NTSX2102 Dual supply translating transceiver; open drain; auto direction sensing Rev. 2 — 11 February 2013 Product data sheet 1. General description The NTSX2102 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)). Both supplies can be supplied at any voltage between 1.65 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 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 5.5 V and VCC(B): 1.65 V to 5.5 V  Maximum data rates:  50 Mbps  IOFF circuitry provides partial Power-down mode operation  Inputs accept voltages up to 5.5 V  ESD protection:  HBM JS-001 Class 2 exceeds 2000 V  CDM JESD22-C101E exceeds 2000 V  Latch-up performance exceeds 100 mA per JESD 78B Class II  Multiple package options  Specified from 40 C to +85 C 3.
