CY74FCT2541TQCTE4

Buffers, Drivers, Receivers, Transceivers Overview

The CY74FCT2541TQCTE4 is an octal line and MOS driver featuring three-state outputs, manufactured by Texas Instruments. It belongs to the FCT logic series and utilizes CMOS technology. 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, with a typical operating supply current of 3.3 mA. Propagation delay is 8 ns at 5 V. It is housed in a QSOP-20 package and supports surface mount installation.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides non-inverting buffering for eight input lines with simultaneous driving capability for connected loads.
• Features three-state outputs that allow isolation of the bus when not actively selected.
• Designed for high-speed signal transmission with defined propagation delay characteristics.

Buffers, Drivers, Receivers, Transceivers Applications

• High-performance memory mapping systems
• Clock drivers and buffer circuits
• Control line buffering in industrial environments

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance and RoHS status against the manufacturer's latest documentation. Confirm the QSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your system's thermal design constraints before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for 5V logic applications. Compare the 8 ns propagation delay against faster AC or ACT series alternatives if higher speed is needed. Verify that the 15 mA source and 12 mA sink currents are sufficient for the intended load capacitance and trace lengths.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the CY74FCT2541T family of octal buffers. It serves as a unidirectional driver variant within the broader FCT logic portfolio. The device complements bidirectional transceivers like the 245 series by providing dedicated output drive capabilities for bus structures requiring strict directionality.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

CY74FCT2541CTSOC offers similar functionality in an SOIC-20 package with a faster 4.1 ns propagation delay. CY74FCT541ATQCT provides equivalent logical operations in a 20-SSOP package.
