NTS0103
Dual supply translating transceiver; open drain; auto
direction sensing
Rev. 2 — 10 November 2011
Product data sheet
1. General description
The NTS0103 is a 3-bit, dual supply translating transceiver with auto direction sensing,
that enables bidirectional voltage level translation. It features two 3-bit input-output ports
(An and Bn), 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 1.65 V and 3.6 V and V
CC(B)
can be supplied at
any voltage between 2.3 V and 5.5 V, making 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 3.6 V and V
CC(B)
: 2.3 V to 5.5 V
Maximum data rates:
Push-pull: 50 Mbps
I
OFF
circuitry provides partial Power-down mode operation
Inputs accept voltages up to 5.5 V
ESD protection:
HBM JESD22-A114E Class 2 exceeds 2500 V for A port
HBM JESD22-A114E Class 3B exceeds 8000 V for B port
MM JESD22-A115-A exceeds 200 V
CDM JESD22-C101E exceeds 1500 V
IEC61000-4-2 contact discharge exceeds 8000 V for B port
Latch-up performance exceeds 100 mA per JESD 78B Class II
