SN74F244DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F244DWR is an octal buffer and line driver manufactured by Texas Instruments. It belongs to the 74F logic series, utilizing Schottky-clamped transistor-transistor logic (TTL) technology for high-speed operation. The device features eight non-inverting buffers organized into two groups of four channels, each controlled by a separate output enable input. It operates within a supply voltage range of 4.5V to 5.5V. The outputs are three-state capable, allowing connection to shared bus lines while minimizing power consumption in the high-impedance state. The component is housed in a 20-pin Small Outline Integrated Circuit (SOIC) package with a wide body.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific datasheet revision corresponding to the manufacturing date code, as electrical characteristics such as propagation delay may vary slightly between production lots. Confirm that the SOIC-20 package dimensions match the target PCB footprint requirements. Ensure the operating environment remains within the specified commercial temperature range to maintain guaranteed switching speeds. Cross-reference the manufacturer's latest reliability data for long-term deployment considerations.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when system design demands faster switching speeds than standard HC or HCT logic families provide. The F-series offers superior performance for high-frequency applications but requires careful attention to power supply decoupling due to higher current spikes during switching. Consider thermal management if driving multiple loads simultaneously, as the Schottky technology generates more heat than CMOS alternatives under heavy switching conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the broader 74F family of high-speed logic devices introduced to address the speed limitations of earlier TTL standards. The 'DWR' suffix indicates a specific tape-and-reel packaging format suitable for automated surface-mount assembly processes. It serves as a critical interface component in legacy and mixed-signal designs where speed is prioritized over low power consumption, bridging high-speed digital cores with peripheral interfaces.
