ON Semiconductor MC74HC573ADTR2 Octal 3-State Non-Inverting Latch

The ON Semiconductor MC74HC573ADTR2 is a high-performance, octal 3-state non-inverting latch integrated circuit designed for use in a wide range of digital applications. This device is part of the high-speed CMOS HC family and offers a robust latch function with eight latches in a single package, making it ideal for interfacing with bus-oriented systems.

The MC74HC573ADTR2 features eight latches with three-state outputs for bus organized system applications. The device has a 2-input enable structure that can either disable the device so that the outputs are effectively in a high-impedance state or enable the device, allowing the latches to store the information present on the inputs. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs.

A notable feature of this device is its high noise immunity characteristic of CMOS devices. The MC74HC573ADTR2 operates at a voltage range of 2V to 6V, providing a flexible power supply range suitable for various applications. This wide operating voltage range also makes the device compatible with TTL levels, ensuring easy integration into mixed-voltage systems.

The output drive capability of the MC74HC573ADTR2 is impressive, with the ability to drive up to 15 LSTTL loads. This makes it suitable for driving heavy loads or for use in environments where signal integrity can be challenged by long cables or demanding interfacing conditions.

Furthermore, the MC74HC573ADTR2 device comes in a TSSOP-20 package, which is a space-saving option for PCB designs. The small footprint of the TSSOP package allows for a more compact design, enabling the creation of smaller and more efficient electronic devices.

In summary, the ON Semiconductor MC74HC573ADTR2 is a versatile and reliable octal latch that provides high-speed operation, low power consumption, and stable performance, making it an excellent choice for a broad array of digital applications, from data bus interfacing to signal buffering.
