Frequently Asked Questions
What is the difference between SNJ54ALS157AJ and SNJ54ALS158J?
The SNJ54ALS157AJ presents true (non-inverted) data at its outputs, while the SNJ54ALS158J presents inverted data. According to Texas Instruments, the ALS158 inversion is designed to minimize propagation delay time, making it preferable in applications where the added inversion stage aligns with downstream logic requirements.
How many multiplexers are in the SNJ54ALS158J and how are they controlled?
The SNJ54ALS158J contains four independent 2-to-1 multiplexers sharing a common SELECT input that simultaneously controls all four sections. A common active-low STROBE (enable) input forces all outputs to the high logic level when deasserted, allowing bus isolation or output disable functionality.
What package does the SNJ54ALS158J use and what is its temperature range?
The SNJ54ALS158J is housed in a 16-pin ceramic dual in-line package (CDIP) with JESD-30 code R-GDIP-T16, designed for military temperature range from -55°C to +125°C. The ceramic package provides superior moisture resistance and thermal performance compared to plastic PDIP packages for harsh environment applications.
Is the SNJ54ALS158J compatible with standard TTL logic levels?
Yes, as a member of the ALS (Advanced Low-power Schottky) bipolar logic family, the SNJ54ALS158J is fully compatible with standard TTL voltage levels. It has a maximum output sink current of 4mA and operates from a 5V supply, making it directly interoperable with other TTL and ALS logic devices in mixed-logic designs.
