Frequently Asked Questions

What type of counter is the SNJ54ALS163BJ?

The SNJ54ALS163BJ is a synchronous presettable 4-bit binary counter that counts upward and features synchronous parallel load, synchronous clear, and a terminal count output for easy cascading.

What does the TCO output do on the SNJ54ALS163BJ?

The terminal count output (TCO) goes high when the counter reaches its maximum count of 15, providing a carry signal that can directly clock or enable adjacent counter stages for cascaded multi-bit counting without glitches.

What is the temperature range for the SNJ54ALS163BJ?

The SNJ54ALS163BJ is a military-grade device rated for operation from -55°C to 125°C, making it suitable for aerospace, defense, and other high-reliability industrial applications.

What package does the SNJ54ALS163BJ come in?

The device is housed in a 16-pin ceramic dual-in-line package (CDIP), which provides superior hermeticity and mechanical durability compared to plastic packages, critical for military qualification.
