Product details

Overview

PI5C3384LE from Pericom Semiconductor is a 10-bit, 2-port bus switch IC with dual active-low bus enable inputs (BEA, BEB), 5Ω typical on-resistance, near-zero propagation delay (0.25 ns), and ultra-low quiescent current (0.2 μA typical), used to isolate or connect parallel data buses in notebook and portable computing systems.

For engineers reviewing the PI5C3384LE datasheet, PI5C3384LE pinout, PI5C3384LE application, or PI5C3384LE equivalent, key selection criteria include low on-resistance matching, dual independent 5-bit bus control, TSSOP-24 packaging, 5V operation, and high-impedance isolation during disable.

Technical Context

The PI5C3384LE implements two independent 5-bit bidirectional bus switches (A0–A4/B0–B4 and A5–A9/B5–B9), each controlled by separate active-low enable signals (BEA and BEB). It operates at 5V ±5% with no internal logic-switching is purely analog conduction through MOSFET-based pass gates.

Its architecture eliminates propagation delay beyond RC time constant (RON × CL), delivers <1.5 ns bus enable/disable timing, and maintains signal integrity via direct metal-to-metal connection when enabled and true Hi-Z isolation when disabled-no charge injection or level-shifting artifacts.

Key Specifications

Parameter	Value and Actual Design Meaning
On-Resistance (RON)	5 Ω typical - ensures minimal voltage drop and signal attenuation across switched paths at 48 mA.
Propagation Delay	0.25 ns typical - adds negligible timing skew between A/B ports, preserving high-speed bus timing budgets.
Quiescent Current (ICC)	0.2 μA typical - enables battery-sensitive applications like notebooks without measurable standby drain.
Input Capacitance (CIN)	6 pF - minimizes loading on driving sources and supports >100 MHz signal integrity in short traces.
Bus Enable Time (tPZH/tPZL)	1.5–6.5 ns - guarantees fast, deterministic bus arbitration for dynamic memory or peripheral switching.
Supply Voltage Range	4.75 V to 5.25 V - matches standard 5V TTL/CMOS logic rails with margin for ripple and droop.
Operating Temperature	–40°C to +85°C - qualified for industrial and mobile embedded environments without derating.

Pinout & Package

PI5C3384LE is housed in a Pb-free & Green 24-pin TSSOP (173-mil wide, 0.65 mm pitch) with exposed thermal pad not connected internally. Package dimensions: 7.7 mm × 4.3 mm × 1.2 mm (L × W × H).

Pin/Terminal	Circuit Role	Design Meaning
BEA, BEB	Active-Low Bus Enable Inputs	Independent controls for upper/lower 5-bit segments; LOW enables A↔B conduction, HIGH forces Hi-Z.
A0–A9	Port A Bidirectional Data Terminals	Connect directly to source-side bus; no internal buffering or direction control logic.
B0–B9	Port B Bidirectional Data Terminals	Connect directly to destination-side bus; symmetric conduction path with A pins.
VCC	Positive Supply Rail	Supplies gate bias for pass transistors; must be stable within ±5% of 5V for RON and timing specs.
GND	Signal and Power Reference	Common return for all I/O and internal switching; requires low-inductance local decoupling.

Key Features

Feature	Design Value
Direct analog bus connection	Eliminates logic-level translation, clock domain crossing, or setup/hold timing constraints.
Near-zero propagation delay	0.25 ns typical RC-limited delay preserves nanosecond-scale timing margins in high-speed parallel interfaces.
Dual independent 5-bit control	Enables selective gating of address/data sub-buses (e.g., A0–A4 for LSBs, A5–A9 for MSBs) without cross-talk.
Ultra-low quiescent power	0.2 μA ICC allows permanent installation in always-on subsystems without battery life impact.
Pb-free & Green TSSOP package	Meets RoHS 2011/65/EU and JEDEC J-STD-020 reflow profiles for lead-free manufacturing.

Applications

Notebook Memory Expansion Interface

PCI Express Slot Sharing Logic

Use Scenario: Isolating secondary SDRAM banks during CPU sleep states to reduce system leakage current.

IC Role / Device Role / Timing Role: Bidirectional analog switch enabling/disabling 10-bit address/data lines between memory controller and DRAM modules.

Use Value: 0.2 μA quiescent current prevents >10 μA standby drain per switch, critical for multi-bank memory retention.

Use Scenario: Sharing a single PCIe x1 slot between two peripherals (e.g., Wi-Fi + Bluetooth) via time-division multiplexing.

IC Role / Device Role / Timing Role: Low-latency bus switch routing PCIe configuration space and data lanes without protocol awareness.

Use Value: 0.25 ns propagation delay avoids violating PCIe Gen1 timing closure for 2.5 GT/s signaling.

Laptop Docking Station Multiplexer

Industrial PLC I/O Expansion Backplane

Use Scenario: Routing USB 2.0 D+/D− and SMBus lines between laptop and dock while maintaining signal integrity.

IC Role / Device Role / Timing Role: Passive analog switch isolating host-side and dock-side buses during hot-plug events.

Use Value: 5 Ω RON ensures <50 mV voltage drop at 100 mA, preserving USB differential swing and noise margin.

Use Scenario: Dynamically connecting sensor input channels to a shared ADC front-end in modular I/O racks.

IC Role / Device Role / Timing Role: High-impedance isolation switch preventing channel crosstalk and ground loop formation.

Use Value: Hi-Z state leakage <1 μA prevents false triggering of 12-bit SAR ADC reference thresholds.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 10-bit bus switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74CBT3384CPWR	Higher RON (7 Ω typ), wider SOIC-24 package, no Pb-free option in base part number.	Designed for industrial temperature range only; lacks green compliance documentation in legacy versions.	Prefer when existing PCB layout uses SOIC footprint and RoHS exemption applies.
PI5C3384QE	Identical electrical specs but in QSOP-24 (150-mil width); 0.1 mm taller, 0.4 mm narrower than TSSOP.	Same functional behavior; mechanical fit differs-requires board redesign for footprint compatibility.	Choose only if QSOP thermal performance or pick-and-place yield is prioritized over space-constrained layouts.

Compared with SN74CBT3384CPWR and PI5C3384QE, the PI5C3384LE offers the lowest on-resistance in the smallest footprint with guaranteed green compliance-making it optimal for space- and power-constrained portable designs where TSSOP-24 is already allocated.

The PI5C3384 series belongs to Pericom's low-voltage analog bus switch product line, engineered specifically for zero-delay, low-power interconnection of parallel digital buses in portable and embedded systems.

FAQ

What is the maximum capacitive load the PI5C3384LE can drive while maintaining specified propagation delay?

The datasheet specifies tPLH/tPHL under CL = 50 pF and RL = 500 Ω. At higher loads, delay increases linearly per τ = RON × CL; with 5 Ω RON, a 100 pF load adds ~0.5 ns delay. Signal integrity degrades above 100 pF due to increased rise-time degradation, so 50 pF is the design target for guaranteed timing.

Can BEA and BEB be tied together for single-enable operation?

Yes-BEA and BEB may be connected to a common control signal. This configures the device as a full 10-bit switch with unified enable. No electrical conflict occurs, as both inputs share identical logic thresholds (VIH = 2.0 V, VIL = 0.8 V) and drive strength.

Does the PI5C3384LE support hot-swap or live-insertion without damage?

No built-in hot-swap protection exists. The device lacks slew-rate control or current limiting on I/O pins. Applying voltage to A/B pins while VCC is unpowered risks latch-up or ESD damage. Always power VCC before asserting signals on any I/O terminal.

Is there a version of this switch that operates at 3.3V?

No-the PI5C3384LE is specified only for 4.75–5.25 V operation. For 3.3V systems, consider the PI3CH482 (8-bit, 3.3V, 8 Ω RON) or SN74CBTLV3861 (10-bit, 3.3V, 4 Ω RON), both pin-compatible alternatives with verified 3.3V timing and drive capability.
