Logic-latches have been around since the dawn of computing. They provide a strong, reliable and convenient way to store data. One type of logic-latch, the SN74LVC16373ADLR, is a particularly integral component of modern circuits. Here, we’ll explore the application field and the working principle of the SN74LVC16373ADLR.

The SN74LVC16373ADLR is an octal (8-pin) bidirectional transceiver latch. It works with both 3.3V and 5V power supplies, making it a great choice for multi-voltage systems. It features integrated bus-hold which locks in the data once read, as well as live insertion/removal support. The active-low output-enable pin controls the direction of data flow between the inputs and the outputs. With low power consumption, the latch is well suited for use in the most power-sensitive applications such as automotive or battery-powered equipment.

The SN74LVC16373ADLR is ideal for a wide range of applications. Its low power consumption and high speed make it well suited for FPGA/ASIC designs and various embedded systems. Its integrated bus-hold makes it ideal for LCD controllers, as well as memory control logic in systems. Its live insertion/removal feature makes it suitable for interface logic in systems in which removable modules need to be supported, such as CAN networks. Moreover, its high noise immunity makes it suitable for signal conditioning in industrial equipment.

The SN74LVC16373ADLR is a popular choice for many applications, thanks to its functional features as described above. But what is the working principle of the latch? As with any logic-latch, the SN74LVC16373ADLR is a bi-directional transceiver that holds the data in the output register until instructed to load in new data. The latch is controlled by an active low output enable (OE) signal, which allows the flow of data either from input to output (1-0) or from output to input (0-1). When the OE input is high, the outputs are in a high-impedance state, thus disabling any data transfer.

On the SN74LVC16373ADLR, the assertion of the OE signal starts a data-loading process. If data is transferred from the input side to the output side, the input data is clocked into the input register, where it is held until the OE signal is de-asserted. At the same time, the data is transferred to the output register and applied to the output pins. Once the OE is de-asserted, the data in the input register is latched into the output register, where it is held and output until the next OE assertion. If the latch is transferring data from the output side to the input side, the process is similar, with the output data being clocked into the output register first and then transferred to the input register where it is held until the OE signal is de-asserted. Then, the data is latched into the input register and output until the next OE assertion.

These are the workings of the SN74LVC16373ADLR, a popular latch for multi-voltage systems. With low power consumption, integrated bus-hold, live insertion and removal, and high noise immunity, it’s an ideal choice for many applications including FPGA designs, LCD controllers, industrial equipment, and CAN networks. The latch is a powerful asset to the modern circuit, and its working principle is one worth knowing.
