CD74HCT283MT

Specialty Logic Overview

The CD74HCT283MT is a high-speed CMOS logic device manufactured by Texas Instruments, functioning as a 4-bit binary full adder with fast carry. It operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 16-SOIC package. The component features propagation delays ranging from 27 ns to 39 ns, with low-level output current of 5.2 mA and high-level output current of -5.2 mA. It maintains a static current of 8 uA and functions reliably across an operating temperature range of -55°C to +125°C.

Specialty Logic Feature Summary

• Performs 4-bit binary addition with internal fast carry functionality for rapid ripple carry operations.
• Utilizes high-speed CMOS technology compatible with standard logic families.

Specialty Logic Applications

• Digital arithmetic processing circuits
• Data path accumulation units
• Address generation logic

Specialty Logic Procurement Notes

Verify the specific suffix 'MT' against the manufacturer's official datasheet to confirm package dimensions and tape-and-reel specifications. Confirm RoHS compliance status and check for any Product Change Notifications (PCN) regarding obsolescence or design changes. Ensure the ordering part number matches the exact pinout and electrical characteristics required for the target application.

Specialty Logic Selection Notes

Select this component when a 4-bit parallel adder with fast carry is required in a surface-mount design. Verify that the HCT input compatibility meets the driving logic levels. Compare propagation delay specifications against system timing requirements. Ensure the SOIC-16 package fits the available PCB footprint constraints.

Specialty Logic Part Context

This device belongs to the Texas Instruments CD74HC/HCT series of high-speed CMOS logic devices. It is part of the broader 74xx family of digital integrated circuits designed for general-purpose logic applications. The HC and HCT variants offer similar logical functionality but differ in input threshold voltages and drive capabilities.

Specialty Logic Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Consult the manufacturer's cross-reference guide for equivalent devices such as the CD74HC283MT or other 4-bit adders from the same family.
