N74F283D,602

Specialty Logic Overview

The N74F283D,602 is a 4-bit binary full adder with fast carry from the 74F series. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of 0°C to +70°C. The device features a typical propagation delay of 6.5ns and a total supply current of 40mA. It utilizes a 16-pin plastic small outline package (SOIC) with a body width of 3.9mm.

Specialty Logic Feature Summary

• Performs high-speed 4-bit 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 adders by tying specific operand inputs low.
• Construction of 2-bit and 1-bit adder configurations via stage partitioning.
• Design of 5-input encoders where outputs present a binary number of true inputs.
• Creation of 5-input majority gates that activate when three or more inputs are true.

Specialty Logic Procurement Notes

Verify the component status as discontinued before procurement planning. Confirm the specific ordering suffix matches the required package type. Ensure compatibility with existing system voltage levels and thermal constraints during integration.

Specialty Logic Selection Notes

Select this component for applications requiring fast 4-bit binary addition without external carry logic. Consider the 74F series speed characteristics against power consumption requirements. Verify pin assignments match the schematic design for operand and sum outputs.
