SN74AC244NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AC244NSR is an octal buffer and line driver manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to +85°C. The device utilizes a 20-pin Small Outline (SO) package with surface-mount installation. Key electrical characteristics include a maximum output current of 24mA for both high and low states. It belongs to the 74AC logic series and functions as a non-inverting buffer with two internal elements, each handling four bits.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix NSR confirms the tape-and-reel packaging format when sourcing components. Ensure the part number matches the exact SN74AC244NSR designation to guarantee compatibility with the intended 20-SOIC footprint. Cross-reference manufacturer documentation for any recent product change notices regarding pinout or electrical specifications before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed buffering with moderate drive strength. The AC series offers faster propagation delays compared to standard HC logic while maintaining CMOS power efficiency. Consider the 20-SO package dimensions for PCB layout constraints. Verify that the system's load capacitance remains within the specified limits to maintain signal integrity at the desired switching speeds.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the broader 74AC family of high-speed CMOS logic devices produced by Texas Instruments. It serves as a direct functional equivalent to other octal buffers within the industry-standard 74xx logic lineage. The device is designed to interface between different logic families or drive heavy capacitive loads in complex digital architectures.
