74ABT541CSJX

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ABT541CSJX is an octal buffer and line driver featuring 3-STATE outputs, housed in a 20-Lead Small Outline Package (SOP). It operates within a supply voltage range of +4.5V to +5.5V and supports ambient temperatures from -40°C to +85°C. The device provides non-inverting buffering with guaranteed output skew and simultaneous switching specifications for both 50pF and 250pF loads. Key electrical characteristics include a maximum propagation delay of 3.6ns at 50pF load, high sink capability of 64mA, source capability of 32mA, and latchup protection exceeding 10V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'X' indicates tape and reel packaging as per datasheet documentation. Confirm RoHS compliance status through official manufacturer channels or material composition declarations. Ensure the SOP package variant matches the required PCB footprint dimensions. Cross-reference the component against current lifecycle status to confirm availability and production continuity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with high-speed performance under ABT logic standards. The flow-through pinout facilitates ease of PC board layout compared to broadside configurations. Evaluate the 3.6ns propagation delay limits against system timing requirements. Consider the 64mA sink capability for driving heavy capacitive loads up to 250pF without signal degradation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-speed CMOS logic devices originally developed by Fairchild Semiconductor. The 74ABT541 functions as an octal buffer/line driver, distinct from latches like the 74ABT373 or receivers like the 74ABT244. It utilizes a 20-pin SOP package, differentiating it from SOIC or TSSOP variants within the same logical family.
