These devices have logic input and output • Supports up to 1-MHz Operation buffers that are separated by Texas Instruments • 3-V to 5.5-V Supply Range Capacitive Isolation technology using a silicon dioxide (SiO ) barrier. When used with isolated power 2 • Open-Drain Outputs With 3.5-mA Side 1 and 35- supplies, these devices block high voltages, isolate mA Side 2 Sink Current Capability grounds, and prevent noise currents from entering the • –40°C to +125°C Operating Temperature local ground and interfering with or damaging • ±50-kV/µs Transient Immunity (Typical) sensitive circuitry. • HBM ESD Protection of 4 kV on All Pins; This isolation technology provides for function, 8 kV on Bus Pins performance, size, and power consumption • Safety-Related Certifications: advantages when compared to optocouplers. The ISO1540 and ISO1541 devices enable a complete – 4242-V Isolation per DIN V VDE V 0884-10 PK 2 isolated I C interface to be implemented within a (VDE V 0884-10): 2006-12 small form factor. – 2500-V Isolation for 1 Minute per UL 1577 RMS The ISO1540 has two isolated bidirectional channels – CSA Component Acceptance Notice 5A, IEC for clock and data lines while the ISO1541 has a 60950-1 and IEC 61010-1 End Equipment bidirectional data and a unidirectional clock channel. Standards The ISO1541 is useful in applications that have a – CQC Basic Insulation per GB4943.1-2011 single master while the ISO1540 is suitable for multi- master applications. For applications where clock stretching by the slave is possible, the ISO1540 2 Applications device should be used. 2 • Isolated I C Buses Isolated bidirectional communication is accomplished • SMBus and PMBus Interfaces within these devices by offsetting the low-level output • Open-Drain Networks voltage on side 1 to a value greater than the high- • Motor Control Systems level input voltage on side 1, thus preventing an internal logic latch that otherwise would occur with • Battery Management standard digital isolators. 2 • I C Level Shifting (1) Device Information PART NUMBER PACKAGE BODY SIZE (NOM) ISO1540 SOIC (8) 4.90 mm × 3.91 mm ISO1541 (1) For all available packages, see the orderable addendum at the end of the data sheet.
