1. General description
The NTB0102 is a 2-bit, dual supply translating transceiver with auto direction sensing,
that enables bidirectional voltage level translation. It features two 2-bit input-output ports
(An and Bn), 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 1.2 V and 3.6 V and V_CC(B) can be supplied at any
voltage between 1.65 V and 5.5 V, making the device suitable for translating between any
of the low voltage nodes (1.2 V, 1.5 V, 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.
