SN74HCT377NG4

The SN74HCT377NG4 is a dual D-type flip-flop with clock and reset inputs. It is primarily used for general purpose digital logic applications and provides a logical level shift from low voltage to high voltage digital logic levels. The SN74HCT377NG4 is part of the 74HCT family of logic devices, which are TTL compatibly with logic level thresholds that can accept inputs from CMOS logic levels.

This device basically consists of two separate D-type flip-flop with set-reset inputs and clock input. The flip-flop itself is configured with a positive-edge triggered clock. This means that the data value specified at the ‘D’ input of each flip-flop is stored in the respective ‘Q’ output when an active-high clock signal transitions from low to high. This feature is useful in applications that require synchronization of multiple digital signals.

The SN74HCT377NG4 features active-low set and reset inputs which, when asserted, will force their associated ‘Q’ output to a logic low regardless of the data input (‘D’) or the clock signal. These inputs, designated as ‘SR’, should be asserted only for a brief period during which time the device should be held in reset and the corresponding output disabled.

The SN74HCT377NG4 also has a preset and clear inputs, with each flip-flop having one such input. The preset and clear inputs are active-low and are higher-up in the logic hierarchy than the clock and input signals. Whenever a logic low is applied to any of these inputs, the information stored in the associated flip-flop is immediately cleared out to a logic low and becomes latched in that state. Hence, if the clear input of both flip-flops is held low, no changes on any of the other inputs will be recognized in the associated output at all.

Applications of SN74HCT377NG4 include but are not limited to, standard digital logic operations such as data buffering, timing adjustment and logic gating. Furthermore, it can be used in logic systems to enable data to be stream synchronized, so that a continuous stream of data is synchronized with the rising edge of the clock signal of the device. In addition, these flip-flops are often used in memory design where data is written to memory during a given period and then read at a later time.

In general, the SN74HCT377NG4 is a versatile and reliable logic device that provides a total of four independent D-type flip-flops configured as a dual latch. It is a great choice for digital logic applications where synchronization of digital signals is needed. The device meets all industry standards and is available in a range of power-saving packages. This makes it suitable for use in battery powered applications.
