Diodes Incorporated PI3B16233AE

Overview

PI3B16233AE from Pericom Semiconductor is a 3.3V, 16-bit to 32-bit FET mux/demux NanoSwitch™ with 5 Ω ON resistance, 4.5 ns max propagation delay, and ultra-low quiescent current (0.2 mA typical), used for memory bank interleaving in high-speed embedded systems.

For engineers reviewing the PI3B16233AE datasheet, PI3B16233AE pinout, PI3B16233AE application, or PI3B16233AE equivalent, key selection criteria include bidirectional switching capability, rail-to-rail logic compatibility up to +3.6 V, industrial temperature range (–40°C to +85°C), and Pb-free TSSOP-56 packaging.

Technical Context

The PI3B16233AE implements dual 8-bit-to-16-bit or single 16-bit-to-32-bit multiplexing via two independent select inputs (SEL1, SEL2) and two test inputs (TEST1, TEST2). It operates as a passive FET-based analog switch - not a logic gate - enabling bidirectional signal flow without level translation.

All A, B1, and B2 ports support rail-to-rail input voltage (–0.5 V to +4.6 V), independent of V_CC. Switching is controlled solely by digital logic levels on SEL/TEST pins; no internal clock or bias circuitry is required.

Supply support for PI3B16233AE includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Pericom Semiconductor was a fabless provider of high-speed interface and signal integrity solutions, acquired by Diodes Incorporated in 2016; its legacy timing, switching, and signal conditioning products remain in active production and support.

The PI3B16233 belongs to Pericom's NanoSwitch™ family - designed specifically for low-latency, low-power analog switching in memory, bus, and interconnect applications where traditional logic-based muxes introduce unacceptable delay or power overhead.

FAQ

Can PI3B16233AE operate with 2.5 V or 1.8 V logic inputs?

Yes - its logic inputs accept –0.5 V to +4.6 V regardless of V_CC, so 1.8 V or 2.5 V control signals directly drive SEL/TEST pins without level shifting. Signal integrity on A/B ports remains unaffected since switching is FET-based and voltage-independent.

Does PI3B16233AE require external pull-up or pull-down resistors on control pins?

No - SEL1, SEL2, TEST1, and TEST2 have CMOS-compatible input structure with no internal termination. External resistors are optional and only needed if system-level noise immunity or default-state assurance is required; typical designs rely on driver-sourced logic levels.

What is the maximum continuous current per switch channel?

The absolute maximum DC output current is 120 mA per channel, verified per device characterization and consistent with 5 Ω R_ON and 0.5 W total power dissipation limit. Derating is not required below 85°C ambient when using recommended PCB copper area.

Is PI3B16233AE pin-compatible with PI3B16233A?

Yes - PI3B16233AE shares identical pinout, electrical behavior, and mechanical dimensions with PI3B16233A; the "E" suffix denotes Pb-free & Green compliance only, with no functional or layout differences.
