Product details
Overview
PI3B32160AE from Pericom Semiconductor is a 16-bit to 32-bit bidirectional demultiplexing bus switch with precharged outputs, designed for high-speed PCI hot-plug and system-level signal routing. It features 5 Ω typical on-resistance, 14 pF maximum channel-on capacitance, 250 ps propagation delay, and operates from 3.0 V to 3.6 V over –40°C to +85°C.
For engineers reviewing the PI3B32160AE datasheet, PI3B32160AE pinout, PI3B32160AE application, or PI3B32160AE equivalent, key selection criteria include low-capacitance switching performance, dual-bank SEL/VBIAS control, rail-to-rail logic compatibility, and TSSOP-56 packaging for dense PCB layouts in hot-swap-capable systems.
Technical Context
The PI3B32160AE implements two independent 16-bit demux banks (A→B1/B2), each controlled by dedicated SEL and VBIAS pins, enabling simultaneous or selective routing of 16 input signals to either of two 16-bit output buses. Its CMOS transmission-gate architecture ensures bidirectional signal flow with near-zero DC offset and no internal level-shifting circuitry.
Each bank supports independent bias voltage (VBIAS1/VBIAS2) for optimized turn-on threshold and precharge control, reducing dynamic switching noise. The device requires VCC applied before any signal or bias voltage to prevent latch-up, and all logic inputs tolerate up to 3.6 V regardless of VCC level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 3.0 V to 3.6 V - Ensures compatibility with 3.3 V LVTTL and LVCMOS systems without external regulation. |
| RON (typ.) | 5 Ω - Enables minimal signal attenuation and preserves edge integrity for >100 MHz data paths. |
| CON (max.) | 14 pF - Limits capacitive loading on source drivers, supporting fast rise/fall times in high-speed buses. |
| tPLH/tPHL (typ.) | 0.25 ns - Delivers sub-nanosecond propagation, critical for timing-critical PCI/PCI-X hot-plug handshaking. |
| ICC (typ.) | 50 μW - Supports ultra-low static power in always-on system management interfaces. |
| Operating Temp | –40°C to +85°C - Validated for industrial-grade embedded and telecom infrastructure applications. |
| Input Capacitance | 2.6 pF (typ.) - Reduces driver load and minimizes reflections on stubbed or daisy-chained traces. |
Pinout & Package
Package: 56-pin TSSOP (Pb-free & Green, JEDEC MO-153 compliant), 0.5 mm pitch, 14.0 × 6.1 mm body size, 1.2 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A–16A | Input/Output Bank A | 16 bidirectional data lines routed to B1 or B2 banks under SEL control. |
| 1B1–16B1 | Output Bank B1 | First 16-bit demux output bank; driven only when SEL1 = HIGH and VBIAS1 active. |
| 1B2–16B2 | Output Bank B2 | Second 16-bit demux output bank; driven only when SEL2 = HIGH and VBIAS2 active. |
| SEL1 / SEL2 | Bank Enable Control | Active-HIGH per-bank select; enables routing from A to corresponding B bank. |
| VBIAS1 / VBIAS2 | Bias Reference Input | Defines turn-on threshold for respective B1/B2 banks; accepts 1.3 V to VCC. |
| VCC / GND | Power Supply | Single 3.3 V supply with dedicated power/ground pairs for noise isolation. |
Key Features
| Feature | Design Value |
|---|---|
| Precharged Outputs | Reduces switching noise and ground bounce during hot-plug insertion by holding B1/B2 lines at VBIAS until enabled. |
| Rail-to-Rail Logic Inputs | Accepts 0 V to 3.6 V control signals independent of VCC, simplifying interface with mixed-voltage controllers. |
| Dual Independent Banks | Enables concurrent or staggered routing of two 16-bit data streams without inter-bank crosstalk. |
| Low I/O Capacitance | 2.6 pF input / 4.7 pF B-side off-capacitance minimizes signal distortion in high-frequency backplane traces. |
Applications
| PCI Hot-Plug Controller Interface | Server Backplane Signal Multiplexing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit demultiplexing bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PI3B32442AE | 32-bit to 64-bit demux; higher RON (7 Ω typ.), larger 64-pin TQFP package | Targets wider bus widths; lacks precharged outputs and dual VBIAS control | Select when scaling to 32-bit source buses and board space permits larger footprint |
| SN74CBT3244PW | 16-bit to 32-bit demux; 6 Ω RON, 15 pF CON, no VBIAS pins or precharge, 56-pin TSSOP | Requires external pull-ups; less robust against hot-plug transients due to uncontrolled output state | Select for cost-sensitive non-hot-plug applications where precharge is not required |
Compared with PI3B32442AE and SN74CBT3244PW, the PI3B32160AE uniquely delivers precharged outputs and dual independent VBIAS control-critical for glitch-free hot-plug operation-while maintaining the lowest on-resistance and smallest package among functionally aligned demux switches.

FAQ
What is the maximum allowable voltage on SEL and VBIAS pins relative to VCC?
SEL and VBIAS pins accept 0 V to 3.6 V regardless of VCC level, enabling direct interfacing with 3.3 V or 5 V control logic without level shifters. Absolute maximum rating is +4.6 V, but operation above VCC + 0.3 V may increase leakage current beyond specification limits.
Can both B1 and B2 banks be enabled simultaneously for the same A input?
No. Enabling both SEL1 and SEL2 simultaneously causes contention on shared A pins, as the device does not support wired-OR or bus-keeper functionality. Each A pin connects exclusively to either B1 or B2; concurrent activation violates the intended demux topology and risks excessive current draw.
Is PI3B32160AE compatible with 2.5 V logic systems?
No. The device requires VCC between 3.0 V and 3.6 V for guaranteed operation. At 2.5 V, RON increases significantly (>12 Ω), propagation delay degrades beyond spec, and VBIAS thresholds become unstable-making it unsuitable for 2.5 V systems without level translation.
Does the device require external pull-up resistors on B1/B2 outputs?
No. Internal weak pull-ups are integrated on all B1 and B2 pins, eliminating external components. These pull-ups activate only when the corresponding bank is disabled (SEL = LOW), holding outputs at VBIAS to prevent floating states during hot-plug transitions.
