ON Semiconductor MC74AC573DTR2 Octal Latch

The ON Semiconductor MC74AC573DTR2 is a high-performance, octal transparent latch integrated circuit, designed to provide a robust and reliable solution for digital storage applications. This device is part of the advanced high-speed CMOS family and is capable of operating at significant speeds while maintaining low power consumption.

With its 20-lead TSSOP package, the MC74AC573DTR2 offers a compact footprint suitable for space-constrained applications. The latch is equipped with eight latches with three-state outputs, making it an ideal choice for interface applications where high drive capability is necessary. These outputs can drive loads with up to 15 LSTTL loads, ensuring compatibility with various logic families.

The MC74AC573DTR2 operates over a wide voltage range of 2V to 6V, providing flexibility in different system voltages and ensuring compatibility with a broad range of digital systems. This feature is particularly important in mixed-voltage environments, where the device can interface with other logic levels seamlessly.

Each latch has a dedicated data input (D) and output enable (OE) control, which ensures precise control over the flow of data. When the output enable (OE) input is high, the outputs are in a high-impedance state, which effectively isolates the latches. This is particularly useful in bus-oriented systems where multiple devices need to share common data lines without interference.

The transparent nature of the latch allows data at the inputs to appear at the outputs as long as the latch-enable (LE) input is held high. A low on LE latches the data present at the D inputs, capturing and holding that data for future use. This feature is critical in timing-sensitive applications where data must be captured and synchronized with other system events.

Manufactured with ON Semiconductor's commitment to quality and reliability, the MC74AC573DTR2 is a versatile component that enhances the performance and efficiency of digital systems. Its fast switching speeds, low power dissipation, and robust latch function make it a go-to solution for designers looking to improve data handling in their digital applications.

Whether used in communication systems, computers, data processors, or other high-speed logic applications, the ON Semiconductor MC74AC573DTR2 offers a perfect blend of speed, power efficiency, and functional versatility.
