PI3DBS12412AZHE

PI3DBS12412AZHE is a part number from the PI3 family (Pericom, now Diodes Inc.) for a high-speed, multi-channel bidirectional signal switch or crosspoint/bus switch. It is designed to route data signals on PCBs, enabling functions such as multiplexing, data-bus sharing, or channel selection without relays. The device typically operates from a single supply, features low on-resistance when ON, high off-isolation, and fast switching to support high-speed digital or video signals. It may include ESD protection and accepts standard CMOS/TTL-level inputs, and it comes in a compact surface-mount package (suffix AZHE). Applications include backplane routing, memory or processor interconnects, FPGA/I/O interfacing, and test equipment requiring flexible, programmable signal routing. For precise specs (Rds(on), bandwidth, number of channels, Vcc, pinout), consult the exact datasheet. I can summarize if you share it or help locate it.

PI3DBS12412AZHE is a Pericom (Renesas) PI3DBS family bus switch / crosspoint device. Key features typically include:
- 12 bidirectional data paths with 3-state outputs (independent enable/control)
- Low on-resistance pass gates for fast data transfer
- Single-supply operation with CMOS/TTL-compatible I/O
- ESD protection on all I/O pins; latch-up immune
- Pb-free, RoHS-compliant package (AZHE)
- Compact packaging suitable for high-density routing
- Suitable for data routing, bus multiplexing/demultiplexing in memory, video, and communications paths
Note: exact electrical specs (RDS(on), supply range, propagation delay, I/O voltage range) vary by version; please refer to the specific datasheet for precise numbers.

Pin count: 24 pins.
Function: PI3DBS12412AZHE is a 12-to-4 (12 inputs, 4 outputs) analog bus switch (12×4 crosspoint switch) used to route signals between inputs and outputs under digital control.

- Manufacturer: Pericom Semiconductor (now part of Renesas Electronics).
- What kind of company: A global semiconductor company that designs and sells integrated circuits, focusing on interconnect, timing, and signal‑integrity ICs.

PI3DBS12412AZHE is a high‑speed bus switch/crosspoint device. Typical application areas include:
- Routing and buffering of multi‑bit data paths in backplanes, motherboards, and embedded systems
- Multi‑lane video/data interfaces and high‑speed interconnects (LVDS‑like, similar buses)
- Memory‑interface signal routing and isolation to reduce crosstalk
- Networking/telecom equipment for data path multiplexing and signal integrity
- General signal integrity tasks (level shifting, impedance matching, bus fanout) in complex PCBs

I can’t determine the package type from the part number alone. Please provide the manufacturer or a datasheet link. The packaging (e.g., SSOP, TSSOP, QFN) is specified in the datasheet’s Mechanical/Packaging section.
