Overview
The CD74HC540M is an octal inverting buffer and line driver manufactured by Texas Instruments. It belongs to the HC logic family and features three-state outputs for bus-oriented applications. The device operates within a supply voltage range of 2 V to 6 V. It provides high-level output current of -7.8 mA and low-level output current of 7.8 mA. The static current is typically 8 uA, with a maximum operating temperature of +125°C and a minimum of -55°C. It is housed in a 20-SOIC package.
Feature Summary
- Octal inverting buffer configuration with three-state outputs
- High-speed CMOS technology for efficient operation
- Wide operating voltage range suitable for various digital systems
Applications
- Bus-oriented memory and address drivers
- Clock drivers
- Buffering for microprocessor systems
Procurement Notes
Verify the specific suffix 'M' indicates the SOIC-20 package variant when ordering. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to procurement. Ensure the supplier provides genuine Texas Instruments components to guarantee performance specifications and reliability standards are met.
Selection Notes
Select this component for designs requiring octal buffering with inversion capabilities. The HC series offers compatibility with standard CMOS logic levels. Consider the 20-SOIC package for surface-mount assembly requirements. Verify that the 2V to 6V supply range aligns with the system's power architecture.
Part Context
This part is part of the CD74HC54x series, which includes both inverting (540) and non-inverting (541) variants. It serves as a key component in digital logic circuits where signal integrity and bus driving are critical. The device complements other Texas Instruments logic families designed for high-performance computing applications.
Replacement Considerations
CD74HC540M96: Verified alternative from Texas Instruments featuring the same logical function and pinout but packaged in tape-and-reel format for automated assembly.
