NTS0102
Dual supply translating transceiver; open drain; auto
direction sensing
Rev. 3 — 17 November 2011
Product data sheet
1. General description
The NTS0102 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 (VCC(A) and VCC(B)). VCC(A)
can be supplied at any voltage between 1.65 V and 3.6 V and VCC(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
VCC(A) and pins Bn are referenced to VCC(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 IOFF. The IOFF 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:
VCC(A): 1.65 V to 3.6 V and VCC(B): 2.3 V to 5.5 V
Maximum data rates:
Push-pull: 50 Mbps
IOFF 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
Latch-up performance exceeds 100 mA per JESD 78B Class II
Multiple package options
Specified from 40 C to +85 C and 40 C to +125 C
