NTB0101A
Auto direction sensing dual supply
Rev. 1 â 14 July 2015
Product data sheet
1. General description
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 (VCC(A) and VCC(B)). VCC(A) can be
supplied at any voltage between 1.2 V and 3.6 V. VCC(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 VCC(A) and pin B is referenced to VCC(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 IOFF. The IOFF circuitry disables the
output, preventing damage of the device due to backflow current, when it is powered
down.
