74AHCT541D,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT541D,112 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device accepts TTL-level inputs and provides balanced propagation delays with Schmitt-trigger action on all inputs. It includes two active LOW output enable inputs (OE0 and OE1) that force outputs into a high-impedance state when asserted HIGH. Inputs are overvoltage tolerant up to 5.5 V, facilitating use in mixed-voltage environments.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features two independent active LOW output enable inputs for precise control of the three-state outputs.
• Provides overvoltage tolerant inputs allowing safe operation in mixed voltage logic environments.
• Incorporates Schmitt-trigger action at all input pins to ensure tolerance against slow input rise and fall times.

Buffers, Drivers, Receivers, Transceivers Applications

• Translating signals between different voltage domains in mixed-voltage systems
• Driving bus lines requiring high noise immunity and controlled output states
• Buffering data paths where balanced propagation delay is required

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing TTL logic sources with CMOS destinations operating at 5 V. The AHCT series ensures compatibility with standard TTL input thresholds while maintaining CMOS output drive capabilities. Ensure the application requires the specific SO20 package form factor and verify that the 4.5 V to 5.5 V supply range aligns with the system power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHCT541 family of octal buffers. It shares functional characteristics with the 74AHC541 but differs in input threshold levels, specifically designed to accept TTL logic levels. The 'D' designation indicates the SO20 plastic small outline package, while ',118' typically denotes tape and reel packaging; however, datasheet specifics for the ',112' suffix should be confirmed via official Nexperia documentation.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include other manufacturers' 74AHCT541 variants in SOIC-20 packages. Verify that substitute parts maintain the same TTL input voltage thresholds and three-state output behavior to ensure circuit compatibility without redesign.
