SN74ABT541BDWRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT541BDWRG4 is an octal buffer and line driver utilizing state-of-the-art EPIC-IIB BiCMOS technology. It features eight non-inverting inputs and outputs with three-state control, 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 an operating temperature from -40°C to +85°C. It provides high-drive outputs capable of sourcing -32 mA and sinking 64 mA, ensuring robust signal integrity for bus lines and memory address registers.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Utilizes EPIC-IIB BiCMOS design to significantly reduce power dissipation compared to standard technologies.
• Features high-impedance state during power-up and power-down to prevent bus contention.
• Includes two active-low output enable inputs (OE1, OE2) that force all outputs to a high-impedance state when asserted.
• Inputs and outputs are positioned on opposite sides of the package to facilitate printed circuit board layout.

Buffers, Drivers, Receivers, Transceivers Applications

• Driving bus lines in digital systems
• Buffering memory address registers
• High-speed data transmission interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the G4 suffix indicates RoHS compliance and lead-free manufacturing status as per Texas Instruments standards. Confirm the DW package designation corresponds to the Plastic Small-Outline package type. Ensure the ordering part number matches the specific reel quantity and moisture sensitivity level required for your assembly process.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high drive strength and low power consumption in a 5 V logic environment. The ABT series offers faster switching speeds than standard 74LS or 74HC families. Consider the SOIC-20 package dimensions for PCB footprint compatibility and thermal management requirements relative to other available packages like TSSOP or SSOP.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT541B family of octal buffers with 3-state outputs. It is manufactured by Texas Instruments using their proprietary EPIC-IIB BiCMOS process. The G4 suffix denotes environmental compliance, while the BDWR suffix specifies the SOIC package, tape and reel packaging, and production revision.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74ABT541BDWR is the direct predecessor without the G4 suffix. SN74ABT541BPWR offers the same functionality in a TSSOP-20 package. SN74ABT541BDBR provides equivalent performance in an SSOP-20 package. All share identical electrical characteristics and pinouts.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device behave during power-up?

The device enters a high-impedance state when VCC is between 0 and 2.1 V, preventing bus contention during power transitions.

What is the latch-up performance rating?

The latch-up performance exceeds 500 mA per JEDEC Standard JESD-17, ensuring reliability under transient conditions.
