongs to the 74F (FAST) logic family, known for high-speed performance. It is manufactured by NXP USA Inc., formerly Philips Semiconductors. The 'N' suffix indicates a 16-pin plastic dual in-line package. It serves as a fundamental building block for digital arithmetic circuits within standard TTL-compatible systems.

Specialty Logic Replacement Considerations

Equivalent parts include the N74F283D,602 in SOIC packaging. Other manufacturers offer compatible 74F283 devices. Verify pinout and electrical specifications match before substitution. Ensure the replacement supports the required 4.5V to 5.5V operating voltage range.
