SN74ACT573DWG4

The SN74ACT573DWG4 is an octal D-type latch from Texas Instruments that offers improved performance over the standard SN74ACT573 latch. This particular latch is best well-suited for use in bus-oriented systems, where data communications as well as peripheral devices, peripherals and other devices must be synchronized with a central source and then temporarily stored. This is due to the fact that it is a low power CMOS device and its low propagation delay, and so it is ideal for use in high switching applications, as well as bus control systems.

The SN74ACT573DWG4 is mainly composed of eight identical latches and each latch has the same configuration and performance. This latch has an eight-bit data line, which can be used to both store and output data. Furthermore, it has two enable inputs (G1 and G2) and eight complementary outputs to enable faster and more accurate data storage. The latch also features an independent reset input as well as an output enable: both of which significantly improve its performance in bus oriented systems.

The SN74ACT573DWG4 is capable of handling both positive and negative logic levels at frequencies of up to 7.5 MHz. Its output characteristics are TTL-compatible and the latch works at a temperature range of 0°C to 70°C. Its features make it a great choice for applications involving high switching speeds and a large amount of data communication operations.

The main feature of the SN74ACT573DWG4 latch is its working principle. In essence, this latch will store one digital state per latch: either a “high” or “low” state. This is accomplished by latching the output state of the data line when both of the enable inputs (G1 and G2) are held high. The stored state is maintained, unless one or both of the enable inputs is brought to a low state. This will, in turn, reset the stored latch state and causes the latch to either output a low signal or a high signal, depending on the input data. If the two inputs are both high, the latch will maintain and store the data, allowing for smooth data transfer between the source and latch.

In conclusion, the SN74ACT573DWG4 is a great choice for applications which require communication between a central source and multiple peripheral devices, or high switching speeds. With its combination of low power consumption, low propagation delay and retention capabilities, this device is exceptionally well suited for high speed digital system applications. The device’s eight-bit data line, two enable inputs and eight complementary outputs further enhance its usability in certain applications, making it a perfect choice for bus-oriented systems which require temporally stored data.
