Logic - Latches
The SN74LV573ATDW is a 8-bit latch, available in smaller packages and with lower power dissipation than conventional 10-bit latches. It is a highly versatile shifter/latch, designed to enable 64-bit data transfer and multiplexing applications in various data communication systems. It has eight data inputs (D0-D7) and eight data outputs (Q0-Q7). The data can be shifted in or out one bit at a time on each successive pulse of the Clock (CLK) input, which is an active high signal. The data can also be latched at the outputs using the Latch Enable (LE) signal, which is an active high signal that can be pulsed.
The SN74LV573ATDW is used for applications such as multiplexing, data transfer, data routing, data acquisition, buffering, memory and register support, bus emulation, and parity checking. It is also useful in selecting among a group of signals, high speed scanners, and equipment status indicators. In addition, the latch can be used for data bus summing, high-speed video signal multiplexing, video RAMS, and as a direct addressable latch for bigger ROMS.
SN74LV573ATDW Working Principle
The SN74LV573ATDW works using a pulsed clock input, which means that the clock signal must be off and then clocked on and off again when data is to be shifted. The Clock signal is used to latch the data into the output shift register. The Latch Enable (LE) signal is used to latch the data into the output shift registers. The data is unloaded on every cycle of the clock, and the data can be shifted out of the output one bit at a time.
The time delay between the clock pulse and the pulse of Latch Enable is referred to as the Latch Delay. This delay ensures that there is sufficient time for the data to be sampled and loaded into the output shift registers before the clock pulse drives the data out. The data is clocked into the output shift register from the 8-bit D input during each clock pulse. The data is then held in the output shift register until the LE signal is pulsed. When the LE signal is pulsed, the data can be latched into the output shift registers.
The shift register in the SN74LV573ATDW is designed to work with the 3-State Inhibit (INH) signal. The INH signal allows the output shift registers to be controlled and data path to be switched off. When the INH is active (high), the outputs of the latch will be High-Impedance, making them incapable of loading data. This can be used to prevent data transferring to devices with low voltage levels.
Applications of SN74LV573ATDW
The SN74LV573ATDW has a variety of applications including data transfer, data routing, data acquisition, buffering, memory and register support, bus emulation, and parity checking. It is very useful for multiplexing, selecting among a group of signals, and video signal multiplexing. It is also used for high speed scanners, equipment status indicators and for video RAMS.
The SN74LV573ATDW can be used in applications such as high speed communication systems where data needs to be transferred quickly and accurately. It can also be used in automobile, medical and industrial systems where data needs to be shifted and multiplexed. The latch can be used in various types of data buses, including 8-bit, 16-bit, 32-bit and 64-bit data buses. The SN74LV573ATDW can also be used as a register in digital and microcontroller based systems, for storing and transferring data. In addition, the latch can be used for clock synchronization or for memory devices such as DRAM and SRAM.
In summary, the SN74LV573ATDW is a versatile 8-bit latch which can be used for data transfer, multiplexing and data routing applications in various data communication systems. It can also be used for video, automotive, medical and industrial applications, and is capable of working with various types of data buses. It is available in smaller packages and with lower power dissipation than conventional 10-bit latches, making it a great choice for applications where size and power consumption are important.
