74AHC541D,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC541D,118 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 5.5 V. The device includes two active-low output enable inputs (OE0 and OE1) that control the high-impedance OFF-state. Inputs are overvoltage tolerant up to 5.5 V, allowing use in mixed-voltage environments. It utilizes CMOS technology for low power dissipation and features Schmitt-trigger action on all inputs for noise immunity.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal buffer/line driver with three-state outputs

• Overvoltage tolerant inputs up to 5.5 V
• Schmitt-trigger action on all inputs

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed voltage level translation
• Memory address drivers
• Clock distribution buffers
• Bus-oriented transmissions

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '118' corresponds to the SO20 (SOT163-1) package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure design accounts for the specified temperature range of -40 °C to +125 °C. Cross-reference pinout details against the SOT163-1 outline drawing to prevent layout errors during PCB assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring eight buffered channels with independent tri-state control. The wide supply voltage range supports both 3.3 V and 5 V logic systems. Overvoltage tolerance simplifies interfacing between different voltage domains without external level shifters. Verify input transition rates against recommended operating conditions to ensure signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other industry-standard octal bus transceivers but offers specific Nexperia packaging and reliability characteristics. The D suffix indicates the plastic small outline package (SO20), distinguishing it from TSSOP or QFN variants within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct equivalents such as the 74AHCT541D,118 if TTL-compatible input levels are required instead of CMOS levels. Verify pin compatibility before substituting with other manufacturers' octal buffers.
