Test data is given in Table 13.

All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz; ZO = 50 Ω; dV/dt ≥ 1.0 V/

ns.

RL = Load resistance.

CL = Load capacitance including jig and probe capacitance.

VEXT = External voltage for measuring switching times.

[1]

VCCI is the supply voltage associated with the input.

[2]

For measuring data rate, pulse width, propagation delay, and output rise and fall measurements, RL = 1 MΩ; for measuring enable and disable times, RL =

50 KΩ.

[3]

VCCO is the supply voltage associated with the output.

13 Application information

13.1 Applications

Voltage level-translation applications. The NTS0102 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 NTB0102 may be more suitable.
