74ABT2541CMTC

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT2541CMTC is an octal buffer and line driver featuring non-inverting outputs with integrated series resistors. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum toggle frequency of 100 MHz. The device provides high drive capability with output sink currents up to 275 mA and source currents up to 32 mA. Propagation delays are specified at 3.6 ns maximum for 50 pF loads and 8.5 ns for 250 pF loads. It utilizes a 20-lead Thin Shrink Small Outline Package (TSSOP) and functions identically to the ABT541.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component status as discontinued or obsolete through official manufacturer channels before procurement planning. Confirm that the specific TSSOP package variant matches the required footprint. Ensure compatibility with existing design constraints regarding the integrated output resistors, as these affect signal integrity characteristics compared to standard buffers.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving high-capacitance loads without requiring external termination resistors. The integrated resistors simplify PCB layout by reducing parasitic effects. Verify that the 4.5V to 5.5V operating range aligns with the target system voltage. Consider the 100 MHz toggle frequency limit for high-speed clock applications.
