PCA9513ADP,118

Signal Buffers, Repeaters, Splitters Overview

The PCA9513ADP,118 is a hot swappable I2C-bus and SMBus buffer manufactured by NXP Semiconductors in an 8-lead TSSOP package. It operates within a supply voltage range of 2.7 V to 5.5 V and supports clock frequencies from 0 Hz to 400 kHz. The device features bidirectional buffering for SDA and SCL lines, preventing bus corruption during live board insertion. Key electrical parameters include a maximum operating temperature of +85 °C, a minimum of -40 °C, and a typical supply current of 6 mA at 5.5 V. It incorporates built-in rise time accelerators with a 0.8 V threshold and provides a 92 μA current source on the SCLIN and SDAIN pins.

Signal Buffers, Repeaters, Splitters Feature Summary

• Bidirectional buffering isolates backplane and card capacitances to prevent signal corruption during hot swapping
• Built-in delta-V/delta-t rise time accelerators improve noise margin with a 0.8 V threshold
• Integrated 92 μA current sources on input pins maintain consistent RC time constants for multidrop applications
• Digital ENABLE input controls low-current mode while open-drain READY output indicates connection status

Signal Buffers, Repeaters, Splitters Applications

• cPCI, VME, and AdvancedTCA cards requiring safe insertion into multipoint backplanes
• PICMG backplane systems utilizing integrated pull-up current sources
• Systems supporting multiple master arbitration and clock stretching

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific ordering suffix ,118 corresponds to the TSSOP8 (MSOP8) package variant as defined in the official NXP documentation. Confirm that the component meets RoHS compliance requirements for your target assembly process. Ensure the procurement channel provides valid traceability for this NXP Semiconductors part number.

Signal Buffers, Repeaters, Splitters Selection Notes

Select the PCA9513ADP,118 when designing systems requiring hot-swappable I/O cards for cPCI or VME architectures. This model is distinct from the PCA9514A due to its integrated 92 μA current sources on the SCLIN and SDAIN pins, making it suitable for PICMG backplane applications where consistent pull-up behavior is critical during card insertion and removal cycles.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to the PCA9513A/PCA9514A family of hot swappable bus buffers. The PCA9513ADP,118 specifically denotes the TSSOP8 package version. It shares functional similarities with the PCA9511A but offers improved noise margins through a higher rise time accelerator threshold. The dynamic offset design allows series or parallel connection with other devices in the same family.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PCA9514ADP,118 serves as a functional substitute lacking the integrated input current sources. The PCA9513AD,118 is available in an SO8 package instead of TSSOP8. Verify pin compatibility and feature differences before substituting.
