CD74HCT540M96

Overview

The CD74HCT540M96 is a high-speed CMOS logic octal inverting buffer and line driver manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides eight bits per element with a single circuit configuration. It utilizes a 20-SOIC package with a width of 0.295 inches (7.50 mm). Key electrical parameters include a propagation delay of 30 ns at nominal voltage, maximum output currents of ±7.8 mA, and a maximum operating frequency of 25 MHz. The component supports an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Octal inverting buffer architecture providing eight independent signal paths for data transmission.
• Three-state output capability allowing direct connection to bus systems without external switches.
• High-speed CMOS technology ensuring low power consumption while maintaining fast switching speeds.
• Wide operating temperature range suitable for demanding industrial and commercial environments.

Applications

• Bus-oriented systems requiring isolated signal buffering
• Clock drivers for high-frequency digital circuits
• Memory module address and data line drivers
• General-purpose line driving in microprocessor interfaces

Procurement Notes

Verify the specific suffix M96 indicates tape and reel packaging when ordering. Confirm RoHS compliance status as specified in the official datasheet. Ensure the supplier provides the correct 20-SOIC footprint dimensions for PCB layout compatibility. Check for any recent product change notices regarding manufacturing location or material composition updates before finalizing procurement.

Selection Notes

Select this component when an octal inverting buffer with three-state control is required for bus applications. The HCT series ensures compatibility with standard TTL logic levels while offering CMOS noise immunity. Consider the 20-SOIC package size for space-constrained designs. Verify that the 4.5 V to 5.5 V supply range matches the system power rails. Evaluate the 30 ns propagation delay against the target clock speed requirements.

Part Context

This part belongs to the Texas Instruments CD74HCT family of high-speed CMOS logic devices. It is functionally equivalent to the SN74HCT540 but packaged in SOIC format. The device serves as a critical interface component between microprocessors and peripheral memory or I/O devices. It replaces older bipolar logic families with lower power consumption and higher integration density.
