CY74FCT541CTSOCTE4

Overview

The CY74FCT541CTSOCTE4 is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V. The device provides high drive capability with a high-level output current of -32 mA and a low-level output current of 64 mA. Propagation delay is specified at 4.1 ns at 5 V. It functions in non-inverting mode with eight input lines and eight output lines. The component supports surface mount installation in a 20-SOIC package. Operating temperature ranges from -40°C to +85°C, with static current of 200 nA and operating power current of 3.3 mA.

Feature Summary

• Octal buffering and line driving with three-state output control
• High drive strength supporting heavy capacitive loads
• Non-inverting logic polarity for signal integrity

Applications

• Clock buffering and distribution
• Memory address and data bus drivers
• Carry chain expansion in complex logic designs

Procurement Notes

Verify the suffix 'E4' indicates lead-free composition compliant with RoHS standards. Confirm the SOIC-20 package dimensions match PCB footprint requirements. Ensure the operating temperature range meets system environmental specifications. Cross-reference the manufacturer part number against official datasheets to validate electrical characteristics before integration.

Selection Notes

Select this component for applications requiring high-speed octal buffering with significant drive current capabilities. The FCT logic family offers CMOS compatibility with TTL-like speed. Consider the 20-SOIC package for surface mount assembly processes. Evaluate propagation delay constraints to ensure timing margins are sufficient for the target clock frequencies.
