The EVM may be reconfigured for use with two ISO1540 or two ISO1541 instead of one of each. This Guide presents a typical laboratory setup used with this EVM. CAUTION This Evaluation Module (EVM) is made available for isolator parameter performance evaluation only and is not intended for isolation voltage testing. To prevent damage to the EVM, any voltage applied as a supply or digital input/output must be maintained within the 0 V to 5.5 V recommended operating range. Exceeding the specified input voltage range may cause unexpected operation and irreversible damage to the EVM. If there are questions concerning the input voltage range, contact a TI field representative prior to connecting power. Applying loads outside the specified output range may result in unintended operation and possible permanent damage to the EVM. If there is uncertainty as to the load specification, contact a TI field representative. 1.1 Overview The ISO154x devices are low-power, bidirectional isolators that are compatible with I2C interfaces. The logic input and output buffers on these devices are separated by TI’s Isolation technology utilizing a silicon dioxide (SiO2) barrier. When used in conjunction with isolated power supplies, these devices block high voltages, isolate grounds and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry. The ISO1540 has two isolated bidirectional channels for clock and data lines and is fit for multi-master applications. The ISO1541 has a bidirectional data and a unidirectional clock channel and is useful in applications that have a single master. These devices achieve isolated bidirectional communication by introducing an offset, making the side 1 low-level output greater than the side 1 low-level input and thus preventing an internal logic latch that otherwise would occur with standard digital isolators. 1.2 ISO154xEVM Kit Contents 1.

Typical input and output waveforms are included. 2.1 Overview The basic setup in Figure 2-1 has the two power supplies required to evaluate isolator performance with any combination of 3.3 V or 5 V on either side. If both sides are evaluated at the same supply voltage, only one power supply is required and can be used to power both sides of the EVM. CAUTION Note that this EVM is for operating parameter performance evaluation only and not designed for isolation voltage testing. Any voltage applied above the 5.5-V maximum recommended operating voltage of the isolators may damage the EVM. Please note that if the ISO1541 is used, providing an input signal on the SCL2 pin does not yield any output on SCL1, SCL1 remains pulled up to VCC1.

Typical Waveforms, Inputs on Side 1 Figure 2-3 illustrates SDA2 and SCL2 of U1 being treated as inputs and driven by an I2C transmitter connected to J3B/J4B (for SDA2) and J5B/J6B (for SCL2). The output waveforms for SDA1 and SCL1 are captured on the oscilloscope at J3A/J4A and J5A/J6A respectively. Note the low level of the SDA1 and SCL1 outputs offset from the ground level. This is due to the high output low level on side 1 designed to prevent a latch-up state.
