SN74ALS573CNSRE4

The SN74ALS573CNSRE4 are advanced low-power Schottky devices that belong to the TTL family of integrated circuits. These circuits have a high degree of compatibility with the TTL technology, making them popular in many applications and design implementations. Specifically, in many cases, the SN74ALS573CNSRE4 devices are classified as belonging to the group of logic – latches.

A latch, or commonly known as a flip-flop is a storing device that is based on two logic levels, which can be either High or Low. The latch’s input is determined by the logic level at its two inputs. If both inputs are at the same logic level, either both HIGH or both LOW, the latch remains in its original stable state. This is known as the Data input/Set input. On the other hand, if the logical level at the second input, the Clock input, is changed, then the output of the latch is changed accordingly. It is this type of circuit that is exploited when we use our SN74ALS573CNSRE4 devices.

The SN74ALS573CNSRE4 is a 8-bit dynamic latch array which performs the same as a J-K flip-flop. It has a D-type latch for each bit which is driven by the data and the clock input of its latch. This device has a 36-pin DIP package with the individual pins providing easy access for both the clock input and the data inputs for each of the 8-bits. In addition to that, the SN74ALS573CNSRE4 also has a chip select (CS) pin which is active-low and additionally, each of the latches have separate /CS pins.

This device is mainly used in applications that require data storage in the form of signals, either digital or analog. Its applications vary from simple one-shot pulse producing applications to microcomputer data acquisition and control applications. Since the SN74ALS573CNSRE4 device is a simple latch array, not only can it be used in data acquisition and control but also in interfacing different integrated circuits. This device can also be used in more complex applications, like those of a sequencer, shift register, counter and more.

In conclusion, the SN74ALS573CNSRE4 device is a highly versatile device which can be used in many applications, like those irrespective of its original purpose as a logic - latch. These devices have a low power requirement, making them Energy Star compliant, which makes them a great option for applications that are battery or energy conscious.
