Logic - Latches is a type of digital circuit that has two stable states and is used to store state information. The MM74HC573N is an 8-bit static latch which agrees with the high-speed CMOS that is produced using silicon gate C2MOS technology. This 8-bit static latch provides a storage of logic states, the MM74HC573N can store eight separate data bits and provide the output in synchronization with clock input. This 8-bit static latch is equivalent to two 4- bit latches and two separate clock inputs are used for independent operation of each 4-bit latch.Here are some applications and working principles of MM74HC573N.

Applications of MM74HC573N

The MM74HC573N can be used as digital segment drivers, such as LED display drivers. This 8-bit static latch can also be used as a multiplexer, digital logic functions, handshaking and also as a shift register. Briefly, the application field of MM74HC573N include but not limited to the following:

• Driving LED displays
• Multiplexers
• Digital logic functions
• Handshaking
• Shift register

Working Principles of MM74HC573N

The MM74HC573N consists of two 4-bit storage registers and two different sets of five-stage data latches. This 8-bit static latch is designed for use in digital systems to respond to control signals and establish a given status determined by the control signals and latched data. The synchronized pins (CP1 and CP2) are the clock inputs of each 4-bit static latch. The master reset pin (MR) acts as a reset when a voltage level is applied to this pin.

The 8-bit static latch consists of two 4-bit static latches (A and B) and they have one data input (DA1, DB1) and four outputs (QA1~QA4, QB1~QB4). If the CP pins are set to high, the latched state of the data input will be stored, and the inverted output will be updated. The data is latched one by one, and each 4-bit static latch will be updated to the same state.

The MM74HC573N uses asynchronous master reset, this reset is active low and is asynchronous to the clock and data. When MR is active, the data outputs are forced to ‘0’, independent of the inputs and clock. If a low-level signal is applied to MR pins, both 4-bit static latches will be reset to the initial state.

The MM74HC573N chip is more suitable for digital systems because of their low power dissipation, large fan-out and high noise immunity, among other features. This 8-bit static latch is suitable for high-speed memory applications because the raise and fall times can reach a minimum of 10ns, with a maximum of 30 ns.

As mentioned above, The MM74HC573N is an 8-bit static latch which is designed with two 4-bit static latch and two clock inputs. The MM74HC573N has various applications such as LED display drivers, Multiplexers, Digital logic functions and even shift register. It has an asynchronous master reset pin which is able to reset the data outputs when a low-level signal is applied to it. The MM74HC573N shows good performance because of its low power dissipation and high noise immunity.
