Detailed Description

Ultra-small dual bidirectional voltage level translator for open-drain buses such as I2C/SMBus. One device, two channels, automatic direction sensing, open-drain I/O. Wide supply ranges on each side for easy mixed-voltage interfacing. Tiny 8-UDFN 1.45 x 1.0 mm package for dense layouts. Surface-mount, RoHS3 compliant, -55°C to +125°C operating temperature. Base product number PCA9306.

Key Features

2 bidirectional channels with auto-direction sensing

Open-drain I/O, optimized for I2C and SMBus lines

VCCA 1.0 to 3.6 V on the low-voltage side

VCCB 1.8 to 5.5 V on the high-voltage side

Single translator circuit per IC

8-UDFN package, 1.45 x 1.0 mm footprint

Surface-mount mounting type

Operating temperature range -55°C to +125°C (TA)

RoHS3 compliant

Typical use requires external pull-up resistors on both sides of the bus

EN pin allows clean enable/disable of translation

Key Advantages

Simple, reliable level shifting between 1.0–3.3 V controllers and 1.8–5.5 V peripherals

Auto-direction removes firmware handling of bus direction

Open-drain behavior maintains I2C/SMBus signal integrity

Very small package saves board space in wearables, sensors, and compact modules

Wide temperature range suits industrial and harsh environments

Low power, passive FET architecture minimizes heat and simplifies power design

Packaging

Shipment type Tape & Reel (TR) for automated assembly

Package and case 8-UDFN (1.45 x 1.0 mm); also noted as 8-UFDFN in some sources

Supplier device package 8-UDFN (1.45 x 1.0 mm)

Mounting type Surface Mount
