SN65LBC172AN

The SN65LBC172AN is an interface driver, receiver, and transceiver designed to provide voltage-level shifting between various logic families, such as CMOS and TTL. It is commonly used to drive a logic signal across circuits where the voltage levels are not compatible.

The device contains two sets of inputs and outputs – one set is used to drive a logic signal and the other set is used to receive the signal. Therefore, the SN65LBC172AN acts as a buffer, allowing logic level shifting without the need for external logic gates. Additionally, the device utilizes bidirectional communication, allowing for the transmission of both input and output signals.

The SN65LBC172AN is a complementary metal-oxide semiconductor (CMOS) that is characterized by its extremely low power consumption and exceptional noise immunity. The device is typically housed in a 16-pin dual in-line package and has a 0.8-volt to 5-volt voltage range.

In terms of operation, the SN65LBC172AN drives a logic signal (high or low) from one voltage level to a different voltage level. The device has the capability to convert a logic signal from one logic family to another. For example, a TTL output can be converted to an open collector output, or a CMOS output can be converted to a TTL output.

The SN65LBC172AN also provides level shifting by driving a level to the specified voltage, which is additionally useful in logic family-to-logic family conversions. The device is equipped with an open-collector output, allowing it to be connected directly to the output of another circuit. Using a shorted output-to-ground connection, the AN will drive the signal at the specified voltage.

Additional features of the SN65LBC172AN include the ability to drive a logic signal from one voltage level to a different voltage level without the need for external logic gates and its capability to function as an interface for a variety of logic families (CMOS, TTL, etc.). The device is also equipped with an over current and over voltage protection, which helps protect against any accidental damage.

Overall, the SN65LBC172AN is a low power and noise-resistant interface driver, receiver, and transceiver that is designed to provide voltage-level shifting between various logic families. The device is useful in applications that require the conversion of logic signals from one logic family to another, or the level shifting of a signal to a specified voltage level.
