What are the key features of SN74ABT240ANE4?

  • Octal 8-channel inverting 3-state buffer enables high-drive bus interfaces with active-low enable for easy bus arbitration
  • ABT (Advanced BiCMOS Technology) family delivers fast switching speeds with low output voltage drop (VOL < 1V typical at 5V VCC)
  • 3-state outputs allow multiple devices to share a common bus without contention, ideal for multiplexed data bus architectures
  • 20-pin PDIP package provides through-hole mounting compatibility for prototyping, repair, and legacy industrial system designs

What is SN74ABT240ANE4 used for?

The SN74ABT240ANE4 is widely used as a data bus buffer and line driver in microprocessor systems, memory interfaces, and backplane bus applications where 8-bit parallel data needs to be buffered and driven with inversion. It is suitable for address/data bus expansion in embedded systems, industrial PLCs, and communication equipment. The active-low enable and 3-state output architecture make it ideal for bidirectional bus switching and multiplexed data path control.

Frequently Asked Questions

What is the SN74ABT240ANE4 and how many channels does it have?

The SN74ABT240ANE4 is an octal (8-channel) inverting buffer and line driver with 3-state outputs. It belongs to TI's ABT logic family and features active-low enable control, allowing all 8 outputs to be simultaneously enabled or placed in high-impedance state for bus sharing applications.

What logic family does the SN74ABT240ANE4 belong to and what are its electrical characteristics?

The SN74ABT240ANE4 belongs to the ABT (Advanced BiCMOS Technology) family, which offers fast propagation delays and high output drive capability. It operates at 5V VCC with a typical output low voltage (VOL) below 1V at room temperature, ensuring compatibility with TTL and CMOS logic systems.

What package does the SN74ABT240ANE4 use?

The SN74ABT240ANE4 is packaged in a 20-pin Plastic Dual In-Line Package (PDIP), designated JESD-30 code R-PDIP-T20. The through-hole PDIP package is ideal for prototyping with breadboards, sockets, and legacy PCB designs, and is widely supported by wave soldering assembly processes.

What does the inverting and 3-state output feature mean for bus applications?

The inverting outputs mean each input logic HIGH produces a LOW output and vice versa, providing signal inversion in a single device. The 3-state output feature allows the outputs to be placed in a high-impedance state when the enable pin is deasserted, letting multiple bus drivers share the same data bus lines without electrical conflicts.

Is the SN74ABT240ANE4 RoHS compliant and lead-free?

Yes, the SN74ABT240ANE4 carries a Pbfree code of Yes and a JESD-609 e4 designation, confirming it is fully RoHS compliant and manufactured with a lead-free solder-compatible process meeting current environmental standards for use in commercial and industrial electronics.
