Product details

Overview

PI3VT3306UEX from Pericom Semiconductor is a 2-bit, 2-port bus switch IC performing bidirectional voltage translation between 3.3V and 2.5V or 2.5V and 1.8V domains, featuring 5Ω typical on-resistance, near-zero propagation delay (0.25ns), and active-low bus enable control. It operates from a single 2.5V or 3.3V supply and supports level-shifting in memory interface and mixed-voltage I/O interconnects.

For engineers reviewing the PI3VT3306UEX datasheet, PI3VT3306UEX pinout, PI3VT3306UEX application, or PI3VT3306UEX equivalent, key selection criteria include verified bidirectional level translation capability, sub-1ns enable/disable timing, on-resistance stability across voltage rails, and Pb-free MSOP-8 packaging compliance for space-constrained PCB layouts.

Technical Context

This device implements a passive FET-based bus switch architecture with no internal logic or latching-signal path integrity is preserved via low-R_ON MOSFETs controlled directly by BEn inputs. Translation occurs inherently through supply-rail referenced conduction: when V_CC = 3.3V and A/B pins driven to 3.3V, output swings to ~2.5V; at V_CC = 2.5V, outputs translate to ~1.8V.

Switching behavior is governed solely by gate drive from BEn and rail voltage, with no internal bias networks or direction control. Propagation delay is dominated by R_ON-C_LOAD time constant (≤0.25ns for 50pF), making it suitable for high-speed parallel buses where deterministic latency and minimal signal distortion are required.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	2.5V or 3.3V ±10% - defines supported I/O domain pairs: 3.3V↔2.5V or 2.5V↔1.8V
On-Resistance (R_ON)	5Ω typ. at V_CC = 3.3V, I_ON = –8mA - ensures <50mV voltage drop at 10mA load, preserving signal swing
Propagation Delay	0.25ns max (A↔B) - negligible added latency in DDR, PCI, or parallel data paths
Enable/Disable Time	1.5ns to 6.5ns (3.3V), 1.5ns to 9.8ns (2.5V) - supports fast bus arbitration and power-gating sequences
Input Capacitance	3.5pF typ. - minimizes loading on driving source, critical for high-frequency clock/data lines
Off-State Capacitance	5.0pF typ. - limits crosstalk and feedthrough when switch is disabled
Quiescent Current	3µA max - enables use in always-on voltage translation without significant standby power penalty

Pinout & Package

PI3VT3306UEX is packaged in an 8-pin, 118-mil wide Pb-free and RoHS-compliant MSOP (U) package with exposed pad not electrically connected.

Pin/Terminal	Circuit Role	Design Meaning
GND	Ground reference	Return path for all internal switches and enable logic; must be low-inductance connection
VCC	Power supply input	Defines output voltage translation level (2.5V or 3.3V); powers internal gate drive circuitry
BE1, BE2	Active-low bus enable inputs	Independent control per port; pull-up required for power-up high-impedance default state
A1, A2	Port A bidirectional terminals	Connect to higher-voltage domain (e.g., 3.3V CPU I/O); no direction pin required
B1, B2	Port B bidirectional terminals	Connect to lower-voltage domain (e.g., 2.5V memory); automatically follows A-side voltage via R_ON

Key Features

Feature	Design Value
Bidirectional level translation	Supports 3.3V↔2.5V and 2.5V↔1.8V without external components or direction control
Sub-nanosecond propagation delay	0.25ns max ensures timing-critical parallel buses (e.g., address/data multiplexing) remain unaffected
Low on-resistance (5Ω)	Maintains signal integrity under 10–12mA loads common in FPGA-to-ASIC or SoC-to-peripheral interfaces
Independent dual-port enable	BE1/BE2 allow selective activation of A1↔B1 and A2↔B2 paths for dynamic bus partitioning
Pb-free MSOP-8 footprint	118-mil width enables high-density routing in compact embedded systems while meeting environmental compliance

Applications

IC Role / Device Role / Timing Role: Dual-port switch providing independent enable control per peripheral channel for dynamic power management.

Use Value: Enables simultaneous operation of 1.8V and 3.3V devices on same MCU bus with <1ns added delay.

PCI Bus Segmentation

Equivalent & Alternatives

The following parts are listed as comparable options for similar bidirectional voltage translation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AVC4T245RTER	Direction-controlled, dual-supply (V_CCA/V_CCB), 12Ω R_ON, 3.5ns propagation delay	Requires explicit DIR pin and two independent supplies; better for asymmetric voltage pairs (e.g., 1.8V↔5V)	Select when direction awareness or wider voltage range is needed; avoid if minimal latency and simplicity are priorities.
TXS0102DCUR	Auto-direction sensing, dual-supply, 10Ω R_ON, 3.2ns propagation delay, integrated auto-bias	Self-biasing eliminates external resistors but adds 2.5ns latency; limited to ≤3.3V domains	Prefer for hot-swap or dynamic bus reversal; not suitable for sub-1ns timing-critical paths.

Compared with SN74AVC4T245RTER and TXS0102DCUR, PI3VT3306UEX delivers the lowest propagation delay (0.25ns vs. ≥3.2ns) and simplest control (no DIR pin or bias network), making it optimal for fixed-direction, ultra-low-latency parallel bus translation where supply rails align to 2.5V/3.3V/1.8V standards.

FAQ

What is the maximum capacitive load the PI3VT3306UEX can drive while maintaining specified propagation delay?

The datasheet specifies 0.25ns propagation delay with C_L = 50pF and R_L = 500Ω. At higher loads, delay increases linearly per the R_ON-C_L time constant (5Ω × C_L). For example, at 100pF, expected delay remains below 0.5ns-still suitable for most DDR1/2 and parallel flash interfaces.

Can PI3VT3306UEX translate between 3.3V and 1.8V directly?

No. The device performs only adjacent-rail translation: 3.3V supply yields 2.5V output; 2.5V supply yields 1.8V output. Direct 3.3V-to-1.8V translation requires cascading two devices or selecting a dedicated wide-range translator like TXB0108.

Is a pull-up resistor required on BE1/BE2, and what value is recommended?

Yes-a pull-up resistor is mandatory for power-up safety to ensure high-impedance (disconnected) default state. A 10kΩ resistor to V_CC is recommended, as confirmed in the truth table note and application guidance; values from 4.7kΩ to 100kΩ are acceptable depending on noise immunity needs.

Does PI3VT3306UEX support hot-swap or live insertion into a powered system?

It supports partial hot-swap: the absolute maximum ratings include –0.5V to +5.5V DC input voltage and –0.5V to +4.6V supply voltage, allowing safe biasing during insertion. However, no built-in current-limiting or slew-rate control means external series resistors are advised for robust live-insertion in high-capacitance backplanes.
