SN74LS240N Description

Short technical summary and product information.

The SN74LS240N is an octal buffer and line driver designed by On Semiconductor. This component features 3-state outputs, making it suitable for driving bus lines or buffering memory address registers. It is compatible with 3.3-V or 2.5-V logic inputs and offers PNP inputs that reduce DC loading.

 

Key electrical specifications include an operating voltage range of 4.75V to 5.25V and a maximum propagation delay of 15 ns at 5V. The device supports an output current of 15mA and 24mA. It operates within a temperature range of 0°C to 70°C.

 

Packaged in a 20-PDIP format, the SN74LS240N is designed for through-hole mounting. Its logic type is a buffer, inverting, with 4 bits per element and 2 elements per device. This makes it a versatile component for applications requiring signal buffering and driving in digital systems.

 

Applications for the SN74LS240N include servers, LED displays, network switches, telecom infrastructure, motor drivers, and I/O expanders. Its robust design and features contribute to improved performance and density in bus-oriented systems.
