The SN74ACT574PWG4 has a total of 20 pins. The pin configuration is as follows:
The SN74ACT574PWG4 is an octal D-type transparent latch that can store and output 8 bits of data. It features a high-speed operation and low-power consumption, making it suitable for various applications.
The latch has an output enable (OE) pin, which allows the user to control the output state. When OE is low, the latch is enabled, and the input data is transferred to the outputs. When OE is high, the outputs are in a high-impedance state.
The latch also has a master reset (MR) pin, which resets all the outputs to a low state when activated. This feature ensures a known initial state upon power-up or during system initialization.
Advantages: - High-speed operation - Low-power consumption - Octal configuration for storing and outputting 8 bits of data - Output enable and master reset functionality
Disadvantages: - Limited voltage range (2V to 6V) - Relatively small package size (TSSOP-20)
The SN74ACT574PWG4 operates based on the principles of flip-flops. It uses D-type transparent latches to store and output data. The latch is controlled by clock pulses (CP), which determine when the input data is transferred to the outputs.
When the CP signal transitions from low to high, the latch captures the data present at the inputs and holds it until the next clock pulse. The latch remains transparent during the high phase of the CP signal, allowing any changes in the input data to propagate to the outputs.
The output enable (OE) pin controls whether the latch's outputs are active or in a high-impedance state. When OE is low, the latch is enabled, and the stored data is available at the outputs. When OE is high, the outputs are effectively disconnected from the circuit, resulting in a high-impedance state.
The master reset (MR) pin allows the user to reset all the outputs to a low state. When MR is activated, all the outputs are forced to a low logic level, regardless of the input data or clock pulses.
The SN74ACT574PWG4 can be used in various applications that require the storage and output of 8 bits of data. Some potential application fields include:
