Frequently Asked Questions
What is the maximum operating frequency of the SN74ALS74AN?
The SN74ALS74AN supports a maximum clock frequency of 34 MHz at nominal supply voltage. This makes it suitable for medium-speed digital logic applications in the ALS family, offering a good balance of speed and low power consumption.
What package does the SN74ALS74AN come in, and what are its pin dimensions?
The SN74ALS74AN is available in a 14-pin Dual-In-Line Package (DIP). The JESD-30 code is R-PDIP-T14, making it compatible with standard 0.1-inch pitch breadboards and through-hole PCB designs, ideal for prototyping and low-volume production.
Can the SN74ALS74AN be used as a frequency divider?
Yes. By connecting the Q-bar output back to the D input, each flip-flop in the SN74ALS74AN divides the input clock frequency by 2. With two independent flip-flops, cascading them achieves divide-by-4 operation, useful in timing and clock generation circuits.
What are common alternatives or substitutes for the SN74ALS74AN?
Compatible alternatives include the SN74LS74A (LS logic family, lower speed), SN74HC74 (CMOS, wider supply range), and SN74ACT74 (ACT logic, 5V tolerant with CMOS speeds). Always verify voltage, timing, and drive specifications before substituting in your design.
