SN74AHC540DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AHC540DW is an octal buffer and driver with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and utilizes CMOS technology. The device features inputs and outputs on opposite sides of the package to facilitate printed circuit board layout. It includes two active-low output enable inputs (OE1 and OE2) that control the high-impedance state. The component provides inverted data when enabled and is designed for driving bus lines or buffering memory address registers.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features inputs and outputs positioned on opposite sides of the package to simplify printed circuit board routing.
• Provides three-state outputs controlled by two active-low output enable inputs.
• Accepts input voltages up to 5.5 V, allowing for down translation to lower VCC levels.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm status and packaging details. Confirm RoHS compliance and lead finish specifications before procurement. Ensure the selected variant matches the required operating temperature range and package dimensions for the target application design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring wide voltage operation between 2 V and 5.5 V. Consider the low drive characteristics to minimize output ringing on bus interfaces. Verify that the SOIC-20 package dimensions fit the available PCB space. Ensure unused inputs are tied to VCC or GND to prevent undefined operational states.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4AHC540 family of octal buffers/drivers. It is distinct from other logic families such as ALS, ABT, HCT, and HC due to its specific AHC technology and voltage range. The DW suffix indicates the SOIC package type. Other variants in the family include different package options like DB, PW, and N.
