SN74LVT240APWG4 Octal Buffer/Line Driver with 3-State Outputs

The SN74LVT240APWG4 is a high-performance, octal buffer/line driver designed by Texas Instruments to provide optimal solutions for high-speed signal transmission and buffering needs. This integrated circuit is part of the LVT family, which is characterized by its low-voltage operation and tolerance to mixed-voltage system environments.

Featuring eight non-inverting buffer/line drivers with 3-state outputs, the SN74LVT240APWG4 allows for bidirectional communication with bus-oriented systems. Each buffer has a separate output-enable (OE) input that, when high, puts the output in a high-impedance state. This is particularly useful when multiple drivers are connected to the same bus, enabling control over which device is actively driving the bus.

With its wide operating voltage range of 2.7V to 3.6V, this device supports the interface with 3.3V logic levels while maintaining 5V tolerant inputs, which allows for a flexible use in systems that interface with different logic levels. The SN74LVT240APWG4 also provides improved output drive capability, with the ability to source and sink up to 24mA at the outputs, making it suitable for driving heavy loads or for use in bus termination applications.

The device comes in a 20-pin TSSOP (Thin Shrink Small Outline Package) that offers a compact footprint for space-constrained applications. The SN74LVT240APWG4 is characterized for operation from -40°C to 85°C, ensuring reliable performance over a wide temperature range, making it suitable for industrial and commercial applications.

Key features of the SN74LVT240APWG4 include:

• Eight non-inverting buffers with 3-state outputs
• Wide operating voltage range (2.7V to 3.6V)
• 5V tolerant inputs for interfacing with different logic levels
• High-drive outputs (-24mA Ioh, 24mA Iol)
• Power-off disable outputs permit live insertion
• 20-pin TSSOP packaging for a compact footprint
• Temperature range of -40°C to 85°C for reliable operation

The Texas Instruments SN74LVT240APWG4 is an essential component for designers who require a reliable and versatile octal buffer/line driver for their digital systems. Whether used in bus-oriented systems, memory drivers, or as an interface between different logic levels, this device ensures robust performance and compatibility.
