Logic Flip Flops are an important component of digital-circuits, providing their basic functions like memory, decision making and data transfer. The 74HCT377N,652 is one such type, a high–speed and low-power logic flip flop.

From a architectural point of view, the 74HCT377N,652 is a master-slave D flip-flop. It consists of a two stage D-Type Flip-Flop with two clock pulse inputs, Clock (CP) for the master and Clock-inhibit ( CK-INH) for the slave and a data input (Data In). When the slave clock input CK-INH is low, then the CLK input will be enabled and data on the data-input pin is shifted to the output after falling edge of the CLK signal. When the CK-INH is high, the CLK signal is ignored and any data present on the data input pin is shifted to the output after the rising edge of the CLK signal.

The 74HCT377N,652 also provides the additional set and reset functions, through the active-low Set (S) and active-low Reset (R) inputs. It is worth noting that the Set (S) and Reset (R) pins can be disabled when left open or taken to a logic high level. This property is useful for combining two flip-flops for making a larger memory or as a data isolator as used when handling multiplexer data.

The set and reset functions of the 74HCT377N,652 can be used to generate a type called “residue” mode operation, which enables the user to extend the number of states that can be achieved in a finite number of clock cycles. In short, these functions can be used to simplify the design and at the same time, make the system faster.

An important feature of the 74HCT377N,652 is its ability to be operated at 5-volt level while keeping the output low power and noise immune. This makes the device suitable for modem Logic and Bus applications, as well as embedded systems.

The 74HCT377N,652 can easily be interfaced with either TTL or CMOS logic circuits. It is an ideal solution for those applications that require a low-power and high-speed logic flip-flop.

In summary, the 74HCT377N,652 is a powerful, low-power and high-speed logic flip-flop used for data memory and transfer in digital systems. It is also used for implementing residue mode operation as well as for interfacing with TTL/CMOS logic circuits.
