PI3DBS12412AZHE

PI3DBS12412AZHE is a PI3-series bus switch device. It is a multi-channel, bidirectional signal-switching IC used to route data lines on a PCB, allowing you to connect or isolate signals between devices or power domains as needed. The “AZHE” suffix denotes the specific package type, temperature rating, and revision for this part.
Key points:
- Purpose: control data path routing, bus multiplexing, or level shifting with enable control.
- Typical features (per datasheet): channel count, low on-resistance, controlled on/off state, input/output protection, and ESD protection; operates within a defined voltage range.
- Applications: data buses in microcontrollers/MCUs, memory interfaces, display/video interfaces, or any design needing configurable signal routing and isolation.
What to do next:
- Look up the official datasheet from the manufacturer or a major distributor to confirm exact specs: number of channels, Vcc range, control logic polarity, Ron, propagation delay, package, and operating temperature.
- Check availability and pricing on supplier pages.

PI3DBS12412AZHE is in a 24-pin QFN package (4x4 mm).

- Pin count: 20 pins (TO- or SOP-style, e.g., TSSOP-20/SOIC-20).
- Function: PI3DBS12412AZHE is a dual bidirectional bus switch (PI3DBS family). It provides two independent bidirectional data paths with tri-state outputs, controlled by enable signals, enabling routing or isolation of two digital buses on a common line with low on-resistance.

Manufacturer: Pericom Semiconductor Corporation (now part of Renesas Electronics). Company type: a fabless semiconductor company that designs high-speed data interconnect, timing, and switch ICs (signal-integrity/interface devices).

PI3DBS12412AZHE is a high-speed, low-skew bus switch/crosspoint for routing differential data signals. Typical applications:
- PCIe/USB/HDMI-DisplayPort signal routing
- DDR/LPDDR memory bus routing
- Serial data paths in consumer electronics
- Automotive infotainment and sensors
- Test/measurement equipment and data acquisition systems
