74AHCT541PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT541PW,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 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. All inputs feature Schmitt-trigger action for noise immunity. The component is housed in a TSSOP20 package (SOT360-1) and supports operating temperatures from -40 °C to +125 °C.

• Mixed-voltage level translation between CMOS and TTL domains

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix ',112' against current Nexperia documentation to confirm packaging details such as reel size or tape width. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Confirm RoHS compliance status matches the latest product data sheet revision before finalizing orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 5V TTL logic with 5V CMOS systems requiring octal buffering. The AHCT series ensures compatibility with standard TTL input thresholds while maintaining CMOS low power dissipation characteristics. Verify that the required operating temperature range extends to +125 °C and that the TSSOP20 package fits the available PCB footprint constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC/AHCT family of high-speed CMOS logic devices. The 74AHCT variant specifically bridges the gap between advanced CMOS performance and legacy TTL compatibility. It serves as a standard solution for digital signal routing in industrial and consumer electronics where reliable octal data transmission is required.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include the 74AHCT541D (SO20 package) and 74AHCT541BQ (DHVQFN20 package). Cross-manufacturer equivalents such as the SN74AHCT541PW from Texas Instruments may be considered if pinout and electrical specifications match exactly.
