74HC541DB,112

Overview

The 74HC541DB,112 is an octal buffer and line driver manufactured by Nexperia USA Inc. It belongs to the 74HC series of high-speed CMOS logic devices. The component features eight non-inverting outputs with three-state capability, allowing for effective bus-oriented connections. It operates within a supply voltage range of 2V to 6V. The device is housed in a 20-pin SSOP package. Key electrical characteristics include a low-level output current of 7.8mA and a high-level output current of -7.8mA. The propagation delay is specified at 13ns when operating at 6V with a 50pF load.

Feature Summary

• Provides eight non-inverting buffered outputs suitable for driving buses or loads.
• Features three-state control to isolate the bus during inactive periods.
• Operates across a wide supply voltage range from 2V to 6V.

Applications

• Bus-oriented systems requiring signal buffering
• Memory address drivers
• Clock distribution circuits

Procurement Notes

Verify the specific package variant, as the DB suffix indicates SSOP-20. Confirm availability status directly with authorized distributors, as lifecycle changes may affect production. Ensure compliance with RoHS and REACH regulations required for your region. Check for any recent Product Change Notifications regarding marking or assembly updates before finalizing procurement plans.

Selection Notes

Select this component when an octal buffer with three-state functionality is required for 2V to 6V logic systems. Compare against the 74HC541PW variant if TSSOP packaging is preferred over SSOP. Consider the 74HCT541 if strict 5V TTL compatibility is necessary instead of the broader HC voltage range. Evaluate pinout compatibility with existing PCB footprints.

Part Context

This part is part of the widely used 74HC family of CMOS logic integrated circuits. It serves as a standard solution for digital signal buffering in consumer electronics and industrial equipment. The manufacturer provides ECAD models and datasheets to support design integration. It is distinct from the HCT and VHC variants which offer different speed and voltage characteristics.

Replacement Considerations

The 74HC541PW,118 is a documented alternative offering identical logical function in a TSSOP-20 package. Verify that the physical footprint difference between SSOP and TSSOP does not impact the mechanical design before substitution.
