Frequently Asked Questions
What is the supply voltage range of the SNJ54AHCT32J?
The SNJ54AHCT32J operates from a supply voltage of 4.5 V to 5.5 V, making it compatible with standard 5 V logic systems. Its AHCT logic family ensures TTL-compatible input thresholds, allowing direct interfacing with both TTL and CMOS devices without level-shifting circuits.
What package does the SNJ54AHCT32J use and why is it significant?
The SNJ54AHCT32J comes in a 14-pin ceramic dual-in-line package (CERDIP), designated as R-GDIP-T14 per JESD-30. The ceramic package provides superior hermeticity and thermal stability compared to plastic packages, making it essential for military and aerospace applications that must withstand harsh environmental conditions including extreme temperatures and humidity.
How many logic functions does the SNJ54AHCT32J provide?
The SNJ54AHCT32J contains four independent 2-input OR gates in a single 14-pin package. Each gate can handle two binary inputs and produces a high output when either or both inputs are high, supporting up to four separate logic operations simultaneously with an output sink current of 8 mA per channel.
What are the typical applications for the SNJ54AHCT32J?
This device is designed primarily for military, aerospace, and high-reliability industrial applications. It is commonly used in bus arbitration logic, interrupt enable circuits, signal multiplexing, and any application requiring robust OR logic operation with TTL-compatible inputs in environments subject to temperature extremes, vibration, or other harsh conditions.
Is the SNJ54AHCT32J RoHS compliant?
Yes, the SNJ54AHCT32J carries a Pb-free code of 'Yes' and a JESD-609 code of e0, indicating it meets RoHS requirements and is manufactured without lead.
