Texas Instruments SN74HC240N Octal Buffer Line Driver DIP 20, 2V to 6V

The Texas Instruments SN74HC240N is an octal buffer and line driver engineered to boost both performance and density in 3-state memory address drivers, clock drivers, bus-oriented receivers, and transmitters. This versatile IC is organised as two independent 4-bit buffers/drivers, each with its own output-enable (OE) input, giving you precise control over data flow in your digital circuits.

When the OE input is low, the device passes inverted data from the A inputs to the Y outputs, ensuring reliable signal inversion. When OE is high, the outputs enter a high-impedance state, allowing for bus sharing and multiplexing. With high-current outputs capable of driving up to 15 LSTTL loads, this buffer is ideal for demanding applications where signal integrity is critical.

Operating from a supply voltage range of 2V to 6V, the SN74HC240N delivers excellent flexibility for both low-power and standard logic systems. Enjoy minimal power consumption at just 80µA maximum, fast propagation delays of typically 9ns, and robust output drive capability of ±6mA at 5V. The device also features a low maximum input current of 1µA, reducing loading on preceding stages.

Presented in a reliable 20-pin DIP package, this IC is easy to integrate into through-hole circuit boards, making it suitable for prototyping, industrial control systems, and various digital logic applications. Whether you’re designing memory interfaces, clock distribution networks, or bus communication systems, the SN74HC240N provides the performance and reliability you need.
