74ABT2541CMTCX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2541CMTCX is an octal buffer and line driver designed for driving capacitive inputs of MOS memory drivers, address drivers, clock drivers, and bus-oriented transmitters/receivers. It features integrated 25/58 series resistors in the outputs to reduce ringing and eliminate external components. The device operates within a supply voltage range of 4.5V to 5.5V. Key electrical characteristics include a maximum propagation delay of 3.6ns at 50pF load and 11.0ns at 250pF load. It provides high impedance glitch-free bus loading during power-up and power-down cycles.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation to ensure authenticity. Confirm that the ordering suffix matches the required tape and reel configuration if applicable. Check for RoHS compliance status as indicated in the datasheet revision history. Ensure the component meets the specified ambient temperature operating range for your application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving high-capacitance loads such as memory buses or clock networks where signal integrity is critical. The built-in series resistors simplify PCB layout by reducing the need for external termination components. Consider the guaranteed skew specifications for applications requiring tight synchronization between multiple output lines. Verify that the 5V logic family aligns with the rest of the system architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the ABT logic family, which combines the speed of Advanced Bipolar technology with the low power consumption of CMOS. It is functionally identical to the ABT541 but includes internal series resistors for enhanced performance in high-speed digital systems. The TSSOP-20 package offers a compact footprint suitable for space-constrained designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The ABT541 is functionally identical but lacks the internal series resistors. Verify if external resistors are required for the replacement to maintain signal integrity. Ensure the replacement device supports the same 4.5V to 5.5V supply voltage range and package dimensions.
