ON Semiconductor MC74VHCT573ADWR2 Octal D-Type Latch

The MC74VHCT573ADWR2 is a high-performance, octal D-type latch designed by ON Semiconductor, a leader in energy-efficient innovations in power and signal management. This integrated circuit is part of the VHCT family and is engineered to interface between two different voltage domains, making it an ideal component for systems that require level shifting or voltage translation functionalities.

Constructed with advanced silicon-gate CMOS technology, the MC74VHCT573ADWR2 offers robust performance with high noise immunity and low power consumption. The device features eight D-type latches with 3-state non-inverting outputs, which allow for bus-oriented applications. 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 significant advantage of this latch is its ability to operate with a wide range of supply voltages, from 4.5V to 5.5V, while maintaining compatibility with TTL input and output voltage levels. The MC74VHCT573ADWR2 also supports a high fan-out capacity, enabling it to drive multiple loads without significant performance degradation.

The device comes in a surface-mount, 20-lead SOIC package (suffix DW), which is designed for space-saving applications and ensures a compact footprint on printed circuit boards. Additionally, the MC74VHCT573ADWR2 is characterized for operation from -55°C to +125°C, making it suitable for use in a wide range of industrial and automotive environments where temperature extremes are common.

Key features of the MC74VHCT573ADWR2 include:

• High-speed CMOS technology
• Octal D-type latches with 3-state outputs
• Wide operating voltage range of 4.5V to 5.5V
• TTL-compatible input and output levels
