74ABT16541CMTDX

Buffers, Drivers, Receivers, Transceivers Overview

The Fairchild Semiconductor 74ABT16541CMTDX 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 and supports output sink currents up to 64mA and source currents up to 32mA. The device is housed in a 48-lead Thin Shrink Small Outline Package (TSSOP) designed for surface mount applications. It functions as a high-performance bus transceiver suitable for memory and address driving.

• Clock signal distribution
• Bus-oriented transmitter and receiver circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor's logic division was acquired by onsemi. Confirm that the component matches the original Fairchild specifications rather than current onsemi revisions. Ensure the package marking and date code align with legacy production batches. Validate RoHS compliance status against the specific manufacturing lot documentation provided by the supplier.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a wide-voltage 5V operation is required for high-speed data transmission. The 48-pin TSSOP package offers a compact footprint for dense board layouts. Consider the 64mA sink capability for driving heavy capacitive loads or long traces without external buffering. Ensure the design accommodates the specific pinout configuration of the 48-lead shrink package.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of advanced BICMOS logic devices. These components are engineered for high-speed performance while maintaining compatibility with standard TTL and CMOS interfaces. The 74ABT16541 variant specifically provides eight independent buffers, making it a core building block for parallel data buses in computing and telecommunications systems.
