Frequently Asked Questions
What is the maximum clock frequency of the SN74ALS174N?
The SN74ALS174N supports a maximum clock frequency of 50 MHz at nominal supply voltage. This high-speed performance is characteristic of the ALS (Advanced Low-Power Schottky) logic family, making it suitable for fast digital designs in computing, communications, and industrial control applications.
How does the clear function work on the SN74ALS174N?
The SN74ALS174N features an active-low asynchronous clear input (CLR) that resets all 6 flip-flop outputs to logic LOW simultaneously, regardless of the clock state. This is useful for system initialization or error recovery. The clear operates independently of the clock, allowing instantaneous reset of all stored data.
What package and pin count does the SN74ALS174N use?
The SN74ALS174N is housed in a 16-pin Dual-In-Line Package (DIP), also known as PDIP-16. This through-hole package is well-suited for prototyping, breadboarding, and legacy PCB designs. The 0.1-inch pin pitch makes it compatible with standard IC sockets and easy to handle manually.
What are typical applications for the SN74ALS174N?
The SN74ALS174N is commonly used as a data latch or pipeline register in microprocessor systems, FPGA interface circuits, address bus buffers, and state-machine designs. Its 6-bit width and fast ALS switching make it ideal for parallel data capture in industrial control, test equipment, and embedded computing.
Is the SN74ALS174N RoHS compliant and still available to purchase?
Yes, the SN74ALS174N carries a Pb-free (RoHS compliant) designation with JESD-609 code e4, confirming it meets modern environmental standards. It is available for purchase from major distributors starting from approximately $0.40 per unit, with worldwide shipping options for both small and volume orders.
