Product Description:

The SN74LV573ARGYRG4 features eight D-type latches with 3-state outputs designed to drive bus lines or buffer memory address registers. The device has a wide operating voltage range of 2 V to 5.5 V, which allows it to be used in various logic systems and makes it compatible with TTL levels.

Each latch is equipped with a 3-state output that can be placed in a high-impedance state, effectively disconnecting the output from the bus line. This feature is particularly useful in bus-oriented systems. The transparent nature of the latches means that while the latch-enable (LE) input is high, the Q outputs will follow the data (D) inputs. When LE is taken low, the Q outputs will be latched at the levels set up at the D inputs.

A clear (CLR) input is provided on the SN74LV573ARGYRG4, which when taken low, clears the latches immediately during any phase of the clock cycle, setting the outputs low. The robust design of this IC ensures that the outputs are in the high-impedance state during power up or power down, which prevents potential damage to connected components or bus systems.

Enclosed in a compact VQFN-20 package, the SN74LV573ARGYRG4 is designed for space-constrained applications while providing the reliability and performance expected from Texas Instruments products.
