PI74FCT541TSE

Buffers, Drivers, Receivers, Transceivers Overview

The PI74FCT541TSE is a Fast CMOS non-inverting octal buffer and line driver manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.75V to 5.25V, with typical quiescent current at 500μA. The device features TTL-compatible input and output levels, low ground bounce outputs, and hysteresis on all inputs. Propagation delay ranges from 1.5ns to 6.0ns depending on speed grade, with output enable times up to 9.5ns. It supports an industrial operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific speed grade suffix (e.g., A, C, D) against the datasheet ordering information to ensure correct propagation delay specifications. Confirm that the 'E' suffix indicates Pb-free and Green compliant packaging. Check for availability as this component may be subject to lifecycle changes or discontinuation status.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select the PI74FCT541TSE when a non-inverting octal buffer is required with physical pin grouping for dense layouts. Choose based on the necessary propagation delay performance by matching the speed grade suffix. Ensure the application requires TTL-level compatibility and operates within the specified industrial temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the PI74FCT244T/541T family of Fast CMOS Octal Buffer/Line Drivers. It shares functional similarities with the PI74FCT244T but differs in pin configuration, grouping inputs and outputs separately to facilitate easier PCB routing compared to interleaved pin arrangements found in other logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The PI74FCT244T offers similar driver capabilities but utilizes an interleaved pin configuration rather than the physically grouped layout of the 541T. Verify pinout compatibility before substitution to avoid board redesign requirements.
