PCA9600DP/S911,118

Signal Buffers, Repeaters, Splitters Overview

The PCA9600DP/S911,118 is a dual bidirectional bus buffer designed to isolate I2C-bus capacitance for point-to-point or multipoint applications up to 4000 pF. It operates at speeds of at least 1 MHz with Fast-mode Plus (Fm+) compatibility on the high drive side. The device features temperature-stabilized logic voltage levels at its SX/SY interface, allowing interfacing with non-I2C buses like SMBus or PMBus. Supply voltage ranges from 2.5 V to 15 V, while TX/TY outputs provide 60 mA sink capability. It splits signals into unidirectional paths for galvanic isolation and offers ESD protection exceeding 3500 V HBM.

Signal Buffers, Repeaters, Splitters Feature Summary

• Isolates I2C-bus capacitance to support long-distance communication
• Splits bidirectional signals into unidirectional TX/RX pairs for isolation
• Temperature-stabilized logic levels compatible with various bus standards

Signal Buffers, Repeaters, Splitters Applications

• Interface between I2C-buses operating at different logic levels
• Long-distance point-to-point or multipoint architectures
• Galvanic isolation using opto-couplers or magnetic coupling

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix S911,118 against official NXP documentation to confirm package orientation and marking details. Ensure compliance with RoHS directives as indicated in the product data sheet. Confirm that the TSSOP8 package variant matches the required PCB footprint and thermal management specifications for the target application environment.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when isolating high capacitance loads exceeding standard I2C limits. It serves as a higher-speed alternative to the P82B96, supporting Fm+ specifications. Consider its ability to interface with TTL-based systems and its low power supply current characteristics. Verify that the 15 V maximum rating aligns with the system's voltage requirements.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PCA9600 series of dual bidirectional bus buffers manufactured by NXP Semiconductors. It is functionally similar to the PCA9601 but lacks the specific 15 mA SX/SY sink capability found in the PCA9601 variant. The series is designed to bridge normal I2C buses with higher capacitance or different voltage configurations.

Signal Buffers, Repeaters, Splitters Replacement Considerations

PCA9600DPZ is a drop-in alternate for PCA9600DP variants. The P82B96 is a predecessor model with lower speed capabilities. Ensure pinout compatibility when substituting, as both use SO8 and TSSOP8 packages.
