SN74LV573ATRGYRG4

Logic - Latches is a comprehensive term for several types of digital circuits. One kind of Logic - Latches is the SN74LV573ATRGYRG4 which is a dual-channel latch with a built-in reset circuit. The SN74LV573ATRGYRG4 belongs to the low-voltage TTL family of 74xxx logic devices which consists of logic gates, flip-flops, counters, shift registers and multiplexers.

As the name implies, the SN74LV573ATRGYRG4 is designed to latch two sets of bits. Each latch has 5 separate inputs, CLK, RST, D, Q and QNA. CLK is the clock pin which is used to capture the data. RST is the reset signal which is used to reset the state of the latch to logical 0. D is the data input which is used to feed the data into the latch. Q is the output pin in which the data is captured. Finally, QNA stands for “Q Not Available” and is used as an output pin when CLK is not active.

In addition to its ability to latch two sets of 8-bit data using asynchronous reset, the low voltage SN74LV573ATRGYRG4 has several other noteworthy features. These features include hot insertion protection, high output drive capability, power consumption of less than 3 mW, wide range of operation voltage (3 - 15V) and thermal shutdown feature that eliminates latch-up associated with CMOS inputs.

The SN74LV573ATRGYRG4 is put to use in several applications, such as data transfer, communication and memory buffering, as well as clock division, signal pacing and audio and video signal switching, to list a few. The combination of its high-speed performance, low power requirements and wide range of operating voltage make it an ideal choice for design engineers.

The working principle of the SN74LV573ATRGYRG4 can be explained with the help of a clock and an asynchronous reset. When the CLK signal becomes active, the latch captures the data present on the D pin and stores it in the latch. The Q pin then displays this data as long as the CLK signal remains active. If the RST signal is activated, the entire latch is reset to logic 0. This means that the previously stored data on the Q pin is no longer available and the QNA pin displays logic 0.

In conclusion, the SN74LV573ATRGYRG4 is a dual-channel latch with a built-in reset circuit. It is designed to latch two sets of bits and is used in a wide range of applications. Its low power consumption and wide range of operating voltage make it an ideal choice for design engineers. Its working principle is based on clock and asynchronous reset and involves capturing data on the D pin and displaying it on the Q pin when the CLK signal is active.
