What are the key features of SNJ54ALS873BJT?
- 8-channel transparent D-type latch with 3-state outputs for high-density bus interface designs in military-grade systems
- Active-low enable input and separate asynchronous clear function for flexible bus control and initialization without power cycling
- ALS (Advanced Low-power Schottky) logic family delivering 50 pF load capacitance drive and fast propagation times at reduced power versus standard LS
- Military-grade SNJ54 temperature qualification for reliable operation across extended environments in defense and aerospace applications
What is SNJ54ALS873BJT used for?
The SNJ54ALS873BJT is used in military avionics, defense electronics, and aerospace systems requiring 8-bit data bus latching with 3-state isolation and an asynchronous clear function. Its ALS technology provides a balanced combination of speed and low power dissipation at 50 pF load capacitance, making it suitable for CPU data bus buffering and address latching in rugged embedded systems. The 24-pin CDIP package supports through-hole assembly in high-reliability boards designed to meet military environmental specifications.

Frequently Asked Questions
How many data channels does the SNJ54ALS873BJT support and what logic family does it belong to?
The SNJ54ALS873BJT is an 8-channel device in the ALS (Advanced Low-power Schottky) family. It supports unidirectional latching on 8 data lines simultaneously, with a rated load capacitance of 50 pF per output, enabling reliable bus driving in dense digital systems.
What operating temperature range does the SNJ54ALS873BJT cover?
As a military-grade SNJ54 series part, the SNJ54ALS873BJT is qualified for the full military temperature range of -55°C to +125°C, making it suitable for airborne, shipboard, and ground military electronics where commercial-grade parts would fail.
How does the 3-state output feature on SNJ54ALS873BJT help in bus-sharing designs?
The 3-state outputs allow the SNJ54ALS873BJT to disconnect all 8 channels from the data bus simultaneously when the enable input goes high, presenting high impedance. This is essential in multi-master bus architectures where multiple 8-bit devices share a single 50 pF or higher capacitance bus without signal contention.
When is SNJ54ALS873BJT a better choice than a commercial-grade 74ALS873 in a new design?
Choose the SNJ54ALS873BJT over commercial 74ALS873 variants when the application demands operation from -55°C to +125°C, full military JEDEC screening (JESD-30 code R-GDIP-T24), and higher reliability for defense or space-adjacent designs where field-failure consequences are severe and part qualification must meet military standards.
