As a member of the Texas Instruments (TI) SN74AHC logic family series, SN74AHC16374DGGR is a dual positive-edge-triggered D-type flip-flop with separate clocks. The device has two independent edge-triggered D-type flip-flops with independent J and K inputs, clock, and asynchronous preset (Pr) and clear (Clr) inputs. The flip-flop\'s operation is dependent upon both the level and the edge (positive or negative transition) of the clock. The device can be used for counting, frequency division, making a frequency selector, or gating operations.

SN74AHC16374DGGR consists of two flip-flops. It contains two independent D-types where each one is triggered on positive transitions of its corresponding CK clock input. There are two data inputs, named D and nD, and each one is associated with its own clock. The device also has a “J” and “K” input for each slave D-type flip-flop.

The device has two separate asynchronous inputs for resetting and clearing its output values. These two inputs have the opposite logic. It means that when one of them is set its output will be zero and when the other one is set its output will be one.

When the clock is at the low level, the contents of the master flip-flop will be transferred to the slave flip-flop. The inputs of this device are intolerant of floating electrodes: that is, in the state with no input signal applied, no output should be produced. Depending on the input logic levels, the operation of this device, as a two inputs multiplexer, features a ‘low-impedance’ transmission, with a wide digital-level input-voltage range, of: 0.3 to > VCC.

The working principle of a SN74AHC16374DGGR can be summarized as follows: the flip-flop receives two D inputs, a JK input and a CK clock, and then outputs two Q and nQ outputs. Depending on the logic levels of the inputs, the flip-flop can be in a clocked, reset, or preset state. When in a clocked state, signals are latched into the flip-flop, when in a reset state, the output is reset to zero, and when a preset state , the output is set to one. The level of the CK clock will determine whether the flip-flop is clocked, reset, or preset. Depending on the states of the JK inputs and the CK clock, the logic levels at the output will be determined.

Due to its modularity, the SN74AHC16374DGGR is used in a wide range of applications such as controlling digital logic (high-speed or parallel digital circuits, digital filters, and memory elements). Also, it is used in filtering, audio/video switching, calculations, bus arbitrations, laboratory digital systems, etc. These devices are also designed to be used in portable electronic systems for automobile and consumer applications, where the device’s low power consumption is an important benefit.

In short, the SN74AHC16374DGGR is a versatile logic device and has a wide range of uses in a variety of applications, from audio and video switching and filtering, to precision calculations and memory elements. Its low power consumption makes it suitable for portable consumer applications, and its edge-triggered clocking enables precise and reliable control of digital logic.
