ON Semiconductor MC74HC573ADWR2G Octal 3-State Non-Inverting Latch

The MC74HC573ADWR2G is a high-performance integrated circuit manufactured by ON Semiconductor, renowned for its precision and durability in various electronic applications. This octal 3-state non-inverting latch is part of the high-speed CMOS family, designed to operate with the same speed as LSTTL while maintaining the CMOS low power dissipation.

This device consists of eight latches with three-state outputs for bus organized systems applications. It is typically used for temporary storage of data, and it can hold eight bits of information. The transparent latch allows data to flow from input to output when the Latch Enable (LE) pin is held high and 'latches' the data when LE is taken low. The output will retain the value even when the input is no longer present, making it an essential component for data storage and signal buffering.

The 3-state outputs (nQ) are controlled by the Output Enable (OE) input. When the OE is low, the outputs are active and reflect the data that is latched. When OE is high, the outputs are in a high impedance state, which effectively isolates the outputs from the bus. This feature allows for multiple devices to be connected to the same bus line without interference, making the MC74HC573ADWR2G ideal for bus interface and memory address driving where high sink current capability is required.

Key features of the MC74HC573ADWR2G include:

• Compatible with MC74HC573A
