The SN74LS240DW is an octal buffer and line driver from Texas Instruments, designed to enhance the performance and density of bus-oriented systems. This device features 8 channels of inverting buffers with 3-state outputs, making it suitable for driving bus lines or buffering memory address registers.
Key electrical characteristics include a supply voltage range of 4.75V to 5.25V, with output currents of 15mA and 24mA. The operating temperature range is from 0°C to 70°C. The buffer offers high speed with a maximum propagation delay of 15 ns at 5V and includes features like input clamp diodes, PNP inputs to reduce DC loading, and hysteresis at inputs for improved noise margins.
This component is available in a 20-SOIC surface mount package. Its inputs are tolerant down to 2V and compatible with 3.3V or 2.5V logic, providing flexibility in mixed-voltage systems. The 3-state outputs are crucial for bus interfacing, allowing multiple devices to share a common data line.
The SN74LS240DW is designed for applications requiring efficient buffering and signal driving in digital systems. Its robust design and specific features make it a reliable choice for various interface and control functions.
