Dual supply translating transceiver; open drain; auto
direction sensing
Rev. 2 — 11 February 2013
Product data sheet
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.
2. Features and benefits
Wide supply voltage range:
V
CC(A)
: 1.65 V to 5.5 V and V
CC(B)
: 1.65 V to 5.5 V
Maximum data rates:
50 Mbps
I
OFF
circuitry provides partial Power-down mode operation
Inputs accept voltages up to 5.5 V
ESD protection:
HBM JS-001 Class 2 exceeds 2000 V
CDM JESD22-C101E exceeds 2000 V
Latch-up performance exceeds 100 mA per JESD 78B Class II
