Diodes Incorporated PI5C16210BE

Overview

PI5C16210BE from Pericom Semiconductor is a 20-bit, dual-port bus switch IC with 5 Ω ON-resistance, active-low bus enable control (1OE/2OE), and flow-through pinout for low-noise signal routing in high-speed digital systems. It operates from 4 V to 5.5 V, supports –40°C to +85°C industrial temperature range, and delivers near-zero propagation delay (0.25 ns typical) with ultra-low quiescent power (0.5 μW).

For engineers reviewing the PI5C16210BE datasheet, PI5C16210BE pinout, PI5C16210BE application, or PI5C16210BE equivalent, this device is selected for high-fidelity bidirectional data path switching in notebook memory expansion, FPGA I/O bridging, and PCI Express Gen1/Gen2 sideband signal routing where ground bounce and timing skew must be minimized.

Technical Context

The PI5C16210BE implements two independent 10-bit bidirectional analog bus switches per port, each controlled by dedicated active-low enable inputs (1OE, 2OE). Switch conduction is governed solely by MOSFET channel resistance without internal logic or level-shifting circuitry.

Its architecture provides true flow-through pin mapping (e.g., 1A1 ↔ 1B1, 2A1 ↔ 2B1), eliminating signal layer crossover on PCBs. The 5 Ω R_ON ensures minimal voltage drop (<150 mV at 30 mA) and RC-limited delay (~0.25 ns with 50 pF load), preserving edge integrity for signals up to 200 MHz.

Key Specifications

Pinout & Package

FAQ

Is PI5C16210BE compatible with 3.3 V logic levels?

No. PI5C16210BE requires V_CC between 4.0 V and 5.5 V for guaranteed operation. Its VIH minimum is 2.0 V, but input thresholds and R_ON performance are specified only across the 4–5.5 V supply range. Driving control or data pins with 3.3 V signals may result in undefined switching behavior or increased R_ON.

Can PI5C16210BE be used for analog signal switching?

Yes-within limits. Its 5 Ω R_ON and 3.4 pF COFF support low-distortion switching of DC to ~200 MHz analog signals (e.g., clock distribution, audio I²S, or low-speed differential pairs), provided signal swing remains within V_CC–GND and no DC bias exceeds absolute maximum ratings (–0.5 V to +7.0 V).

What is the thermal performance of the BQSOP package?

The 48-pin BQSOP (B48) package has a junction-to-ambient thermal resistance (θ_JA) of 90°C/W (typical, still air). With 0.5 μW quiescent power and ≤100 mA per pin max, junction temperature rise remains negligible (<0.01°C) under normal operation-no heatsink or airflow required.

Does PI5C16210BE include ESD protection on I/O pins?

Yes. All A/B pins feature integrated clamp diodes with V_IK = –0.7 V (typ) at –18 mA, providing ±2 kV HBM ESD robustness per JEDEC JS-001. This eliminates need for external TVS devices in most notebook and docking station environments.
