General description

The NTB0101 is a 1-bit, dual supply translating transceiver with auto direction sensing,

that enables bidirectional voltage level translation. It features two 1-bit input-output ports

(A and B), one output enable input (OE) and two supply pins (VCC(A) and VCC(B)). VCC(A)

can be supplied at any voltage between 1.2 V and 3.6 V and VCC(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 A and OE are referenced to VCC(A) and pin B is 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.
