CY74FCT2541TSOCE4

Overview

The CY74FCT2541TSOCE4 is an octal line driver and MOS driver manufactured by Texas Instruments, belonging to the FCT logic series. It features non-inverting polarity with three-state outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a high-level output current of -15 mA and a low-level output current of 12 mA. Static current consumption is specified at 200 nA, while operating power current is 3.3 mA. Propagation delay is 8 ns at 5 V. The component supports surface mount installation and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Octal configuration providing eight independent input-to-output channels for parallel data transmission.
• Three-state output capability allowing multiple drivers to share bus lines without interference.
• Non-inverting signal path ensuring output states directly correspond to input logic levels.

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Multiplexer and demultiplexer decoders

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance status as per manufacturer documentation. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's 5V logic standards. Check humidity sensitivity等级 (MSL) for proper storage and handling procedures during assembly.

Selection Notes

Select this component when an octal buffer with three-state control is required for 5V CMOS applications. The FCT series offers speed comparable to LS-TTL but with CMOS power consumption. Consider the 20-SOIC package for surface-mount designs requiring moderate pin density. Verify that the 8 ns propagation delay meets your timing constraints for the target application frequency.

Part Context

This part belongs to the CY74FCT2541T family of octal buffers. The base model CY74FCT2541T serves as the standard reference, with the 'SOCE4' suffix denoting the specific tape-and-reel packaging and environmental compliance attributes. It is functionally equivalent to other industry-standard octal bus drivers within the same voltage and speed class.

Replacement Considerations

Direct substitutes include the CY74FCT2541ATSOC and CY74FCT2541CTSOC from Texas Instruments, which share identical logical functionality and pinout configurations. Cross-vendor equivalents such as the 74FCT2541ATQ from other manufacturers may also be compatible if pin compatibility and electrical specifications are verified against the official datasheet.
