CD74HC283MT

Specialty Logic Overview

The CD74HC283MT 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 exhibits propagation delays ranging from 27 ns to 39 ns, with low-level and high-level output currents specified at 5.2 mA and -5.2 mA respectively. 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

• Implements 4-bit binary full addition with integrated fast carry functionality for efficient cascading.

Specialty Logic Applications
