Applications
The SN54LS367AJ is used in military and high-reliability embedded systems where 3-state bus buffers must isolate data lines between CPU, memory, and I/O subsystems operating at 5 V TTL levels. Its ceramic DIP package and military-grade temperature rating make it a preferred choice for avionics, defense electronics, and ruggedized industrial controllers. The device also serves in legacy bus interface designs where direct replacement of older 74LS367 logic is required.

Frequently Asked Questions
How many independent output channels does the SN54LS367AJ provide, and how are they enabled?
The SN54LS367AJ provides 6 non-inverting 3-state output channels organized into two groups of 2 bits each, with separate active-low enable inputs controlling each group. When an enable input is deasserted high, the associated outputs enter a high-impedance state, releasing those lines from the bus at standard 5 V TTL logic levels.
What temperature range does SN54LS367AJ cover, and why is its package significant for harsh environments?
The SN54LS367AJ covers a full military temperature range of -55 °C to +125 °C in a ceramic 16-pin DIP package. The ceramic hermetic package resists moisture ingress and thermal shock better than plastic equivalents, making it appropriate for avionics, satellite ground systems, and defense electronics that must survive harsh operating environments over decades.
What is the propagation delay of SN54LS367AJ and how does it compare within the LS logic family?
Typical propagation delay for the SN54LS367AJ is approximately 10 ns from input to output at 5 V supply and 25 °C, consistent with the LS-TTL family specification. This speed supports bus arbitration and data multiplexing at clock rates up to tens of megahertz in 8-bit and 16-bit TTL bus architectures, where buffer latency must be budgeted within system timing margins.
When is SN54LS367AJ preferred over the commercial SN74LS367A in a board design?
SN54LS367AJ is chosen over SN74LS367A when a design must qualify for military or high-reliability screening, requiring operation from -55 °C to +125 °C rather than the 0 °C to +70 °C commercial range. Military programs often mandate the 54-series ceramic package to meet MIL-STD or NASA part qualification requirements, even though both devices share identical 5 V electrical characteristics and 16-pin pinouts.
