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 (VCC(A) and VCC(B)). VCC(A) can be supplied with any voltage between 1.2 V and
3.6 V and VCC(B) can be supplied with any voltage between 1.65 V and 5.5 V. This flexibility makes 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 VCC(A) and pins Bn are referenced to VCC(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 IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through
the device when it is powered down.
