PCA9513AD,112

Signal Buffers, Repeaters, Splitters Overview

The PCA9513AD,112 is a hot-swappable I2C-bus and SMBus bus buffer manufactured by NXP Semiconductors. It operates within a supply voltage range of 2.7 V to 5.5 V and features a non-inverting single input to single output configuration. The device is housed in an 8-pin TSSOP or SOIC package suitable for surface mount installation. Key electrical specifications include a maximum propagation delay of 80 ns, a static current consumption of 16 uA, and a maximum operating supply current of 6 mA. It supports an extended industrial temperature range from -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix (e.g., 112 vs 118) against the required package type (SOIC vs TSSOP) before ordering. Confirm RoHS compliance status with the supplier. Check lead times as availability may vary. Ensure the component matches the design-in requirements for voltage and thermal performance.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when hot-swap protection and signal buffering are required for I2C or SMBus lines. Consider the package size constraints and operating temperature range. Verify compatibility with the system's voltage levels and bus speed requirements. Compare with similar accelerators if pinout or package differences are critical.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the PCA9513A series of bus buffers designed for I2C and SMBus interfaces. It is intended to isolate bus segments and improve signal quality. The device is commonly used in embedded systems requiring reliable communication between master and slave devices across different voltage domains.

Signal Buffers, Repeaters, Splitters Replacement Considerations

PCA9513D,112 is listed as no longer manufactured. PCA9513ADP,118 is a variant with a different package (TSSOP). Verify pinout and electrical equivalence before substitution.
