ON Semiconductor MC74HC573ADT Octal Latch

The MC74HC573ADT is a high-performance integrated circuit produced by ON Semiconductor, a leader in energy-efficient innovations. This particular device belongs to the 74HC series, which is well-known for its high-speed CMOS technology. The MC74HC573ADT is an octal transparent latch with three-state outputs, making it an essential component for temporary storage of data in a wide range of digital systems.

Designed to operate as an eight-bit latch, the MC74HC573ADT features eight latches with three-state standard outputs. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. If LE is low, the Q outputs are latched at the levels set up at the D inputs. A separate output enable (OE) input puts the eight outputs in either a normal logic state (high or low logic levels) or in a high-impedance state. In the latter state, the outputs neither load nor drive the bus lines significantly, which is ideal for bus-oriented systems.

The device is characterized for operation from -55°C to 125°C, ensuring reliable performance across a wide range of environmental conditions. The MC74HC573ADT is provided in a TSSOP-20 package, which is perfect for applications where space is at a premium. Its pinout is arranged for convenient PCB layout, with all inputs and outputs located near the edge of the device for easy access.

With a typical latch-up performance of 250 mA, the MC74HC573ADT is also latch-up performance exceeds 100 mA per JESD 78, Class II. This robustness makes it suitable for the demands of various applications, including industrial control systems, communication equipment, data processing, and consumer electronics.

Overall, the ON Semiconductor MC74HC573ADT is a versatile and reliable component that provides a secure way to store data and an effective method to manage bus systems within a circuit. Its high-speed performance, coupled with low power consumption, makes it an excellent choice for designers looking for a dependable octal latch solution.
