The CY74FCT16501ATPVCT is a member of Cypress’s FCT family of UDL low voltage advanced CMOS logic devices. It is a universal bus function device, designed to give designers the flexibility to capture and retransmit data across an advanced system bus. The CY74FCT16501ATPVCT offers very low power and is available in a variety of package options.

The application and working principle of the CY74FCT16501ATPVCT can be divided into two categories:

Bus Transceiver

The CY74FCT16501ATPVCT serves as a transceiver for the bus. It has two independent logic channels, allowing it to receive data from one bus and transmit the same signals on another bus, or vice versa. The logic levels and timing of each of the two buses can be independently adjusted, which allows designers to accommodate different standards and spacing among the buses.

The CY74FCT16501ATPVCT includes two input/output (I/O) ports, each of which is connected to two buses. The two ports provide separate I/O pins for each bus, along with dedicated control signals and pin enable switches, enabling the CY74FCT16501ATPVCT to function as a bidirectional bus transceiver⁠—able to receive data from one bus and transmit it on the other. The CY74FCT16501ATPVCT also has an asynchronous common mode reset with a delay feature that allows for a controlled reset of the device and provides enhanced flexibility for high speed applications. In addition, the CY74FCT16501ATPVCT has a power-down feature to reduce power consumption during inactive periods.

Active Bus Termination

The CY74FCT16501ATPVCT also enables active termination of the buses, which can reduce signal reflection caused by signal reflection at the end of the line, and therefore reduce signal jitter and improve signal integrity. The termination feature of the CY74FCT16501ATPVCT is enabled or disabled through a dedicated pin control signal. When the signal is disabled, the active termination is turned off, minimizing power consumption. When the signal is enabled, the active termination circuit is activated and provides improved signal integrity and minimized jitter.

The CY74FCT16501ATPVCT is an efficient and versatile universal bus function device that allows engineers to build reliable and cost-effective systems. With its built-in bidirectional bus transceiver and active bus termination features, the CY74FCT16501ATPVCT is the ideal solution for designers looking for a flexible device for advanced system busses.
