SN74ABT244APWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT244APWG4 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the ABT logic series. It features eight non-inverting inputs and outputs with three-state capability, housed in a TSSOP-20 surface-mount package. The device operates within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum operating current of 250 uA. It supports high-level output currents of -32 mA and low-level output currents of 64 mA, ensuring robust drive capabilities. The component functions reliably across an extended temperature range from -40°C to +85°C, with a typical propagation delay of 4.3 ns.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Cross-reference the datasheet for exact pinout configurations to prevent installation errors during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state outputs is required for 5V logic applications. The ABT series offers a balance of speed and power efficiency compared to standard TTL or CMOS alternatives. Consider the TSSOP-20 package if space constraints favor surface-mount technology over through-hole options. Verify that the 4.5V to 5.5V supply range aligns with your system's power distribution network.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT244A family of octal buffers and line drivers. It is functionally compatible with other variants in the series, differing primarily in packaging such as SOIC or SSOP, and environmental compliance suffixes. The G4 suffix typically denotes lead-free manufacturing and RoHS compliance, distinguishing it from older non-compliant versions while maintaining identical electrical specifications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74ABT244APWR for standard packaging or SN74ABT244ADWE4 for SOIC packages. Ensure any replacement maintains the same ABT logic family characteristics and three-state functionality. Verify that thermal and mechanical constraints of alternative packages are acceptable for your design.
