SNJ54LS240J

The Texas Instruments SNJ54LS240J is an octal buffer and line driver designed for improved performance and density in three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. This device features 8 channels with 3-state outputs, capable of driving bus lines or buffer memory address registers.

Key electrical characteristics include a maximum propagation delay of 15 ns at 5 V and a wide operating temperature range from -55°C to 125°C. The inputs are tolerant down to 2 V, making them compatible with 3.3-V or 2.5-V logic. PNP inputs reduce DC loading, and hysteresis at the inputs improves noise margins. The device offers a high fan-out and improved fan-in, with a noise margin of 400 mV.

Available in various packages including CDIP, CFP, LCCC, SSOP, SOIC, PDIP, and SOP, the SNJ54LS240J is suitable for applications such as servers, LED displays, network switches, telecom infrastructure, motor drivers, and I/O expanders. Its design allows for selected combinations of inverting and non-inverting outputs, symmetrical active-low output-control inputs, and complementary output-control inputs.
