74ABT2541CMTC

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ABT2541CMTC is an octal buffer and line driver featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 4.5V to 5.5V, supporting output currents of 32mA high and 15mA low. The device includes 25 Ohm series resistors in the outputs to minimize signal reflections. It functions reliably across an operating temperature range of -40°C to 85°C and is housed in a 20-TSSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer date code and lot traceability upon receipt. Confirm the component matches the 74ABT2541CMTC designation and 20-TSSOP package dimensions. Inspect leads for straightness and solderability. Ensure storage conditions comply with moisture sensitivity level requirements to prevent damage before reflow soldering.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with integrated termination resistors is required for high-speed digital interfaces. The ABT technology offers faster switching speeds compared to standard HC or HCT families. Ensure the system power supply remains strictly within the 4.5V to 5.5V range to maintain electrical specifications and reliability.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT family of advanced BiCMOS logic devices. It serves as a high-performance alternative to older bipolar or standard CMOS buffers. The CMTC suffix indicates the specific 20-TSSOP surface-mount package variant manufactured by Fairchild Semiconductor, now part of onsemi.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other 74ABT2541 variants from different manufacturers, such as those from NXP or Texas Instruments, provided they share the same pinout and electrical characteristics. Verify that any replacement maintains the 25 Ohm series resistor feature if signal reflection suppression is critical.
