RTC clock synchronization buffer driver delay chip

Low-power real-time clock chip with trickle current charging capability Real-time clock chip

The NL27WZ07 is a high-performance double buffer with open-drain output that operates from 1.65 V to 5.5 V. The internal circuitry consists of multiple stages, including an open-drain output that provides the ability to set the output switching level. This allows the NL27WZ07 to be used to interface 2 circuits with voltages between VCC and 7 V through external resistors and power supplies.
