74ABT2541CMSA

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2541CMSA is an octal buffer and line driver featuring integrated 25/Ω to 58/Ω series resistors in the outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum toggle frequency of 100 MHz. The device provides high-impedance glitch-free bus loading during power cycles and includes two active-low output enable inputs (OE1, OE2). It is housed in a 20-lead shrink small outline package (SSOP) with a wide operating temperature range from -40°C to +85°C.

• Disable time is less than enable time to prevent bus contention
• High impedance glitch-free bus loading throughout power up and down cycles

Buffers, Drivers, Receivers, Transceivers Applications

• Driving capacitive inputs of MOS memory drivers
• Address drivers for system buses
• Clock drivers for synchronous circuits
• Bus-oriented transmitters and receivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix against current manufacturer documentation to confirm package type and lead-free status. Confirm RoHS compliance details as specified in JEDEC J-STD-020B. Ensure the component meets the required ambient temperature and supply voltage specifications for your application environment before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving high-capacitance loads such as MOS memory or address lines without requiring external series resistors. It is suitable for applications needing guaranteed output skew and simultaneous switching noise control. Consider the SSOP package constraints and verify that the 4.5V to 5.5V supply range aligns with the system power architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the ABT logic family, designed for high-speed digital applications. It is functionally identical to the ABT541 but distinguishes itself by incorporating internal series resistors. This integration simplifies board layout by managing signal integrity directly within the IC, making it a specialized choice for high-density bus systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet states the device is functionally identical to the ABT541. Verify if other ABT-series buffers with similar pinouts and electrical characteristics are available from the manufacturer or third-party suppliers as direct replacements.
