SN54HC373VTDG1 Datasheet/PDFLogic - Latches
The SN54HC373VTDG1 is part of the Logic - Latches category, which boasts wide applicability and is used for various applications. Logic - Latches basically utilizes the memory which is composed of two states - 0 (reset) and 1 (set) - to ‘latch’ an output signal. It is used in a variety of applications that require a signal to be held in whatever state it is in until the condition changes.
Application Fields
The SN54HC373VTDG1 is a common type of Logic - Latches used in a variety of application fields. Examples of application fields where SN54HC373VTDG1 is used include data acquisition, signal buffering, signal routing, interception, and transmission. It is also commonly used in operation systems, such as microcontrollers, embedded systems, and programmable logic controllers (PLCs), as well as other applications.
Working Principle
The operation of Logic - Latches is based on the concept of memory. Latches are essentially memory devices that remember stored states. When a signal is applied to the first input, the signal’s state is stored in memory. When the same signal is applied to a second input, the memory contents are reversed. In short, a latch is a digital circuit that maintains a binary state.
The SN54HC373VTDG1 operates on a similar principle, where it stores and reverses the state of a signal from one input to another. It is typically used to interface two different logic systems, where one logic system is used to store and retrieve information from another. It is composed of two NAND gates connected in series, with two additional NAND gates forming an inverter. The output of the first NAND gate is connected to the Latch Enable (LE) input, which allows for two separate control inputs to the same circuit.
In operation, the LE input is most commonly used to ‘set’ or ‘reset’ the latch. When the LE input is set to ‘LOW’ a ‘reset’ condition is established, which sets the output to ‘OFF’. When the LE input is set to ‘HIGH’, a ‘set’ condition is established, which sets the output to ‘ON’. Once the output is in the desired state, it will remain there until the LE input is set to the opposite state.
The SN54HC373VTDG1 is a popular and widely used type of latch. Its flexibility and ease of use make it a popular choice for many different types of applications, from data acquisition to signal routing, interception, and transmission. The SN54HC373VTDG1 operates on a simple principle, allowing for two separate control inputs to achieve the desired logic state.
