Introduction

SN74AUC1G17DCKR is a monolithic driver / receiver transfer functional integrated circuit, which belongs to the family of Texas Instruments Logic series. This integrated circuit has wide application field, including communication systems, audio systems and video systems, etc, and delivers better communication interface speed, as well as higher current drive and lower power consumption.

Application field

SN74AUC1G17DCKR is typically used as line drivers, receivers or transceivers in communications systems, audio systems, video systems and other digital systems, especially in applications which require conversion of TTL (Transistor-Transistor Logic) levels to and from RS-232, RS-422 and RS-485 levels.This integrated circuit has two receivers and one driver, along with a built-in ESD (electro-static discharge) and EMI (electro-magnetic interference) protection mechanism, which can protect itself from destructive voltage and current, as well as the interfaces connected to it. Its integrated level-shifter control gates can convert TTL level input to and from higher voltage levels, like RS-232, RS-422 and RS-485.

Working Principle

SN74AUC1G17DCKR has two enable inputs, ENBA and ENAA, and one direction control input, STB. All these three inputs are active-low, which should be connected to TTL compatible signals in order to achieve proper level shifting and current drive.ENAA is the receiver control input. With the application of high level signal to this input, it will cause the first receivers connected to RXA1 and RXA2 logic pins to be enabled, enabling transmission of data from the devices connected to these two logic pins. In this case, the logic pin RxA2 is normally used as the inverted version of the logical signal received from a connected device.ENBA and STB are respectively used to control the built-in driver, which is connected to DVOUT logic pin. The ENBA input is for driver control and should be connected to a TTL logic signal, so that the application of a high level signal will enable the driver, driving the output of DVOUT to the levels determined by STB input. When the STB input is connected to a high level signal, the driver of integrated circuit will begin to output the data received by its two receivers.

Conclusion

SN74AUC1G17DCKR is a useful monolithic driver / receiver transfer function integrated circuit, widely used in communication systems, audio systems and video systems, etc. Its built-in ESD and EMI protection mechanism, along with its level-shifter control gates make it perfectly capable to convert TTL level input to and from higher voltage levels, such as RS-232, RS-422 and RS-485. Plus, its two enable inputs, ENBA and ENAA, and one direction control input, STB provide maximum flexibility and convenience in controlling transmission. With all these features put together, SN74AUC1G17DCKR surely forms an reliable and efficient logic buffer for different digital applications.
