What is SN74LS367ADG4 used for?
The SN74LS367ADG4 is widely used in legacy TTL microprocessor systems to buffer 6-bit address or data lines, providing signal isolation and drive-current amplification for bus loads at 5 V. It fits naturally in prototyping boards and through-hole-friendly SOIC assemblies where LS-series compatibility is required. Industrial automation controllers and embedded educational platforms also use it to interface microcontroller I/O ports with shared TTL buses.

Frequently Asked Questions
How are the enable pins on the SN74LS367ADG4 organized across its 6 buffer channels?
The 6 channels are divided into two groups: one enable controls 4 channels and a second enable controls the remaining 2 channels. Each enable is active-low, placing the associated outputs in the high-impedance 3-state when deasserted. This two-group architecture supports flexible bus partitioning in TTL systems operating from 4.75 V to 5.25 V.
What is the output drive current of each channel and what load capacitance is it rated for?
Each buffer output can sink up to 24 mA and source current consistent with LS-TTL logic, rated for a load capacitance of 45 pF. These parameters are sufficient to drive standard TTL bus lines with typical fanout requirements, maintaining valid logic levels across the 4.75 V to 5.25 V supply range.
When would a designer choose the SN74LS367ADG4 over the SN74LS244 octal buffer?
A designer would choose the SN74LS367ADG4 when exactly 6 buffered lines with two independent enable groups are needed in a 16-pin SOIC package, rather than 8 lines in the 20-pin SN74LS244. The hex arrangement is common in 6-bit address sub-bus designs and reduces pin count when all 8 channels of a larger octal device are not required.
Is the SN74LS367ADG4 suitable for replacement in boards that used the older 74LS367 DIP part?
Yes, the SN74LS367ADG4 is the surface-mount SOIC equivalent of the through-hole 74LS367 DIP. Both operate from 4.75 V to 5.25 V with identical logic function, 24 mA sink current, and 45 pF load capacitance ratings. An adapter or footprint redesign is required to move from the original 16-pin DIP to the 16-pin SOIC package during board respins.
