SN74LVC573ADWR Integrated Circuits (ICs)

SN74LVC573ADWR is a CMOS automotive, high-temperature, octal D-type transparent latch. It handels data in 8-bit bytes and can latch the data on a rising- or falling-edge signal. The SN74LVC573ADWR is characterized for operation from -40oC to 85oC.

Application Field

The SN74LVC573ADWR can be used in various automotive usage applications like motor control, HVAC, safety, backward compatibility etc. This is a highly featured device which helps in tuning data on buses to earlier systems and also supports storage of data during power failure. This feature helps to decrease the total energy requirement and hence improves overall efficiency. This is suitable for applications that require data transfer through CAN, CAN FD or power management applications.

Working Principle

The SN74LVC573ADWR latch works on 8 data lines and 1 enalbe signal. It has two modes, 3-state, and non-3 state mode. If a byte of data presented to the D-inputs as a binary number and then a rising/falling edge signal is applied to the Enable input, the data is latched into the latch. In 3-state mode, the latched data is presented onto the differential outputs for use by other devices. In non-3 state mode, the latched data appears on the output in the same way as it enters.

In the SN74LVC573ADWR latch, data enters the latch on a rising/falling edge of the enable signal and the data is stored in memory. When power is removed, the data is safely stored in the built-in registers, so that when power is reapplied the data that was stored in memory will be the same as before. It is also capable of generating the inversion logic or non-inversion logic of the latched data.

The SN74LVC573ADWR is also capable of generating multiple internal interrupts for event-driven processing. When an input data is latched, an interrupt is generated in order to successfully resolve the task without any polling delays.

Conclusion

The SN74LVC573ADWR is a CMOS automotive, high-temperature, octal D-type transparent latch. It handels data in 8-bit bytes and can latch the data. This latch is suitable for applications that require data transfer through CAN, CAN FD or power management applications. It is also capable of generating multiple internal interrupts for event-driven processing, and comes with the added feature of being able to store data during power failure.
