NXB0108 Dual supply translating transceiver; auto direction sensing; 3-state Rev. 2 — 3 November 2021 Product data sheet 1. General description The NXB0108 is an 8-bit, dual supply translating transceiver with auto direction sensing, that enables bidirectional voltage level translation. It features two 8-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 1.2 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 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): 1.2 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: ANSI/ESDA/Jedec JS-001 Class 2 exceeds 2500 V for A port • HBM: ANSI/ESDA/Jedec JS-001 Class 3B exceeds 15000 V for B port • CDM: ANSI/ESDA/Jedec JS-002 Class C3 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 3.

Applications Voltage level-translation applications. The NXB0108 can be used to interface between devices or systems operating at different supply voltages. See Fig. 7 for a typical operating circuit using the NXB0108. 1.8 V 3.3 V 0.1 µF VCC(A) 1.8 V 0.1 µF VCC(B) 3.3 V OE SYSTEM CONTROLLER A1 B1 A2 B2 A3 B3 A4 DATA A5 NXB0108 SYSTEM B4 B5 A6 B6 A7 B7 A8 B8 DATA GND aaa-032228 Fig. 7. Typical operating circuit 11.2. Architecture The architecture of the NXB0108 is shown in Fig. 8. The device does not require an extra input signal to control the direction of data flow from A to B or from B to A. In a static state, the output drivers of the NXB0108 can maintain a defined output level, but the output architecture is designed to be weak, so that they can be overdriven by an external driver when data on the bus starts flowing in the opposite direction. The output one shots detect rising or falling edges on the A or B ports. During a rising edge, the one shots turn on the PMOS transistors (T1, T3) for a short duration, accelerating the low-to-high transition. Similarly, during a falling edge, the one shots turn on the NMOS transistors (T2, T4) for a short duration, accelerating the high-to-low transition. During output transitions the typical output impedance is 70 Ω at VCCO = 1.2 V to 1.8 V, 50 Ω at VCCO = 1.8 V to 3.3 V and 40 Ω at VCCO = 3.3 V to 5.0 V.

Typical input current versus input voltage graph 11.4. Power up During operation VCC(A) must never be higher than VCC(B), however during power-up VCC(A) ≥ VCC(B) does not damage the device, so either power supply can be ramped up first. There is no special power-up sequencing required. The NXB0108 includes circuitry that disables all output ports when either VCC(A) or VCC(B) is switched off.

All rights reserved 15 / 21 NXB0108 Nexperia Dual supply translating transceiver; auto direction sensing; 3-state 11.5. Enable and disable An output enable input (OE) is used to disable the device. Setting OE = LOW causes all I/Os to assume the high-impedance OFF-state. The disable time (tdis with no external load) indicates the delay between when OE goes LOW and when outputs actually become disabled. The enable time (ten) indicates the amount of time the user must allow for one one-shot circuitry to become operational after OE is taken HIGH. To ensure the high-impedance OFF-state during power-up or power-down, pin OE should be tied to GND through a pull-down resistor, the minimum value of the resistor is determined by the current-sourcing capability of the driver. 11.6. Pull-up or pull-down resistors on I/O lines As mentioned previously the NXB0108 is designed with low static drive strength to drive capacitive loads of up to 70 pF. To avoid output contention issues, any pull-up or pull-down resistors used must be kept higher than 50 kΩ. For this reason the NXB0108 is not recommended for use in 2 open drain driver applications such as 1-Wire or I C. For these applications, the NXS0108 level translator is recommended.
