Key Features
- Hex 3-state bus driver with enable-low active control for easy bus sharing
- 24mA output sink current (IOL) for driving standard TTL and CMOS loads
- 45pF load capacitance rating ensuring signal integrity at typical bus speeds
- LS-family logic compatible with standard 5V supply and TTL input thresholds
- 16-pin SOIC (R-PDSO-G16) package for compact PCB footprint
Applications
The SN74LS367AD is widely used in microprocessor and microcontroller bus expansion circuits where multiple devices share a common data or address bus. Its 3-state outputs allow the driver to be tri-stated when not selected, preventing bus conflicts in multi-master or multi-peripheral designs. Typical applications include memory interfacing, backplane bus drivers, and industrial control systems requiring reliable TTL-level signal buffering.

Frequently Asked Questions
What is the output current capability of the SN74LS367AD?
The SN74LS367AD can sink up to 24mA (IOL = 0.024A) per output, making it compatible with standard TTL and CMOS loads. This current drive capability ensures reliable signal levels when driving multiple inputs or bus lines in typical 5V digital systems.
How does the 3-state output of the SN74LS367AD work?
The SN74LS367AD uses an active-low enable control signal to switch its outputs between normal logic-high/logic-low states and a high-impedance (tri-state) mode. When the enable pin is deasserted (logic high), all six outputs float, allowing other devices to drive the shared bus without conflict.
What are common applications for the SN74LS367AD?
Common applications include microprocessor bus expansion, memory address and data buffering, backplane drivers, and industrial control interfaces. Its unidirectional hex 3-state structure is ideal for systems where a single source drives multiple loads on a shared bus, such as 8-bit or 16-bit data bus architectures.
What package does the SN74LS367AD use and what are alternatives?
The SN74LS367AD is housed in a 16-pin SOIC package (JESD-30 code R-PDSO-G16), suitable for surface-mount assembly. Pin-compatible and functionally equivalent alternatives include the SN74LS367AN (DIP-16 through-hole) and other 74LS367 variants from manufacturers such as Nexperia and ON Semiconductor.
