CD74ACT541EE4

Overview

The CD74ACT541EE4 is an octal buffer and line driver manufactured by Texas Instruments. It utilizes the ACT logic series, which employs SCR-latchup-resistant CMOS technology to provide performance comparable to bipolar FAST/AS devices with significantly reduced power consumption. The device features non-inverting outputs and operates within a supply voltage range of 4.5 V to 5.5 V. It supports an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Provides balanced propagation delays for signal integrity
• Features ±24 mA output drive current capability
• Includes two active-LOW output enables for control

Applications

• Driving 50-ohm transmission lines
• Fanout expansion to FAST ICs
• Octal data buffering in digital systems

Procurement Notes

Verify the specific package type and lead finish configuration against the orderable part number CD74ACT541EE4. Confirm that the component meets RoHS compliance standards and matches the required operating temperature range for the intended application environment before finalizing procurement.

Selection Notes

Select this component when high-speed buffering with low power consumption is required. The ACT series offers superior speed compared to standard AC types while maintaining CMOS efficiency. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage requirement and utilizes appropriate bypass capacitors near the VCC terminals.

Part Context

This part belongs to the CD54/74AC540, -541, and CD54/74ACT540, -541 family of octal buffers and line drivers. These devices share common architectural features but differ in electrical characteristics such as speed and voltage ranges. The CD74 variant represents the commercial grade version of this logic family.

Replacement Considerations

CD74ACT541E serves as a direct equivalent within the same product family.
