SN74F244NSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74F244NSR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the SN74F logic series. It features eight non-inverting buffers with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a low-level output current of 64 mA and a high-level output current of -15 mA. Propagation delay is specified at 7 ns, with an operating temperature range from 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer source and date code upon ordering, as component availability may vary. Confirm that the package type matches the required PCB footprint and that the operating temperature range meets the environmental specifications of the target application before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for high-speed digital interfaces. Ensure the system design accommodates the 4.5 V to 5.5 V supply voltage constraints and that the 7 ns propagation delay aligns with the timing requirements of the connected circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the standard SN74F logic family, known for fast switching speeds compared to earlier TTL standards. The 'NSR' suffix indicates a 20-lead Small Outline Integrated Circuit (SOIC) package with tape-and-reel packaging, suitable for automated surface-mount assembly processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative octal buffers such as the SN74ACT244 or SN74F125 only if electrical parameters and pin configurations are manually cross-referenced against official datasheets.
