74AC74SCX - Brand New Fairchild Semiconductor Flip Flops
-
Description
The 74AC74SCX is a dual D-type flip-flop with asynchronous clear and set inputs and complementary (Q, Q) outputs. It transfers information from the input to the outputs on the positive edge of the clock pulse. The clock triggering occurs at a voltage level of the clock pulse and is not directly related to the transition time of the positive going pulse. The data input is locked out after the clock pulse input threshold voltage has been passed, and the information present will not be transferred to the outputs until the next rising edge of the clock pulse input.
Specifications and features
The 74AC74SCX features asynchronous inputs that allow for independent clearing and setting of the flip-flop. A low input to the set input (SD) sets the Q output to a high level, while a low input to the clear input (CD) sets the Q output to a low level. Clear and set are independent of the clock, and a simultaneous low on CD and SD will make both Q and Q outputs high. In addition, the 74AC74SCX offers the following features:
- ICC reduced by 50%
- Output source/sink 24mA
- ACT74 has TTL-compatible inputsApplication Scenarios
The 74AC74SCX can be used in various applications that require flip-flop functionality. It is commonly used in digital circuits to store and transfer data, such as in counters, registers, and sequencers. The asynchronous clear and set inputs make it suitable for applications where precise timing is not critical, or when the clearing and setting of the flip-flop need to be controlled independently of the clock signal.
Comparison
Advantages- ICC reduced by 50% compared to previous models, resulting in lower power consumption.
- Output source/sink 24mA, allowing for strong signal driving capability.
- ACT74 has TTL-compatible inputs, making it compatible with a wide range of digital systems.Disadvantages- The asynchronous clear and set inputs may introduce potential timing issues in applications where precise timing is critical.
- The D-type flip-flop functionality may not be suitable for all types of digital circuits or applications. -
