SN74LVC244APWRG3

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244APWRG3 is an octal buffer and line driver featuring three-state outputs, designed for operation within a 1.65 V to 3.6 V supply voltage range. It comprises two independent four-bit buffers with separate output enable inputs. The device supports asynchronous communication between data buses and accepts input voltages up to 5.5 V, enabling mixed-mode system operations. It operates over a temperature range of -40°C to +85°C and is housed in a TSSOP-20 package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting buffered channels with independent control via dual output enable inputs
• Supports mixed-mode signal operations by accepting 5 V tolerant inputs while operating at lower supply voltages
• Includes Ioff circuitry to prevent excessive current draw during live insertion or partial power-down events

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous data bus buffering and driving applications
• Clock distribution and timing signal buffering
• Memory address and data bus drivers in embedded systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix G3 indicates lead-free and RoHS compliance status according to Texas Instruments documentation. Confirm the TSSOP-20 package dimensions and moisture sensitivity level requirements for your assembly process. Ensure the 1.65 V to 3.6 V operating range aligns with your target system voltage rails before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is required for low-voltage logic families. It is suitable for designs needing 5 V input tolerance with 3.3 V or 1.8 V core supplies. Consider the TSSOP-20 package for space-constrained surface-mount layouts requiring high channel density.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC244A family of octal buffers. It shares functional similarities with other LVC series devices but is distinct from LV or ABT variants due to its specific voltage range and CMOS technology. The 'G3' suffix typically denotes environmental compliance features such as lead-free construction.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include SN74LVC244APWR and SN74LVC244ADW, provided pin compatibility and electrical specifications match the design requirements. Verify that substitute packages maintain the same thermal and mechanical constraints.
