Introduction of 74ALVC16374DTR & Application Field

74ALVC16374DTR is an 17-bit high speed dual-register-type non-inverting buffer, consisting of 17 D-type flip-flops with transparent, positive-edge triggered, and master reset inputs. It allows data present at its D inputs to be transferred to its Q outputs simultaneously with the LOW-to-HIGH transition of its clock inputs.In the field of flip-flops and logic circuits, the 74ALVC16374DTR is one of the most widely implemented logic devices. Its main application areas are military, aerospace and space, high energy physics, ATE (automatic test equipment), medical, industrial control, and other fields which require isolation and reliability. Other applications include embedded systems, test instruments, optical processing, motor controllers, storage systems, scientific computation, and communications systems.

Functional Principle of 74ALVC16374DTR

The 74ALVC16374DTR has two synchronous data registers, A and B, each with 17 D-type flip-flops enabled by separate clocks, CKA and CKB. Each register can be loaded asynchronously by means of the common reset input, which also synchronizes the output of each register during reset.The 74ALVC16374DTR is a non-inverting device; in other words, the output state of any flip-flop is always the logical complement of the state of its associated D input. Even though the flip-flops can change state at any time and are only affected by a LOW-to-HIGH transition on the clock inputs, they do not respond to inputs other than the clock and the reset input. When the clock inputs (CKA and CKB) are LOW, the associated output drivers remain in their current conditions.

Advantages of 74ALVC16374DTR

74ALVC16374DTR offers some advantages over other logic devices, namely high speed and low power consumption with a wide common mode range. In terms of speed, the device can shift data at up to 137 MHz - equivalent to approximately 6ns of delay time. This is especially advantageous in applications where circuit speed dictates the performance of the system. The 74ALVC16374DTR also offers a very low power consumption of 25µA typical at 3.3V. This number makes the device suitable for battery operated systems needing to optimise current consumption. One of the most impressive features of the device is its wide common mode range, which typically ranges from 0.8V to 3.3V, allowing the device to be used in a variety of applications.

Conclusion

The 74ALVC16374DTR is a versatile logic device with extremely fast switching and low power consumption. It can be used in a broad range of applications and is especially suitable for military, aerospace and space, high energy physics, ATE (automatic test equipment), medical, industrial control, and other fields which require isolation and reliability. Its wide common mode range makes it ideal for applications in which circuit speed is key, and its low power consumption means that it can also be used in battery operated systems.
