The IC component 74ACT573PC is a octal D-type transparent latch with 3-state outputs that can operate within a wide range of 2.0V to 6.0V. It provides eight latch enable (LE) inputs to control the state of each latch, and eight separate data inputs (D0 to D7) for inputting data. The latched outputs, named Q0 to Q7, are available as 3-state outputs.
This device features several key characteristics that make it suitable for a variety of applications. Firstly, it operates at high speed, with a typical propagation delay of only 7.5ns. This allows for rapid data transfers and efficient processing. It also offers a substantial output drive capability, with the ability to sink and source up to 24mA. This enables it to drive highly capacitive loads or interface with other components without signal degradation.
One significant advantage of the 74ACT573PC is its 3-state outputs. This feature enables the outputs to be disabled, putting them into a high-impedance state (Z), which effectively disconnects them from the connected circuit. This is particularly useful when multiple devices are connected to a common data bus, as it allows for bus sharing and prevents contention issues.
Furthermore, this component is edge-triggered, meaning it only responds to changes in the latch enable (LE) inputs when there is a transition from either high-to-low or low-to-high
