Logic translators, level shifters and the NB6L16DR2G in particular are types of electronic circuits responsible for interfacing devices operating at different logic or supply levels. As a level shifter, the NB6L16DR2G provides level shifting for two bi-directional channels between two nodes.

Built around Fairchild Semiconductor’s low-voltage I/O technology, the NB6L16DR2G operates at voltages between 2.0V to 3.6V. Its top level speeds up to 25 MHz and bottom level speeds up to 16 MHz. It features Schmitt Triggers input stages and it is characterized for thermal, ESD and latch-up immunity.

The NB6L16DR2G is a logic level shifter suitable for portable and battery powered applications that, due to their power consumption requirements, need to function in a low-voltage environment. These devices allow for the successful connection and translation of logic signals between the two levels on each input/output channel, guaranteeing the integrity of the signal flow with low propagation delay, low noise and low power consumption.

The main application field of the NB6L16DR2G is related to low-voltage wireless communications devices, such as portable cell phones, wireless modems, and WLAN applications, wherever the combination of dual level-shifting channels are required. The level-shifting circuits in these devices have to convert and translate logic signals between the high voltage of the communications module, like the baseband processor, to the supply/output level of the microcontroller and vice versa.

The NB6L16DR2G is an excellent combination of level shifter and protective circuit. Built-in ESD protection circuitry ensures the safety of the VCC, GND, and inputs from the human body electrostatic discharges. It also features an auto-restore circuit, which is designed to reset the circuitry after a latch-up event.

The NB6L16DR2G is built upon Fairchild Advanced CMOS technology, which ensures low power and low noise performance. The logic level shifter also features Schmitt Trigger input stages and CMOS outputs, enabling high speed and noise immunity data synthesis. LVTTL outputs incorporate resistance to spositive and negative transients of up to 15KV and 10KV, respectively.

The device is available in a space-saving 4-pin SOT-23 package, with a power-on-reset pin configured as an active low reset and an enable pin active high. Power-on reset pulls down a digital output while power is being supplied, and the EN pin prevents the outputs from changing states. Power supply lockout feature limits the power dissipation during logical mis-operation or interface mismatch.

The NB6L16DR2G is a great logic level shifter for low-voltage, low-power systems due to its small form factor, low voltage operation, low power consumption, and immunity to ESD, latch-up and thermal events. It is a reliable choice for wireless communication systems and any other application where level shifting from one voltage to another is needed.
