Frequently Asked Questions
What is the maximum operating frequency of the SN74ALS74ANSR?
The SN74ALS74ANSR supports a maximum clock frequency of 34MHz (34,000,000 Hz) at nominal supply voltage. This makes it suitable for high-speed digital logic applications including frequency dividers, counters, and synchronous state machines operating in the tens-of-megahertz range.
What package type does the SN74ALS74ANSR use and what are its dimensions?
The SN74ALS74ANSR comes in a 14-pin Small Outline Package (SOP-14 / SOIC-14), which is a surface-mount package. The 'NSR' suffix denotes the small-outline package variant. It has a load capacitance rating of 50pF and is compatible with standard SMT assembly processes, making it ideal for compact PCB designs.
What logic family does the SN74ALS74ANSR belong to and how does it compare to other 74-series families?
The SN74ALS74ANSR belongs to the ALS (Advanced Low-power Schottky) logic family, which offers improved speed and lower power consumption compared to the original LS (Low-power Schottky) family. ALS devices typically operate at 5V VCC and provide faster switching speeds than standard TTL while maintaining TTL compatibility for interfacing with other 5V logic families.
Can the SN74ALS74ANSR be used as a replacement for SN74LS74A or SN74HC74?
The SN74ALS74ANSR is pin-compatible with SN74LS74A (LS family) and functionally equivalent, making direct substitution possible in most 5V TTL designs. However, it is not a direct replacement for SN74HC74 (CMOS), which operates over a wider voltage range (2V-6V) and has different input thresholds. Verify supply voltage and logic level compatibility before substituting in CMOS-based designs.
Where can I buy the SN74ALS74ANSR and what is the typical price?
The SN74ALS74ANSR is available from authorized Texas Instruments distributors worldwide including Digi-Key, Mouser, and Arrow Electronics. The typical unit price starts from $0.582 for standard quantities, with volume pricing available for larger orders. FindMyChip provides real-time stock comparison across multiple distributors to help you find the best price and availability.
