74AHC541D,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC541D,112 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 and utilizes a SOIC-20 (SOT163-1) package. The device includes two active-low output enable inputs (OE0 and OE1). Inputs are overvoltage tolerant up to 5.5 V, allowing use in mixed-voltage environments. Static characteristics specify a maximum input leakage current of 2.0 μA at -40 °C to +125 °C and a maximum supply current of 80 μA under the same conditions.

• Driving bus lines with multiple receivers
• Providing memory address/data buffering

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '112' corresponds to the standard tape-and-reel packaging format required for automated assembly processes. Confirm that the SOIC-20 package dimensions align with the designated footprint on the target printed circuit board. Ensure the procurement channel provides documentation verifying compliance with relevant environmental directives applicable to the deployment region.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal non-inverting buffer with three-state capability is required. The AHC series offers CMOS-level input compatibility and wide voltage operation. Verify that the application does not require TTL-level input thresholds, which would necessitate the AHCT variant instead. Consider the thermal dissipation limits if operating near maximum ambient temperatures.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC family of high-speed CMOS logic devices manufactured by Nexperia. It shares functional similarities with other octal buffers in the series but is distinguished by its specific AHC speed and power characteristics. The D suffix indicates the plastic small outline package configuration, differentiating it from TSSOP or QFN variants within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT541D,112 serves as a direct functional replacement if TTL input thresholds are required instead of CMOS levels. Other manufacturers may offer equivalent octal buffers, but pinout and electrical specifications must be verified against the official datasheet before substitution.
