NXS0108-Q100  
Dual supply translating transceiver; open drain;  
auto direction sensing  
Rev. 1 — 15 September 2020  
Product data sheet  
1. General description  
The NXS0108-Q100 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 voltage nodes (1.2 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.  
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100  
(Grade 1) and is suitable for use in automotive applications.

11. Application information  
11.1. Voltage level-translation applications  
The NXS0108-Q100 can be used in point-to-point applications to interface between devices or  
systems operating at different supply voltages. The device is primarily targeted at I2C or 1-wire  
which use open-drain drivers, it may also be used in applications where push-pull drivers are  
connected to the ports, however the NXB0108-Q100 may be more suitable.

Fig. 9. Architecture of NXS0108-Q100 I/O cell (one channel)  
The NXS0108-Q100 is a "switch" type voltage translator, it employs two key circuits to enable  
voltage translation:  
1. A pass-gate transistor (N-channel) that ties the ports together.  
2. An output edge-rate accelerator that detects and accelerates rising edges on the I/O pins.  
The gate bias voltage of the pass gate transistor (T3) is set at approximately one threshold voltage  
above the VCC level of the low-voltage side. During a LOW-to-HIGH transition the output one-shot  
accelerates the output transition by switching on the PMOS transistors (T1, T2) bypassing the  
10 kΩ pull-up resistors and increasing current drive capability. The one-shot is activated once the  
input transition reaches approximately VCCI/2; it is de-activated approximately 50 ns after the output

NXS0108-Q100  
Dual supply translating transceiver; open drain; auto direction sensing  
reaches VCCO/2. During the acceleration time the driver output resistance is between approximately  
50 Ω and 70 Ω. To avoid signal contention and minimize dynamic ICC, the user should wait for the  
one-shot circuit to turn-off before applying a signal in the opposite direction. Pull-up resistors are  
included in the device for DC current sourcing capability.  
11.3. Input driver requirements  
As the NXS0108-Q100 is a switch type translator, properties of the input driver directly effect the  
output signal. The external open-drain or push-pull driver applied to an I/O determines the static  
current sinking capability of the system; the max data rate, HIGH-to-LOW output transition time  
(tTHL) and propagation delay (tPHL) are dependent upon the output impedance and edge-rate of  
the external driver. The limits provided for these parameters in the datasheet assume a driver with  
output impedance below 50 Ω is used.  
11.4. Output load considerations  
The maximum lumped capacitive load that can be driven is dependant upon the one-shot pulse  
duration. In cases with very heavy capacitive loading there is a risk that the output will not reach  
the positive rail within the one-shot pulse duration.To avoid excessive capacitive loading and to  
ensure correct triggering of the one-shot it's recommended to use short trace lengths and low  
capacitance connectors on NXS0108-Q100 PCB layouts. To ensure low impedance termination  
and avoid output signal oscillations and one-shot re-triggering, the length of the PCB trace  
should be such that the round trip delay of any reflection is within the one-shot pulse duration  
(approximately 50 ns).  
11.5. 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 NXS0108-Q100 includes circuitry that disables all  
output ports when either VCC(A) or VCC(B) is switched off.  
11.6. 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.  
11.7. Pull-up or pull-down resistors on I/O lines  
The NXS0108-Q100 has the pull-up resistors dynamically change value based on whether a low or  
a high is being passed through the I/O line. Each A-port I/O has a pull-up resistor (RPUA) to VCCA  
and each B-port I/O has a pull-up resistor (RPUB) to VCCB. RPUA and RPUB have a value of 40 kΩ  
when the output is driving LOW. RPUA and RPUB have a value of 4 kΩ when the output is driving  
HIGH. RPUA and RPUB are disabled when OE = LOW. This feature provides lower static power  
consumption (when the I/Os are passing a LOW) and supports lower VOL values for the same size  
pass-gate transistor and helps improve simultaneous switching performance.
