74ABT541DB,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT541DB,118 is an octal buffer and line driver manufactured by Nexperia (formerly Philips Semiconductors). It features BiCMOS technology providing high-speed performance with low power dissipation. The device includes three-state outputs capable of sinking 64mA and sourcing 32mA. It operates within a supply voltage range of 4.5V to 5.5V. Propagation delay is typically 2.9ns at 5V with a 50pF load. The component is housed in a 20-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal bus interface design for driving MOS microprocessor buses
• High output drive capability with strong sink and source currents
• Power-up state defaults to high-impedance three-state
• Input and output pins located on opposite sides of the package

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffering
• High-performance microprocessor systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin as the product was originally released under Philips Semiconductors before the transition to Nexperia. Confirm that the specific ordering suffix matches the required 20-pin SSOP Type II package configuration. Ensure compatibility with standard 5V logic levels and check for any RoHS compliance documentation relevant to the production batch.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high fan-out and fast propagation speeds are required for 5V logic applications. The wide output current capacity supports heavy capacitive loads typical in bus architectures. Consider the SSOP package dimensions for PCB layout constraints compared to SO or DIP alternatives within the same logic family.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-performance BiCMOS logic devices. It functions similarly to the 74ABT241 but provides non-inverting buffering. The series is designed to replace older TTL equivalents while offering superior speed and lower power consumption suitable for modern computing and industrial control environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes functional similarity to the 74ABT241. Verify pinout compatibility if substituting with other octal buffers from the 74ABT or 74ACT families.
