Working Principles

The CY74FCT16543ATPACT is a 16-bit transparent latch/flip-flop integrated circuit. It can store and transfer digital data using its 16 input pins (D0-D15) and provide the output on corresponding pins (Q0-Q15). The latch enable (LE) signal controls the latching of input data, while the output enable (OE) signal enables or disables the output buffers.

When the latch enable signal is active, the input data is latched and stored in the internal memory. The output enable signal determines whether the output buffers are enabled or disabled. When the output enable signal is active, the stored data is available at the output pins. Otherwise, the outputs are in a high-impedance state.

The CY74FCT16543ATPACT operates on a clock signal (CLK) that synchronizes the data transfer. On each rising edge of the clock signal, the input data is sampled and latched. The latched data remains stable until the next clock cycle.

Detailed Application Field Plans

The CY74FCT16543ATPACT can be used in various applications that require data storage and transfer, such as:

1. Microprocessor-based systems
2. Data communication equipment
3. Industrial control systems
4. Instrumentation and measurement devices
5. Automotive electronics
6. Consumer electronics

Its high-speed operation, low power consumption, and compatibility with TTL and CMOS logic levels make it suitable for these applications.
