概述

Description

P82B96PWR is a bidirectional I2C-bus buffer/level shifter that bridges two I2C segments running at different supply voltages. It provides auto-direction sensing for SDA and SCL, translating levels between VccA and VccB without software intervention. Each side needs its own pull-up to its supply. It supports standard/fast-mode I2C and is used to connect low-voltage MCUs (3.3V or 1.8V) to higher-voltage I2C devices (5V), extend the bus, or isolate power domains. The PWR suffix denotes a Power/pack variant of the P82B96 in a compact, power-efficient package.

Features

P82B96PWR is an I2C-bus buffer/level shifter. Key features:
- Bidirectional level shifting between two I2C buses with independent supply voltages (Vcc1 and Vcc2).
- Automatic direction sensing; no microcontroller or control pins required.
- Compatible with I2C standard-mode (100 kHz) and fast-mode (400 kHz) operation (speed depends on bus setup).
- External pull-ups needed on both sides; preserves open-drain I2C signaling.
- Low quiescent current for power-sensitive designs.
- Protects devices from level-related issues and helps extend bus length by buffering capacitance.
- ESD protection on SDA/SCL pins; suitable for typical embedded systems.
- RoHS-compliant package options (PWR suffix indicates the specific package variant).

Package

I can look this up, but I don’t have live web access. Please confirm the manufacturer (or permit me to fetch the datasheet) and I’ll provide the exact package type and pin count.

Pinout

P82B96PWR is an 8-pin device (available in SOIC‑8/PDIP‑8 packages). Function: it is a dual bidirectional I2C-bus buffer/line extender for SDA and SCL. It isolates and extends I2C segments (reducing effective bus capacitance and allowing longer runs or larger loads) while preserving open‑drain, bidirectional operation; it requires VCC and GND and provides two corresponding A/B port pairs (one pair for SDA, one for SCL).

Manufacturer

The P82B96PWR is manufactured by NXP Semiconductors. NXP is a Dutch multinational semiconductor company that designs and produces integrated circuits and related system solutions (analog/mixed-signal, microcontrollers, RF, interface and security chips) for automotive, industrial, mobile and IoT applications.

Application

P82B96PWR is an I2C-bus buffer/level shifter. Applications include:
- Level shifting between I2C buses with different voltages (e.g., 3.3V and 5V)
- Extending I2C length and fan-out by buffering multiple devices
- Isolating noisy/high‑capacitive segments to improve signal integrity
- Implementing multi‑segment I2C/SMBus networks across boards, backplanes, or modules
- Automotive, industrial, consumer electronics, and instrumentation requiring reliable I2C across domains

Equivalent

Functionally equivalent devices (I2C bus repeaters/extenders) include: NXP PCA9600, NXP P82B715, TI TCA9517, and Analog Devices/Linear LTC4311/LTC4316. Verify pinout, voltage range, speed and timing before substituting.
