Dual Buffer, Open Drain

The NL27WZ07 is a high performance dual Buffer with open drain outputs operating from a 1.65 to 5.5 V supply. The internal circuit is composed of multiple stages, including an open drain output which provides the capability to set output switching level. This allows the NL27WZ07 to be used to Interface 2 circuits to circuits of any voltage between VCC and 7 V using an external resistor and power supply.
