Logic - Latches - SN74ALS990DW
The SN74ALS990DW is an integrated circuit from Texas Instruments that was designed for applications such as synchronous entrance and output latch, edge triggered latch, or both. An integrated circuit is an integrated circuit that includes the larger, discrete circuit components and their related circuitry to perform a specific set of tasks.
The SN74ALS990DW is classified as a logic latch, which are electronic devices that are used to store state in an electronically controlled system. A logic latch can either be set or reset depending on the inputs it receives. In the case of the SN74ALS990DW, it is designed as an edge triggered latch, meaning that the device will be triggered when a logical transition is made, such as the transition from low to high. This type of latch is useful because, unlike other latching devices, the state will remain even if the input signal is removed.
The SN74ALS990DW is a 16-bit latch that consists of four separate integrated circuits. It is also available in 8-bit and 10-bit versions. Each IC contains four latches, and each latch has a control, a data input, and a data output. Every latch is edge triggered and can be configured to either latch on the rising edge or the falling edge of the clock. Additionally, it can be used as a synchronous entrance and/or output latch and/or an asynchronously clocked latch. The combination of these features makes the SN74ALS990DW, a very versatile device.
The SN74ALS990DW is suitable for applications where it is necessary to store large amounts of data in a very compact package, or for applications where speed and reactivity are paramount. One example is when designing memory interfaces. The SN74ALS990DW is ideal for applications such as this, as it can be configured to act as a synchronous or asynchronous latch or both. Furthermore, it has the advantage of being able to latch on both the rising edge and falling edge of the clock. This means that data can be latched faster and for longer durations.
Another application for the SN74ALS990DW is in synchronous systems. The latch can be used to trigger an event, such as starting a motor, when the logic level of an input signal changes. The SN74ALS990DW will hold the state of the output until it is reset, ensuring that the desired reaction is always triggered.
The SN74ALS990DW is well suited for many logic isolator applications. It’s low propagation delay, small footprint and low power consumption make it an ideal choice for power-sensitive designs. Additionally, the device\'s pin-to-pin compatibility makes it a drop-in solution for many digital isolator designs.
Overall, the SN74ALS990DW is a highly versatile and reliable device. Its ability to act as a asynchronous or synchronous latch, configure for rising edge or falling edge triggering, and its small package make it an ideal choice for many applications. Its low power consumption and the wide range of applications it can be used for make it an easy choice for many design engineers.
