SN74AS573ADW

Logic - Latches

The SN74AS573ADW is a high-speed, low-power, 8-bit latch circuit. This type of device is commonly referred to as a data register, and its primary function is to ensure the safe transport of digital data. The SN74AS573ADW operates at operating voltages between 2.5 V and 5.5 V, and is designed to perform in an environment that’s exposed to a wide range of temperatures (-55°C to 125°C). It’s also characterized by its hot-swap allows feature, which ensures connections don’t get disrupted while the device is being replaced, and its even power-on reset feature.

Application Field

The SN74AS573ADW can be broadly classified into two distinct application fields. It’s typically used in consumer electronic equipment, like digital televisions, high-definition video gaming systems, and audio players. The SN74AS573ADW can also be used in industrial applications, such as motor controllers, automotive diagnostics systems, and other areas that require reliable long-term data storage.

Working Principle

The SN74AS573ADW can be described as consisting of two components: a storage part, and an input/output (IO) part. The storage part consists of eight flip-flop registers, which each store one bit of data, and a parity bit register, which provides an extra bit of data protection. The IO part provides the necessary IO ports, which allow the device to be connected to external circuits.

The operation of the SN74AS573ADW is quite simple. When the latch is at a low voltage, the data stored in the registers is clocked in (i.e. transferred to other registers). Once the latch is set to a high voltage, the data is held within the register until it is clocked out. By alternating these two voltage states, data can be copied from one register to another or from the IO ports to a register, allowing for reliable and accurate data handling.

The SN74AS573ADW is an incredibly useful device for a wide range of applications that require reliable data handling. Its low-power operation, wide operating temperature window and hot-swap allows feature makes it the perfect choice for many applications.
