- Active-low enable control with unidirectional 8-bit bus driver architecture provides straightforward tri-state output management
- 64 mA maximum output low current (IOL) enables robust drive of heavily loaded bus lines including backplanes and memory interfaces
- Lead-free (Pb-free) 20-pin SOIC package (R-PDSO-G20) with 50 pF rated load capacitance for standard bus driving scenarios
Applications
The SN74LVT240ADGVRE4 is used in memory bus interfaces, microprocessor address and data bus buffering, and FPGA I/O expansion circuits requiring 2.5V or 3.3V LVT-compatible unidirectional bus driving. It is also employed in industrial controllers and embedded systems where multiple board-level data buses must be driven with sufficient current for reliable signal integrity across card edges and backplanes. Its tri-state capability makes it suitable for bus-sharing architectures where multiple drivers must coexist on the same data lines.

Frequently Asked Questions
What supply voltages does the SN74LVT240ADGVRE4 support?
The SN74LVT240ADGVRE4 operates in the LVT logic family and supports 2.5V and 3.3V supply voltages, making it compatible with modern low-voltage digital systems including FPGA platforms, microcontrollers, and mixed-voltage bus architectures.
What is the output drive current of the SN74LVT240ADGVRE4?
The SN74LVT240ADGVRE4 provides a maximum output low current (IOL) of 64 mA (0.064 A), which is sufficient to drive heavily loaded bus lines including backplane connections, memory data buses, and multi-load PCB traces with good signal integrity.
How is the SN74LVT240ADGVRE4 enabled or disabled?
The SN74LVT240ADGVRE4 uses an active-low enable control, meaning the outputs are active when the enable pin is pulled low and tri-stated when the enable is high, allowing easy bus sharing and output isolation in multi-driver bus topologies.
What package does the SN74LVT240ADGVRE4 come in and is it lead-free?
The SN74LVT240ADGVRE4 is housed in a 20-pin SOIC package (JESD-30 code R-PDSO-G20) and is lead-free (Pb-free code: Yes), making it compliant with RoHS environmental directives and suitable for modern green electronics manufacturing.
How many bits does the SN74LVT240ADGVRE4 buffer and in which direction?
The SN74LVT240ADGVRE4 is an 8-bit unidirectional bus driver, meaning it buffers 8 data lines in one fixed direction from input to output, which is ideal for address bus buffering and unidirectional data distribution in microprocessor-based systems.
