Product details

Overview

PI5C32160CAE from Pericom Semiconductor is a 16-to-32-bit bidirectional demultiplexing bus switch designed for PCI Hot-Plug applications. It features 5Ω typical on-resistance, 250ps propagation delay, –1.5V undershoot protection on the A-port only, 15pF max channel on-capacitance, and operates from +4.5V to +5.5V over –40°C to +85°C.

For engineers reviewing the PI5C32160CAE datasheet, PI5C32160CAE pinout, PI5C32160CAE application, or PI5C32160CAE equivalent, key selection criteria include hot-plug robustness, sub-nanosecond signal integrity, rail-to-rail logic compatibility, and TSSOP-56 packaging for high-density PCI expansion slots.

Technical Context

The PI5C32160CAE implements a dual-path demux architecture controlled by SEL1/SEL2 inputs, enabling routing of 16-bit A-bus data to either 16-bit B1-bus, 16-bit B2-bus, or both simultaneously. Its CMOS transmission-gate design supports bidirectional signal flow with no internal latching or level-shifting.

Undershoot protection is implemented exclusively on the A-port input pins (–1.5V rating), while B1/B2 ports feature integrated pull-ups. VBIAS1/VBIAS2 pins set gate bias for optimal R_ON stability across voltage and temperature, and all control inputs tolerate up to +5.5V regardless of V_CC.

Key Specifications

Parameter	Value and Actual Design Meaning
On-Resistance (R_ON)	5 Ω typical - ensures minimal voltage drop and signal distortion at 48 mA switching current
Propagation Delay	0.25 ns typical - enables sub-nanosecond timing alignment in high-speed PCI bus segments
Channel On-Capacitance	13.5 pF typical - maintains >100 MHz bandwidth into 20 pF load for PCI clock/data integrity
Supply Voltage Range	+4.5 V to +5.5 V - matches standard 5 V PCI signaling rails with ±10% tolerance
Operating Temperature	–40°C to +85°C - supports industrial-grade hot-plug insertion in server backplanes
ESD Rating	2000 V HBM - protects against handling-induced discharge during live slot insertion
Undershoot Protection	–1.5 V on A-port only - prevents latch-up during transient negative excursions on upstream bus lines

Pinout & Package

Package: 56-pin TSSOP (240-mil wide, Pb-free & Green compliant), 0.5 mm pitch, 13.9 × 8.1 mm body size, 1.20 mm max height.

Pin/Terminal	Circuit Role	Design Meaning
A0–A15	Input/Output Data Bus (16-bit)	Primary bidirectional data path; supports undershoot protection and rail-to-rail logic drive
B1_0–B1_15	Demux Output Bus 1 (16-bit)	First 16-bit output path; includes internal pull-up resistors for default high state
B2_0–B2_15	Demux Output Bus 2 (16-bit)	Second 16-bit output path; also includes internal pull-up resistors
SEL1, SEL2	Demux Control Inputs	Two-bit select code determining routing: L/H → B1 only, H/L → B2 only, L/L → B1+B2, H/H → high-Z
VBIAS1, VBIAS2	Bias Voltage Inputs	Set gate bias for transmission gates; must be ≥1.3 V and ≤V_CC for stable R_ON
V_CC	Power Supply	+4.5 V to +5.5 V supply; powers internal logic and switch bias circuitry

Key Features

Feature	Design Value
Bidirectional signal routing	Enables shared bus arbitration between multiple downstream devices without direction control logic
Rail-to-rail logic compatibility	Control inputs accept 0 V to +5.5 V regardless of V_CC, simplifying interface with mixed-voltage systems
Integrated B-port pull-ups	Eliminates external resistors on B1/B2 buses, reducing BOM count and board space in hot-plug connectors
Low quiescent current	70 µA typical ICC enables low-power standby states in PCIe/PCI carrier cards
Hot-plug optimized I/O structure	Asymmetric undershoot protection (A-port only) aligns with PCI mechanical insertion sequence and signal coupling behavior

Applications

PCI Express Carrier Card

Server Backplane Slot

Use Scenario: Hot-plug insertion of add-in cards into powered server chassis with active PCI bus traffic.

IC Role / Device Role / Timing Role: Demultiplexes host-side 16-bit PCI data to dual 16-bit downstream lanes during plug detection and enumeration phases.

Use Value: Enables zero-delay signal pass-through and undershoot containment on upstream traces, preventing system reset during mechanical mating.

Use Scenario: Dynamic reconfiguration of multi-slot backplanes supporting redundant I/O modules.

IC Role / Device Role / Timing Role: Isolates and routes PCI address/data cycles between primary and secondary bus segments during module swap.

Use Value: Maintains <100 ps added jitter and <5 Ω path resistance, preserving PCI timing margins under live insertion stress.

Industrial Control I/O Module

Embedded Test Equipment

Use Scenario: Field-replaceable I/O expansion in programmable logic controllers with continuous operation requirements.

IC Role / Device Role / Timing Role: Acts as configurable bus splitter between CPU bus and modular analog/digital I/O banks.

Use Value: Supports –40°C to +85°C operation and 2000 V HBM ESD, ensuring reliability in electrically noisy factory environments.

Use Scenario: Reconfigurable signal routing in automated test fixtures for PCI-based instrumentation cards.

IC Role / Device Role / Timing Role: Provides selectable 1:1 or 1:2 fanout for clock and data lines during test mode switching.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bus demultiplexing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
PI5C3257AE	8-to-16-bit demux, lower channel count, identical R_ON and timing specs	Suitable for half-width PCI slots or legacy CompactPCI designs with reduced lane count	Select when full 16→32 fanout is unnecessary and board space is constrained
SN74CBT3245APW	8-bit FET bus switch, no built-in undershoot protection or VBIAS pins	Lacks hot-plug-specific protection; requires external clamping and biasing for PCI use	Choose only for non-hot-plug, cost-sensitive 5 V logic isolation where protection is handled externally

Compared with PI5C3257AE and SN74CBT3245APW, the PI5C32160CAE uniquely delivers full 16→32 demux capability with integrated –1.5V A-port undershoot protection and VBIAS-controlled R_ON stability-critical for reliable PCI Hot-Plug compliance without external components.

FAQ

What is the function of VBIAS1 and VBIAS2 pins?

VBIAS1 and VBIAS2 set the gate bias voltage for the internal transmission gates to maintain stable on-resistance across temperature and supply variations. They must be driven between 1.3 V and V_CC; tying them directly to V_CC is acceptable and commonly used in PCI applications where maximum R_ON stability is required.

Can SEL1 and SEL2 be left floating?

No. SEL1 and SEL2 are CMOS inputs with no internal termination; floating states may cause undefined routing behavior or increased ICC. They must be actively driven to valid logic levels (L or H) or tied via pull-up/down resistors to ensure deterministic demux operation during power-up and hot-plug events.

Does the PI5C32160CAE support 3.3 V PCI-X signaling?

No. The device requires V_CC = +4.5 V to +5.5 V and is specified only for 5 V PCI signaling. Its logic thresholds and undershoot protection are calibrated for 5 V operation; using it with 3.3 V PCI-X violates absolute maximum ratings and invalidates timing and protection guarantees.

Is there a recommended PCB layout practice for minimizing crosstalk?

Yes. Route A0–A15 differentially with matched lengths and ground guard traces between B1/B2 buses. Place V_CC and VBIAS decoupling capacitors (0.1 µF X7R) within 3 mm of respective pins, and avoid routing high-speed signals beneath the TSSOP thermal pad, which is electrically connected to ground in this package variant.
