NTB0101A Auto direction sensing dual supply Rev. 1 14 July 2015 Product data sheet 1. General description The NTB0101A is a 1-bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation. It consists of two 1-bit I/O ports (A and B), one output enable input (OE) and two supply pins (V and V ). V can be CC(A) CC(B) CC(A) supplied at any voltage between 1.2 V and 3.6 V. V can be supplied at any voltage CC(B) between 1.65 V and 5.5 V. This flexibility allows translation 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 V and pin B is referenced to V . A HIGH level at CC(A) CC(B) pin OE causes the outputs to assume a high-impedance OFF-state. This device is fully specified for partial power-down applications using I . The I circuitry disables the OFF OFF output, preventing damage of the device due to backflow current, when it is powered down. 2. Features and benefits Wide supply voltage range: V : 1.2 V to 3.6 V and V : 1.65 V to 5.5 V CC(A) CC(B) I circuitry provides partial power-down mode operation OFF Inputs accept voltages up to 5.5 V ESD protection: HBM JESD22-A114E Class 2 exceeds 2500 V for port A HBM JESD22-A114E Class 3B exceeds 15000 V for port B MM JESD22-A115-A exceeds 200 V CDM JESD22-C101E exceeds 1500 V Latch-up performance exceeds 100 mA per JESD 78B Class II Specified from 40 Cto+85 C and 40 Cto+125 CNTB0101A NXP Semiconductors Auto direction sensing dual supply 3.
