1. General description
The NTSX2102 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)
). Both
supplies can be supplied at any voltage between 1.65 V and 5.5 V. This flexibility makes
the device suitable for translating between any of the voltage nodes (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.
