CY74FCT541ATSOC

Overview

The CY74FCT541ATSOC is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features eight non-inverting inputs driving three-state outputs within a single functional unit. The device operates on a supply voltage ranging from 4.75 V to 5.25 V. It provides high drive capability with a low-level output current of 64 mA and a high-level output current of -32 mA. Propagation delay is specified at 4.1 ns at 5 V. The component functions within a temperature range of -40°C to +85°C and is housed in a 20-SOIC surface-mount package.

Feature Summary

• Octal buffering architecture providing eight independent signal paths for data transmission
• Three-state output configuration allowing direct connection to bus structures without external switches
• High-drive capability supporting significant capacitive loads through robust output stages

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Multiplexer switch control logic
• Data register input buffering

Procurement Notes

Verify the specific suffix 'A' indicates the commercial temperature grade (-40°C to +85°C) and 'SOC' denotes the 20-SOIC package variant. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the required package style and thermal rating before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring high-speed octal buffering with defined propagation delays. The FCT series offers CMOS compatibility while delivering faster switching speeds than standard LS logic. Consider the 20-SOIC footprint for PCB layout constraints and verify that the 5V supply rail aligns with the system's power distribution network requirements.

Part Context

This integrated circuit is part of the broader 74FCT family of high-speed CMOS logic devices produced by Texas Instruments. The 74FCT541T series specifically addresses applications needing multiple buffered outputs with tri-state functionality. It serves as a critical interface component between microprocessors and peripheral devices or memory arrays in digital communication systems.

Replacement Considerations

Cross-reference with CY74FCT541CTSOC for identical electrical specifications in the same SOIC-20 package. Verify pinout compatibility with CY74FCT541ATQCT if transitioning to a QSOP/SSOP form factor, noting potential differences in physical dimensions.
