The 74FCT162952ATPACT is a high-speed, low-power logic-level translater housed in a small MSOP-10 package and is ideal for mobile applications. This integrated circuit is used for logic-level bi-directional conversion and signal translation between two independent power domains. It is designed to interface between any CMOS, TTL or LVTTL outputs and any dual-supply power domain.

Application Field

The 74FCT162952ATPACT is a logic-level translator that is well suited for applications that require signal translation between two different power domains. It has a wide frequency range of 1 MHz to 400 MHz and the translator enhances system performance by eliminating the need for buffers and interface logic, enabling longer communication and data transfer distances. The low power consumption of the chip makes it well suited for battery operated and mobile applications, while its low skew features makes it a great choice for applications where signals need to be sampled and retransmitted or multiplexed. The chip also combines low propagation delay, low noise and low energy dissipation, making it suitable for a wide range of communications protocols such as 1 Mbps to 10 Gbps Ethernet, 2G, 3G and 4G wireless, Fibre Channel and PCI Express serial bus.

Working Principle

The 74FCT162952ATPACT is based on a configurable dual-power-domain modulation technique that enables bi-directional signal translation between a TTL, CMOS or LVTTL output and either dual 3.3V or dual 5V power supplies. The inputs and outputs of the integrated circuit can be configured to support any voltage from 2.5V to 5.5V, making it easy to interface with different logic levels. By using the two available power levels, the integrated circuit can support any combination of power domains.

The integrated circuit can be used for bi-directional signal translation in various applications. In unidirectional applications, it works by translating a low voltage input to a high voltage output or vice versa. In bidirectional applications, the integrated circuit translates the signal in both directions, allowing data to be transmitted over longer distances while still retaining its quality and integrity.

The integrated circuit also includes accurate data transmission and protection features. Its automatic cold detection and power-on reset functionality guarantee that the system will always be powered up properly. Its Receiver Input Amplitude and Rise/Fall Times features maximize the data transmission accuracy by providing reliable signal level thresholds and rise/fall times. Its TruOutput Open-Drain Mode allows for the connection of multiple logic levels and multiple power domains and provides additional electrical noise shielding.

Conclusion

The 74FCT162952ATPACT is a versatile logic-level translator that is well suited for applications that require signal translation between two different power domains. Its low power consumption and low skew features make it an ideal choice for data transmission and noise shielding applications. Its wide range of support makes it compatible with all types of logic level and power domain, making it the perfect choice for a wide range of communications and data transfer applications.
