CD74ACT283M

Specialty Logic Overview

The CD74ACT283M is a high-speed CMOS logic device belonging to the Texas Instruments 74ACT series. It functions as a 4-bit binary full adder with fast carry capabilities, designed for arithmetic operations in digital circuits. The component operates within a supply voltage range of 1.5V to 5.5V and supports an extended industrial temperature range from -55°C to +125°C. It is housed in a 16-pin SOIC surface-mount package. This integrated circuit provides efficient parallel addition for two 4-bit binary numbers.

Specialty Logic Feature Summary

• Implements 4-bit binary full addition with internal fast carry logic to minimize propagation delay during cascaded operations.
• Utilizes advanced CMOS technology compatible with standard TTL input levels across the specified operating voltage range.
• Engineered for wide thermal stability, ensuring reliable performance in harsh industrial environments.

Specialty Logic Applications

• Digital arithmetic processing units requiring parallel addition
• Industrial control systems operating under extreme temperature conditions
• High-speed data processing circuits utilizing 74ACT logic families

Specialty Logic Procurement Notes

Verify current manufacturing status as this specific part number may be obsolete or subject to production changes. Confirm that the 16-SOIC package dimensions match your PCB footprint requirements. Ensure the 1.5V to 5.5V supply voltage aligns with your system design. Check for RoHS compliance documentation if required by your regulatory standards. Validate lead times due to potential discontinuation notices.

Specialty Logic Selection Notes

Select this component when a 4-bit adder with fast carry is needed within the 74ACT logic family. It is suitable for designs requiring operation down to 1.5V, unlike standard 5V-only variants. Consider the 16-SOIC package for surface-mount assembly constraints. Evaluate the -55°C to +125°C temperature rating against your environmental specifications. Compare propagation delays with other 74AC/ACT devices for timing compatibility.

Specialty Logic Part Context

This device is part of the broader 74ACT series of high-speed CMOS logic ICs manufactured by Texas Instruments. The 74ACT family bridges the performance gap between standard HC/HCT logic and faster AC/AHCT technologies. It shares functional pinouts with other 74-series adders but offers distinct electrical characteristics tailored for low-voltage and high-speed applications.
