CD74ACT540MG4

Overview

The CD74ACT540MG4 is an octal inverting buffer and line driver manufactured by Texas Instruments. It belongs to the ACT logic series, utilizing CMOS technology. The device features eight independent channels with three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 20-pin TSSOP package designed for surface-mount applications. The component supports a wide operating temperature range from -55°C to +125°C and exhibits a propagation delay of approximately 8.2 ns at 5 V.

Feature Summary

• Provides high-speed signal buffering and line driving capabilities through octal configuration
• Features three-state outputs allowing direct connection to bus structures
• Supports operation across extended industrial and military temperature ranges

Applications

• High-speed data bus buffering systems
• Clock distribution networks
• Memory address and data line drivers

Procurement Notes

Verify the specific suffix MG4 corresponds to the 20-pin TSSOP package variant when sourcing. Confirm RoHS compliance status as manufacturing processes may evolve. Ensure the supplier provides valid traceability documentation for the Texas Instruments origin. Cross-reference the active status with current manufacturer announcements to avoid obsolete stock.

Selection Notes

Select this component for designs requiring fast switching speeds and low power consumption compared to standard TTL equivalents. The ACT series offers improved performance over HC variants while maintaining compatible pinouts. Consider the TSSOP package constraints regarding thermal dissipation and board space requirements during layout planning.

Part Context

This part is part of the CD74ACT family of high-speed CMOS logic devices. It serves as the inverting counterpart to the non-inverting CD74ACT541. Both share similar electrical characteristics but differ in logical polarity. The family is designed for applications demanding faster propagation delays than standard HCT or HC logic families provide.

Replacement Considerations

CD74ACT541M96 is a functional substitute offering identical electrical specifications but with non-inverting logic polarity instead of inverting.
