74ABT2541CMSAX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2541CMSAX is an octal buffer and line driver featuring integrated 25/58 series resistors in the outputs. It operates within a supply voltage range of 4.5V to 5.5V and utilizes a 20-lead Shrink Small Outline Package (SSOP). The device provides non-inverting logic with two active-low output enable inputs, ensuring glitch-free bus loading during power cycles.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated 25/58 series resistors reduce ringing and eliminate external resistor requirements
• Guaranteed latchup protection ensures robust operation under electrical stress
• High impedance glitch-free bus loading maintained throughout the entire power up and power down cycle
• Disable time is less than enable time to effectively avoid bus contention

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 component status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm that the SSOP package dimensions match the design footprint. Ensure the ordering code suffix 'X' corresponds to the required tape and reel packaging format specified by the manufacturer.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving high-capacitance loads such as MOS memory interfaces without requiring external series resistors. The ABT2541 is functionally identical to the ABT541 but includes internal damping resistors. Verify that the operating temperature range of -40°C to +85°C meets the environmental requirements of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT logic family, which combines the speed of the ABT series with CMOS technology. It serves as an octal buffer designed specifically for driving heavy capacitive loads found in memory and address bus architectures. The inclusion of internal resistors distinguishes it from standard buffers like the ABT541.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet states the device is functionally identical to the ABT541. Verify if the ABT541 variant is available as a direct substitute, noting the absence of internal series resistors in the alternative.
