The SN74HC240DW from Texas Instruments is an active octal buffer and line driver designed for improved performance and density in bus-oriented applications. This device features two 4-bit buffers with separate output-enable (OE) inputs. When OE is low, it passes inverted data from the A inputs to the Y outputs. When OE is high, the outputs enter a high-impedance state.
Key electrical characteristics include a wide operating voltage range of 2V to 6V, high-current outputs capable of driving up to 15 LSTTL loads, and low power consumption with a maximum ICC of 80µA. The typical propagation delay is 9ns, with a speed range of 5-10ns. It also features a low input current of 1µA maximum.
Designed for applications requiring efficient buffering of memory address drivers, clock drivers, and bus transceivers, the SN74HC240DW is suitable for systems needing robust signal integrity and high-speed data transfer. Its 3-state outputs are ideal for driving bus lines or buffering memory address registers.
The SN74HC240DW is supplied in a 20-SOIC package, designed for surface mounting. The operating temperature range is -40°C to 125°C, making it suitable for a variety of environmental conditions.
