Overview
The CD74HC541SM is an octal buffer and line driver manufactured by Harris Corporation, belonging to the HC logic family. It features non-inverting outputs with three-state capability controlled by dual active-low output enable inputs (OE1 and OE2). The device operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -55°C to +125°C. It utilizes a 20-pin SOIC package.
Feature Summary
- Octal buffer architecture providing eight independent non-inverting channels
- Three-state output control via dual active-low enable inputs for bus driving applications
- Wide supply voltage operation supporting 2V to 6V ranges
- Extended industrial temperature rating covering -55°C to +125°C
Applications
- Bus-oriented memory and signal switching
- Clock drivers and buffer circuits
- High noise immunity environments requiring three-state isolation
Procurement Notes
Verify the manufacturer designation as Harris Corporation, noting that this component may also be associated with Texas Instruments under similar part numbers. Confirm the specific suffix 'SM' corresponds to the SOIC-20 package variant. Ensure the datasheet matches the HC logic family specifications rather than HCT variants. Cross-reference RoHS compliance status if required for modern assembly processes.
Selection Notes
Select this component when an octal non-inverting buffer with three-state outputs is required for high-speed CMOS applications. It is suitable for designs needing wide voltage flexibility between 2V and 6V. Consider the extended temperature range for harsh environments. Verify pin compatibility with existing PCB layouts designed for standard 20-pin SOIC footprints.
Part Context
This component belongs to the 74HC series of high-speed CMOS logic devices. It serves as a non-inverting counterpart to the inverting 74HC540 buffer. The device is designed to drive up to 15 LSTTL loads while maintaining low power consumption typical of CMOS technology. It provides balanced propagation delays and transition times for reliable data transmission.
Replacement Considerations
Compatible substitutes include CD74HC541M and CD74HC541E from Texas Instruments. Other manufacturers offering equivalent HC-series octal buffers with three-state outputs should be verified for pinout and electrical parameter alignment.
