SN74LVC540ADBR Description

Short technical summary and product information.

The SN74LVC540ADBR from Texas Instruments is an octal buffer/driver designed for 1.65V to 3.6V VCC operation. This device features 3-state outputs and is suitable for driving bus lines or buffering memory address registers.

 

Key electrical characteristics include an operating voltage range of 1.65V to 3.6V, with inputs capable of accepting voltages up to 5.5V. It offers a maximum propagation delay of 5.3ns at 3.3V and supports mixed-mode signal operation. The device has an IOL of 24mA and IOH of -24mA.

 

Packaged in a 20-SSOP (0.209", 5.30mm Width) surface mount configuration, the SN74LVC540ADBR is designed for efficient printed circuit board layout with inputs and outputs on opposite sides. It also includes features like partial power-down mode support and high ESD protection.

 

This buffer/driver is ideal for applications requiring high-speed signal buffering and level translation, particularly in systems with mixed voltage levels.
