3-state
Rev. 4 — 6 August 2012
Product data sheet
1. General description
The NTB0101 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 1.2 V and 3.6 V and VCC(B) can be supplied at any
voltage between 1.65 V and 5.5 V, making the device suitable for translating between any
of the low voltage nodes (1.2 V, 1.5 V, 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): 1.2 V to 3.6 V and VCC(B): 1.65 V to 5.5 V
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 15000 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
