SN74LS240NS Description

Short technical summary and product information.

The SN74LS240NS is an octal buffer and line driver designed by Texas Instruments. This component features inverting, 3-state outputs, making it suitable for driving bus lines or buffering memory address registers. It operates within a supply voltage range of 4.75V to 5.25V and has an operating temperature range of 0°C to 70°C.

 

The device is available in a 20-SOIC surface mount package. Key electrical characteristics include an output current capability of 15mA and 24mA, and a maximum propagation delay of 15 ns at 5V. The inputs are tolerant down to 2V and compatible with 3.3V or 2.5V logic. PNP inputs help reduce DC loading, and hysteresis at the inputs improves noise margins.

 

This buffer is designed to improve performance and density in bus-oriented systems. Its 3-state outputs allow for efficient bus management. The high fan-out and improved fan-in characteristics make it a versatile component for various digital logic applications.
