Product Overview: 74LVC573AQ20-13 from Diodes Incorporated

The 74LVC573AQ20-13 is a high-performance, octal D-type transparent latch from Diodes Incorporated, designed to be a part of the advanced 74LVC family. This integrated circuit is tailored for low-voltage operation, making it suitable for systems that require efficient power consumption without compromising on speed and performance. It is particularly well-suited for interfacing with 3.3V and 5V systems, thanks to its wide range of operating voltages.

One of the key features of the 74LVC573AQ20-13 is its 5V tolerant inputs, which allow for direct interfacing with 5V TTL logic levels without the need for external components. This feature simplifies design and reduces overall system cost. Additionally, the device has a high noise immunity, ensuring stable operation even in electrically noisy environments.

The latch operates as a transparent D-type latch during normal operation, with data at its inputs appearing at the outputs as long as the Latch Enable (LE) input is held high. When LE is taken low, the data at the outputs is latched and remains unchanged until LE is returned high. This functionality is essential for systems that require data to be captured and held stable for a certain period.

Furthermore, the 74LVC573AQ20-13 boasts a high drive capability, with the ability to drive up to 24mA at the outputs. This makes it capable of driving heavier loads than standard CMOS outputs. The device also features a bus-hold function, which maintains the last output state when the input is not actively driven, thus preventing floating inputs and reducing the risk of erratic system behavior.

Offered in a 20-pin TSSOP package, the 74LVC573AQ20-13 is designed to occupy minimal space on a PCB, making it an ideal choice for space-constrained applications. This product is also characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide temperature range, which is critical for industrial and automotive applications.

In summary, the 74LVC573AQ20-13 from Diodes Incorporated is a versatile and robust component that provides reliable latching functionality for a variety of digital applications, ensuring data integrity and system stability in a compact and power-efficient package.
