The 74FCT543ATQG belongs to the category of integrated circuits (ICs) and specifically falls under the group of octal transparent latches with 3-state outputs.
This product is commonly used in digital systems for data storage and transfer. It serves as a latch, allowing the temporary storage of data before it is transferred to other components or processed further.
This IC is available in a standard 20-pin TSSOP (Thin Shrink Small Outline Package) package. It is typically sold in reels containing a quantity of 250 units.
The 74FCT543ATQG has a total of 20 pins, which are assigned specific functions as follows:
The 74FCT543ATQG operates based on the principle of transparent latching. When the latch enable (LE) input is high, the data inputs (D0-D7) are directly connected to the outputs (Q0-Q6). This allows the data to pass through the IC without any delay.
The clock input (CLK) triggers the latching action. On the rising edge of the clock signal, the data present at the inputs is captured and stored in the internal storage elements. The stored data remains unchanged until the next rising edge of the clock.
The output enable (OE) input controls the state of the outputs. When OE is low, the stored data is available at the outputs. Conversely, when OE is high, the outputs enter a high-impedance state, effectively disconnecting them from the external circuitry.
The 74FCT543ATQG finds applications in various digital systems where data storage and transfer are essential. Some potential application fields include:
