SN74ABT541BDBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT541BDBR is an octal buffer and line driver utilizing Texas Instruments' EPIC-IIB BiCMOS technology. It features eight non-inverting inputs and outputs with three-state control, housed in a 20-pin SSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include high-drive outputs capable of -32 mA source and 64 mA sink currents. Propagation delays are specified at a maximum of 3.9 ns for A-to-Y transitions and 5.8 ns for OE-to-Y transitions under standard conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• EPIC-IIB BiCMOS design significantly reduces power dissipation compared to standard logic families.
• Outputs maintain a high-impedance state during power-up and power-down sequences to prevent bus contention.
• Inputs and outputs are positioned on opposite sides of the package to facilitate printed circuit board layout.

• Driving bus lines in digital systems
• Buffering memory address registers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the SSOP (DB) package type and production status. Confirm RoHS compliance and lead finish details via the latest Package Option Addendum. Ensure the operating temperature range matches the application requirements for the commercial grade variant.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high drive strength and low power consumption are required for octal data buses. The ABT series offers faster switching speeds than standard ALS or LVC families while maintaining lower power than older ABT variants. Verify that the 4.5 V to 5.5 V supply voltage aligns with the system power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT541B family of octal buffers/drivers. It shares functional compatibility with other members of the series but differs in packaging options such as SOIC, TSSOP, or DIP. The 'B' designation indicates the specific revision of the ABT logic family with improved performance characteristics.

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, ensuring outputs do not drive the bus during power transitions.

What is the latch-up performance rating?

The latch-up performance exceeds 500 mA per JEDEC Standard JESD-17.
