PCA9513DP,118

Signal Buffers, Repeaters, Splitters Overview

The PCA9513DP,118 is a hot swappable I2C and SMBus bus buffer manufactured by NXP Semiconductors. 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 bi-directional buffering for SDA and SCL lines with a propagation delay (tPLH) of 20 ns and (tPHL) of 380 ns under standard test conditions. It includes a digital ENABLE input and an open-drain READY output. The component is housed in an 8-pin plastic TSSOP package.

Signal Buffers, Repeaters, Splitters Selection Notes

Select the PCA9513DP,118 when designing multi-point backplane systems that require hot swapping functionality. This component is suitable for applications needing isolation between backplane and card capacitances while maintaining I2C and SMBus compatibility up to 400 kHz.

Signal Buffers, Repeaters, Splitters Part Context

This component belongs to the PCA9513/PCA9514 series of hot swappable bus buffers. It shares functional similarities with the PCA9510, PCA9511, and PCA9512 but offers improved noise margins through its specific rise time accelerator threshold. It is distinct from the PCA9514 which lacks the integrated current source feature.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The PCA9514DP serves as a functional substitute if the integrated 92 μA current source is not required. Other members of the PCA951x family may be considered, though pinout and feature differences must be evaluated carefully.
