SN74S182N

Specialty Logic Overview

The SN74S182N is a look-ahead carry generator from the Texas Instruments S logic family. It operates on a single supply voltage ranging from 4.75 V to 5.25 V and supports a functional operating temperature range of 0°C to +70°C. The device is housed in a 16-pin Dual In-Line Package (DIP) designed for through-hole mounting.

Specialty Logic Feature Summary

• Generates parallel carry signals using look-ahead logic to accelerate arithmetic operations
• Accepts group propagate and group generate inputs to facilitate cascading with other ALUs

Specialty Logic Applications

• High-speed arithmetic logic units requiring rapid carry propagation
• Cascaded multi-bit adder configurations
• Digital signal processing circuits utilizing fast carry chains

Specialty Logic Procurement Notes

Verify that the specific procurement lot matches the SN74S182N designation, as TI manufactures both commercial and military variants under the SN54/74S182 umbrella. Confirm the package type corresponds to the standard plastic DIP rather than ceramic or leadless carriers. Ensure the component meets the required commercial temperature specifications before finalizing the order.

Specialty Logic Selection Notes

Select this component when designing systems that require faster carry generation compared to ripple-carry architectures. The S logic series provides higher speed performance suitable for demanding digital applications. Verify that the system power supply remains within the specified 4.75 V to 5.25 V limits to ensure reliable operation.

Specialty Logic Part Context

This component belongs to the Texas Instruments SN54/74S182 family of look-ahead carry generators. These devices are engineered to work in conjunction with arithmetic logic units, such as the SN74S181, to significantly reduce the delay associated with carry signal propagation across multiple bits.
