CD74AC112E

Logic systems and devices can be used for a variety of applications, including data processing, sensing, switching, and communication. Logic components, such as flip-flops, are vital for all these purposes as they are capable of handling logic signals, as well as storing and transmitting information. The CD74AC112E is a high-performance, bi-directional flip-flop designed to provide reliable and efficient operation in a variety of applications.

Field of Application

The CD74AC112E is designed and optimized for industrial, medical, cellular, and automotive applications in both synchronous and asynchronous systems. It is ideal for applications requiring high bandwidth, fast switching speeds, reduced noise, minimal power consumption, and high temperature operation. The device has also proven useful for board-level applications where an asynchronous optically coupled version of the flip-flop is required.

The CD74AC112E can be used for communication systems and controller designs that demand reliable data storage and transfer. The device is also capable of handling fan-out measured inputs, providing adequate power supply designs, and couple to complementing devices.

Working Principle

CD74AC112E is a dual flip-flop device comprised of two circuits that consist of two active high-impedance control inputs, two data inputs, and two outputs inverted. It is operated in a clocked state with a latch operation command (latch-enable or LE low) or by active-high SET and RESET inputs. When LE is asserted, the outputs change according to the data states at the D0 and D1 inputs on each of the flip-flops, providing that the active-low "latch enable" LE connection is left open.

At logic high, Q0 and Q1 outputs are asserted, allowing the data in D0 and D1 inputs to be transferred to their respective flip-flop outputs. At the same time, the active-low "latch enable" LE connection is left open, and the outputs of the two flip-flops remain unchanged. Similarly, when LE is deasserted, the outputs of the two flip-flops are forced to remain unchanged.

Alternatively, when LE is low, the outputs of the flip-flops change according to the data states of the corresponding data inputs. At the same time, the presence of an active-low "latch enable" LE connection confirms that the data stored in each of the cells is reliable.

Conclusion

The CD74AC112E offers efficient and reliable operation, making it the ideal choice for a wide range of logic applications. Some of its features include fast switching speeds, minimal power consumption, and high temperature operation, allowing for reliable data storage and transfer. Furthermore, the device is capable of fan-out mea sured inputs, providing adequate power supply designs, and coupling to complementing devices.
