What are the key features of SNJ54LS367AJ?
- Hex 3-state non-inverting bus driver with two independent active-low enable groups supports flexible bus sharing on 5 V backplane designs
- Military-grade ceramic 16-pin DIP (CDIP) package meets MIL-STD-883 and is qualified for -55°C to 125°C operation in harsh aerospace environments
- LS-family TTL compatibility allows direct interfacing to legacy 5 V microprocessors and bus controllers without additional level shifting
What is SNJ54LS367AJ used for?
SNJ54LS367AJ is used in military avionics, space subsystems, and ruggedized industrial controllers where ceramic-packaged logic ICs must operate reliably across -55°C to 125°C temperature extremes. Its tri-state outputs allow multiple bus drivers to share a common address or data bus without contention, making it useful in 8-bit backplane systems and legacy 5 V microprocessor boards. The part is also a drop-in replacement for 54LS367 devices in existing defense hardware undergoing lifecycle extension.

Frequently Asked Questions
What temperature range does SNJ54LS367AJ support, and why is the ceramic package important for military use?
SNJ54LS367AJ is rated for -55°C to 125°C full military temperature range. The ceramic DIP (CDIP) package provides hermetic sealing that prevents moisture ingress, which is critical for long-term reliability in aerospace, military avionics, and satellite subsystems where plastic packages would fail due to humidity, vibration, or thermal cycling over multi-decade operational lifetimes. Most commercial 74LS367 equivalents are only rated 0°C to 70°C commercial range.
How do the two enable inputs of SNJ54LS367AJ allow partitioned bus driving across 6 channels?
SNJ54LS367AJ has two active-low enable pins: one controls channels 1 through 4 and the other controls channels 5 and 6, allowing the 6 outputs to be split into a 4-bit group and a 2-bit group. When an enable pin is high, its associated outputs go to high impedance (3-state), disconnecting those drivers from the bus. This grouping is useful in 8-bit bus architectures where separate nibble or byte-lane enables are needed, such as address and data bus multiplexing in legacy 5 V microprocessor systems.
Is SNJ54LS367AJ a direct replacement for the commercial SN74LS367A in a 5 V TTL system?
Yes, SNJ54LS367AJ is functionally identical to SN74LS367A and uses the same 5 V supply, TTL-compatible input thresholds, and 3-state non-inverting output configuration. The primary difference is the SNJ54 prefix indicating military screening (extended -55°C to 125°C range, ceramic package) versus the SN74 commercial grade. Pin-for-pin compatibility means the ceramic-packaged military part can replace the plastic commercial version in a 16-pin DIP socket without any schematic or layout changes, which is valuable during hardware re-qualification programs.
