SN74LVCC3245ANSR application field and working principleThe Texas Instruments SN74LVCC3245ANSR is a low voltage CMOS integrated circuit (IC) level translator. This device helps users bridge the logic voltage gaps between various logic levels. SN74LVCC3245ANSR is supported by both 3.3V and 5V logic supply levels, and it can effectively interconnect two different logic class connections.The SN74LVCC3245ANSR belongs to the Texas Instruments SN74LVCC307x family of Logic-Translators, Level-Shifters and Buffer products. This dual-voltage level translators provide a solution for bridging voltage level mismatches between a 3.3V and 5V logic domain. The SN74LVCC3245ANSR also provides two independent circuits for accurate bus translation. The SN74LVCC307x device family’s high level of integration, power efficiency, and number of I/O components makes it a perfect choice for applications such as board level bridging to interface a 3.3V system to a 5V one or for interfacing an ASIC with a low voltage logic device.The SN74LVCC3245ANSR utilizes the receiver and driver technology to enable fast data translation between a 3.3V and a 5V logic interface. It includes two independent translation channels which enable efficient bus translation. The receiver functions of the SN74LVCC3245ANSR implement adjustable threshold and active pullup while the drivers section of the chip implements active pull-down circuitry. As a result, the device supports point-to-point, daisy chain, and up to four TTL loads.The SN74LVCC3245ANSR operates over a temperature range of -40 to +85°C (-40 to +185°F) and maximum supply voltage of 3.6V and 5.5V. This level translator is mainly used for communications, industrial, medical, automotive and consumer applications. This level translator has a host of features that make it an ideal addition to any system. The SN74LVCC3245ANSR utilizes a non-inverting buffer/inverter with open-drain outputs which helps it provide fast communication between multiple voltage domains. Furthermore, its low power and low voltage characteristics make it energy efficient and help to reduce power consumption. Additionally, the SN74LVCC3245ANSR includes active pull-up and pull-down circuitry, which helps to minimize noise due to random or external data transitions, and helps to maintain high signal integrity.The SN74LVCC3245ANSR working principle is based on the receiver and driver technology. When an input signal is applied to the receiver section, the threshold voltage of the receiver is compared to the voltage level of that signal. If the signal voltage level is higher than the threshold voltage, then the receiver output is driven high, which then enables the driver circuit, allowing the driver to switch the output signal as low as possible, usually under 0.8V. Conversely, when an input signal is applied to the receiver section, if the signal voltage level is below the threshold voltage of the receiver, then the receiver output is driven low, meaning the driver will not switch the output and the output signal will remain low.The SN74LVCC3245ANSR level translator is the ideal choice for bridging the gap between the various logic level domains. Thanks to its features like active pull-up and pull-down, fast data transmission, low power consumption, wide temperature range and adaptability to various applications, it can provide great connection reliability and accuracy. Therefore, it is the perfect solution for bridging between a 3.3V and a 5V logic interface.
