SN74LV244ATRGYRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ATRGYRG4 is an octal buffer and line driver from Texas Instruments, featuring three-state outputs. It operates within a voltage range of 2V to 5.5V and supports mixed-mode operation allowing independent interfacing between different voltage domains. The device includes an Ioff feature that prevents excessive current draw when the part is powered down. It offers high-speed performance with propagation delays as low as 6.5ns at 5V. The component is housed in a 20-pin VQFN package (RGY) and is designed for improved density and performance in memory address drivers, clock drivers, and bus-oriented receivers.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'RGYR' corresponds to the VQFN-20 package and tape-and-reel quantity. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering information matches the exact electrical specifications required for your system design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-density octal buffering with flexible voltage compatibility. The LV series provides superior speed compared to standard logic while maintaining low power consumption. Consider the VQFN package size constraints and thermal dissipation needs when finalizing the layout.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV244A family of octal buffers. It is functionally similar to other LV series devices but optimized for specific packaging and reel configurations. The 'A' variant typically denotes updated manufacturing processes or enhanced reliability characteristics within the legacy 74LV lineage.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LV244APWR or SN74LV244ADW for pin-compatible alternatives in TSSOP or SOIC packages. Verify electrical parameters match if substituting with non-TI equivalents.
