NXB Series Voltage Translators

Nexperia's family of 1-, 2-, 4-, and 8-bit dual-supply translating transceivers have auto-directional sensing. Autosense translation can be used in both push-pull and open-drain based applications without additional directional pins. It features two 1-bit, 2-bit, 4-bit, or 8-bit input-output ports (A and B), one output enable input (OE), and two supply pins (V_CC(A) and V_CC(B)). V_CC(A) can be supplied at any voltage between 1.65 V and 3.6 V and V_CC(B) can be supplied at any voltage between 2.3 V and 5.5 V, making the device suitable for translating between any of the voltage nodes (1.8 V, 2.5 V, 3.3 V, and 5.0 V). Pins An and OE are referenced to V_CC(A) and pins Bn are referenced to V_CC(B). A LOW level at pin OE causes the outputs to assume a high-impedance OFF-state. This device is fully specified for partial power-down applications using I_OFF. The I_OFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
