The SN74LVTH240PWR is a type of integrated circuit used in the fields of electronics and telecommunication. It belongs to a family of logic-buffers, drivers, receivers and transceivers, and it has similar characteristics to its predecessor, the SN74LVTH240. The SN74LVTH240PWR has its own distinct features, including improved specifications and performances. Understanding the purpose and workings of this device helps to optimize its performance.

Application Field

The SN74LVTH240PWR integrated circuit is widely used in various communication and data transmission applications, including high-speed serial links, such as Gigabit Ethernet, USB 2.0, SATA, and the like. It is also suitable for bus systems with either one or two clocks, such as I2C, SPI, and PCI. This device is capable of data transfer at speeds up to 3.2 Gb/s. It is used in automotive infotainment systems, computer peripherals, digital point-of-sale systems, as well as many other digital and telecom applications.

Working Principle

The SN74LVTH240PWR consists of a low-voltage differential signaling (LVDS) receiver and 4 LVDS drivers. The receiver and the LVDS drivers are located on the same integrated circuit and are powered by a single supply. At the receiver side, the differential input is converted to singleended output, which is then applied to the respective LVDS driver. The LVDS driver is an output-buffer with a pair of complementary outputs that generate differential signals with a voltage range between 0.2 and 2.8 V.

The differential signals are transmitted to the receiver, where they are once again converted to single-ended output before being passed onto its respective driver. The LVDS receiver also features a slew-rate limiter that helps to minimize EMI emission, while the other components of the SN74LVTH240PWR enable adaptive de-skewing that allows the device to adjust the clock skew automatically without any user intervention.

The device also has two output-enable pins, two input pins, and a power-down pin. The two output-enable pins allow the users to disable the outputs as required, while the two input pins give users the ability to externally configure the receiver for either a double-bit-clock or a single-bit-clock architecture. The power-down pin helps to reduce the device\'s power consumption when not in use.

Features

The primary features of the SN74LVTH240PWR include: low power consumption, wide input voltage range of 1.0V to 3.3V, improved control capability, integrated EMI reduction circuitry, automatic clock-skew adjustment, and an ultra-low quiescent current level. The device also has an inherent 7-bit per character data delimiter, which helps to limit the data transmission rate in applications with high-frequency buses.

Aside from its improved specifications and performances, the SN74LVTH240PWR\'s EMI reduction capabilities are an important feature that make it suitable for high-speed serial link applications. The built-in EMI circuitry helps to reduce electromagnetic interference, thereby improving signal integrity and data transmission rates. Additionally, this device is equipped with an internal voltage regulator, which enables it to operate with a single supply voltage making it both cost-effective and energy-efficient.

Conclusion

The SN74LVTH240PWR is a type of integrated circuit belonging to the logic-buffers, drivers, receivers, and transceivers family. It is optimized for high-speed serial link applications, and features improved specifications and performance capabilities. This device is designed for low power consumption, wide input voltage range, EMI reduction circuitry, and an internal voltage regulator. Finally, its adaptive de-skewing feature helps to keep the clock skew at minimum, thereby improving the signal integrity and transmission rates.
