The 74LVQ273SC is a 3-state noninverting bus register ideal for input/output port configuration. It has an output enable (OE) feature that enables the outputs to either be classified as either HIGH-Z, logic 1, or logic 0, complimentary to the outputs. This device has eight outputs and an enable input pin that control the output enable of all of the outputs. This IC belongs to the category of logic devices called flip-flops, and its characteristics is focused on its ability to register and store one bit of data. In order to discuss its application field and working principle, we have to differentiate between two major types of flip-flops, SET and RESET.
The SET flip-flop is composed of two logic elements and two inputs. Its working principle is to set the output to logic 1 when the two inputs, S and R, are both HIGH. In reset mode, the output will be set to logic 0 when R is HIGH and S is LOW. This flip-flop type is mainly used in holding registers, where the output must remain at logic 1 even if S is low. As a result, this type of flip-flop is quite reliable and stable.
The RESET flip-flop is based on an ex-or gate and an inverter. Its working principle is to reset the output to logic 0 when one of the two inputs, S and R, is HIGH and it sets the output to logic 1 when both S and R are LOW. The main application of this type of flip-flop is in generating clock signals for digital systems. The RESET flip-flop is also utilized for generating start/stop signals for various other applications.
The 74LVCQO73SC is a SET based flip-flop type, meaning its logic elements are set up in a way that the output is set to logic 1 when both the set and reset inputs are HIGH. This flip-flop offers inputs and outputs that can be set to either logic 1, logic 0, or a HIGH-Z state. It also offers an enable/disable feature that allows the user to control the output enable of all the outputs. This feature is also known as a buffer enabling a single unity to activate logic level signals on multiple levels.
The 74LVQ273SC has the ability to store data, making it easy to use in various applications. Its primary application field is memory systems, where it can be used to store and output data. Its enable/disable feature also adds flexibility to the device making it very useful in various applications. It can also be used as part of an interface, providing direct connection between data and input/output ports, as well as being able to control when data is to be transferred. The 74LVQ273SC is an ideal choice for both input/output port configurations and data storage applications.
The working principle of the 74LVQ273SC is quite simple. It is equipped with two inputs, SET and RESET, which are both connected to logic 1 in order to set the output to logic 1. When the SET input is taken to a logic 0 and the RESET input is kept at 1, the output is set to logic 0 and the Flip-Flop is in the reset mode. In order to reset the flip-flop and set the output back to logic 1, the inputs will need to be flipped, that is, SET to logic 1 and RESET to logic 0.
The 74LVQ273SC is an ideal choice for applications that require data storage, or for interface purposes at the input/output port configuration level. The device can be used in various applications such as memory systems, data transfer controllers, state machines, counter circuitry, and input hold registers. With its ability to combine both the SET and RESET type flip-flops, the device is immensely versatile and reliable, making it one of the most popular digital devices in use today.
