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 (V_CC(A)and V_CC(B)). V_CC(A)can be supplied at

any voltage between 1.2 V and 3.6 V and V_CC(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 V_CC(A)and pins Bn are referenced to V_CC(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 I_OFF. The I_OFFcircuitry disables the output, preventing the

damaging backflow current through the device when it is powered down.

2. Features and benefits

•

Wide supply voltage range:

V_CC(A): 1.2 V to 3.6 V and V_CC(B): 1.65 V to 5.5 V

•

I_OFFcircuitry 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

11. Application information

11.1. Applications

systems operating at different supply voltages. See Fig. 7 for a typical operating circuit using the

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 V_CCO= 1.2 V to 1.8 V, 50 Ω at

V_CCO= 1.8 V to 3.3 V and 40 Ω at V_CCO= 3.3 V to 5.0 V.

11.3. Input driver requirements

For correct operation, the device driving the data I/Os of the NXB0108 must have a minimum drive

capability of ±2 mA See Fig. 9 for a plot of typical input current versus input voltage.

11.4. Power up

During operation V_CC(A)must never be higher than V_CC(B), however during power-up V_CC(A)

≥

V_CC(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 V_CC(A)or V_CC(B)is switched off.

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 (t_diswith no external load) indicates

the delay between when OE goes LOW and when outputs actually become disabled. The enable

time (t_en) 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

open drain driver applications such as 1-Wire or I²C. For these applications, the NXS0108 level

translator is recommended.

Definitions

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.

internal review and subject to formal approval, which may result in

modifications or additions. Nexperia does not give any representations or

warranties as to the accuracy or completeness of information included herein

and shall have no liability for the consequences of use of such information.

Short data sheet — A short data sheet is an extract from a full data sheet
