Diodes Incorporated PI5C16210VE

Overview

PI5C16210VE 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 simplified PCB layout. It operates from 4 V to 5.5 V, supports –40°C to +85°C industrial temperature range, and delivers near-zero propagation delay in high-speed data path isolation applications such as notebook memory expansion buses.

For engineers reviewing the PI5C16210VE datasheet, PI5C16210VE pinout, PI5C16210VE application, or PI5C16210VE equivalent, key selection criteria include low-impedance bidirectional switching, ultra-low quiescent power (0.5 μW typical), absence of ground bounce, and compatibility with 3.3 V/5 V logic systems requiring clean signal pass-through without timing skew.

Technical Context

The PI5C16210VE 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 CMOS transmission gate architecture - no internal latching, level-shifting, or buffering is present.

All 20 A/B channel pairs exhibit matched ON-resistance (5 Ω typ. at V_CC = 4.5 V, I_ON = 30 mA) and sub-1 ns propagation delay contribution, with input/output capacitance limited to 2.4 pF (C_IN) and 3.4 pF (C_OFF) to minimize loading on driving and receiving circuits.

FAQ

Is PI5C16210VE compatible with 3.3 V logic levels?

Yes. PI5C16210VE accepts 3.3 V logic inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and operates from 4.0 V to 5.5 V supply, making it fully interoperable with 3.3 V I/O systems while maintaining 5 V tolerance on all pins. Its 5 Ω ON-resistance ensures minimal voltage drop even at 3.3 V signaling.

Does PI5C16210VE require external pull-up or pull-down resistors on OE pins?

No. The 1OE and 2OE inputs have TTL-compatible thresholds and internal weak pull-downs are not required. Driving OE directly from FPGA or microcontroller GPIO (with VOL ≤ 0.8 V for logic LOW) is sufficient. External resistors add unnecessary loading and are omitted in reference designs.

Can PI5C16210VE be used in hot-swap applications?

Yes. Its near-zero propagation delay, absence of ground bounce, and bidirectional operation make it suitable for hot-swap bus isolation. The device remains in high-impedance state (Z) when OE is HIGH, preventing back-driving during insertion. Maximum ratings include –0.5 V to +7.0 V on all I/O pins, supporting safe transient handling.

What is the maximum capacitive load PI5C16210VE can drive reliably?

PI5C16210VE is characterized up to 50 pF load capacitance, with propagation delay contribution remaining below 0.25 ns. For loads exceeding 50 pF, rise/fall time degradation follows standard RC behavior (τ ≈ R_ON × C_L). At 5 Ω and 100 pF, τ = 0.5 ns - still acceptable for ≤100 MHz bus operation with proper termination.
