NTS0101
Dual supply translating transceiver; open drain; auto
direction sensing
Rev. 5 — 11 August 2014
Product data sheet
1. General description
The NTS0101 is a 1-bit, dual supply translating transceiver with auto direction sensing,
that enables bidirectional voltage level translation. It features two 1-bit input-output 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 1.65 V and 3.6 V. VCC(B) can be supplied at any
voltage between 2.3 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 A and OE are
referenced to VCC(A) and pin B is 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
