Logic translators and level shifters have become increasingly important components in the design of electronic circuits. These devices allow the integration of logic signals between circuits operating with different logic levels. SN74GTLPH1627DGGR is a logic translator and level shifter that provides bidirectional voltage translation and signal level shifting between two different supply voltages VL, VH without the use of external components. This device features two low VOH outputs and one high VIH output to provide bidirectional translation from one device family to another.

The SN74GTLPH1627DGGRis an automotive high-speed quad-channel logic translator and level shifter for bus protocols such as CAN FD and LIN. This device is designed to bridge the logic signal level gap between two different device families by providing the ability for bidirectional signal differential transmission and conversion between two different power domain voltages.

The SN74GTLPH1627DGGR consists of four separate channels and each channel can be powered by different supply voltages. Each channel provides bidirectional voltage translation between two different voltage levels. The differential output driver can deliver 350 μA over a rail-to-rail voltage range. Output levels are configurable and programmable using external pullup and pull down resistors. The output of each channel is enabled by an independent enable signal. The SN74GTLPH1627DGGR utilizes ESD protection that eliminates external ESD diodes.

The SN74GTLPH1627DGGR operates in two modes: active-low mode and active-high mode. In active-low mode, the output driver is enabled when the enable input is logic low. In active-high mode, the output driver is enabled when the enable input is logic high. The enable time of the output driver is approximately 10 ns. The SN74GTLPH1627DGGR can be switched from active-low mode to active-high mode by setting the enable pin to the respective voltage level, ensuring a voltage and level change can happen almost simultaneously.

The working of SN74GTLPH1627DGGRis simple and it directly translates the logic level from one voltage level to another. The translation voltage of each channel is programmable with external resistors. This device can be used in multiple applications including automotive interfaces, multi-channel CAN FD, LIN in-vehicle–networks, industrial networks and more. Its low power consumption makes it suitable for battery powered applications.

In summary, SN74GTLPH1627DGGR is a quad channel logic translator and level shifter that provides a bidirectional, voltage translation between two different device families or a supply voltages. This device has a wide range of applications due to its low power consumption, fast switching time and wide voltage range. Its low power consumption makes it suitable for use in battery powered applications.
