NTB0101AGW: Auto direction sensing dual supply

Overview

The NTB0101A is a 1-bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation. It consists of two 1-bit I/O 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 1.2 V and 3.6 V. V_CC(B) can be supplied at any voltage between 1.65 V and 5.5 V. This flexibility allows translation 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 V_CC(A) and pin B is referenced to V_CC(B). A HIGH 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 damage of the device due to backflow current, when it is powered down.
