ON Semiconductor DM74LS240N Octal 3-STATE Buffer/Line Driver/Line Receiver

The DM74LS240N is a high-quality integrated circuit produced by ON Semiconductor, renowned for its reliability and performance in digital systems. This device is part of the 74LS logic family and is designed to be used as an octal buffer and line driver with 3-STATE outputs. It is particularly useful in applications where high drive and fast switching are required.

The DM74LS240N features eight buffers with three-state outputs in a single package, providing a compact and efficient solution for increasing the drive capability of digital signals. This allows the chip to interface with bus lines in a system where multiple peripherals may need to communicate over the same channel. When the output-enable (OE) input is high, the device's outputs are in a high-impedance state, which effectively disconnects the buffer from the bus, preventing any interference with other devices connected to it.

Constructed with bipolar technology, the DM74LS240N offers a robust performance with a typical power dissipation of 95 mW and a wide operating temperature range from 0°C to 70°C. It operates on a supply voltage of 4.75V to 5.25V, making it compatible with standard TTL power levels, and it can drive loads with up to 15 LSTTL loads.

The DM74LS240N is housed in a standard 20-pin DIP (Dual In-line Package), making it easy to integrate into a variety of circuit boards. Its pin configuration is industry-standard, which facilitates its use as a drop-in replacement for other similar buffers or line drivers.

Applications for the DM74LS240N are diverse, including but not limited to, memory address drivers, bus-oriented systems, and buffer memory address registers. Its ability to quickly switch between driving high-current outputs and being in a high-impedance state makes it an invaluable component for managing data flow in complex digital systems.

ON Semiconductor's commitment to manufacturing high-quality components ensures that the DM74LS240N is a reliable choice for designers and engineers looking for a dependable buffer/line driver for their digital applications.
