CD74HC541PW

Overview

The CD74HC541PW is an octal buffer and line driver manufactured by Texas Instruments, belonging to the 74HC logic series. It features eight non-inverting inputs and outputs with three-state capability. The device operates within a supply voltage range of 2 V to 6 V. Key electrical parameters include a high-level output current of -7.8 mA and a low-level output current of 7.8 mA. Static current is specified at 8 uA, with a maximum operating temperature of +125°C and a minimum of -55°C. Propagation delay varies from 115 ns at 2 V to 20 ns at 6 V. It is housed in a 20-TSSOP package.

Feature Summary

• Octal configuration providing eight independent non-inverting signal paths for bus-oriented systems.
• Three-state outputs allow connection to shared data buses without interference when disabled.
• Dual active-low output enables provide flexible control over data transmission timing.

Applications

• Memory address drivers in computer systems
• Clock drivers for synchronous circuits
• Bus-oriented system interconnects

Procurement Notes

Verify the specific suffix 'PW' corresponds to the 20-TSSOP surface-mount package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure thermal management aligns with the specified -55°C to +125°C operating range for the intended application environment.

Selection Notes

Select this component when an octal, non-inverting buffer with three-state output control is required for CMOS or TTL compatible interfaces. The wide supply voltage range supports various logic families. Consider the TSSOP package constraints for PCB layout and ensure input compatibility with standard CMOS outputs or LSTTL via external pull-ups if necessary.

Part Context

This part belongs to the Texas Instruments 74HC541 family of high-speed CMOS logic devices. It serves as a direct replacement for older LS541 pinouts while offering improved speed and lower power consumption. The device is designed for general-purpose buffering and driving applications in digital electronics.

Replacement Considerations

Check for equivalent parts such as SN74HC541PWR or MC74HC541ADTR2G. Verify pinout compatibility and electrical specifications before substitution. Ensure the alternative device meets the same voltage and temperature requirements.
