Applications
The SNJ54ALS258AJ is used in military and aerospace digital systems for 4-bit data multiplexing, bus switching, and signal selection where inverted output data and 3-state bus capability are required. Its 3-state outputs allow multiple devices to share a common output bus, making it suitable for backplane data routing, address multiplexing, and bidirectional bus arbitration in ruggedized computing and avionics equipment.

Frequently Asked Questions
What is the SNJ54ALS258AJ and what are its key functional differences from SNJ54ALS157AJ?
The SNJ54ALS258AJ is a quadruple 2-to-1 inverting multiplexer with 3-state outputs, while the SNJ54ALS157AJ is a non-inverting multiplexer without 3-state capability. The ALS258 adds both output inversion and 3-state (high-impedance) output control via an active-low enable input, allowing multiple ALS258 devices to share a common output data bus without contention.
How does the 3-state output work on the SNJ54ALS258AJ?
The SNJ54ALS258AJ has an active-low ENABLE input that controls all four output channels simultaneously. When ENABLE is asserted (low), the selected multiplexer data (inverted) appears on the outputs. When ENABLE is deasserted (high), all four outputs enter a high-impedance state, effectively disconnecting the device from the output bus and allowing other bus drivers to take control.
What is the output sink current of the SNJ54ALS258AJ?
The SNJ54ALS258AJ provides a maximum output sink current (I(ol)) of 12mA, which is sufficient to drive standard TTL loads and moderate bus capacitances at ALS family switching speeds. This drive level is appropriate for on-board data routing applications where the SNJ54ALS258AJ is one of several devices sharing a common 5V logic bus.
What temperature range and package does the SNJ54ALS258AJ support?
The SNJ54ALS258AJ is housed in a 16-pin ceramic dual in-line package (CDIP) with JESD-30 code R-GDIP-T16, rated for military temperature range from -55°C to +125°C. The ceramic enclosure provides hermetic protection against moisture ingress and chemical contamination in harsh military and aerospace operating environments requiring long service life.
