PCA9306DCUR Description

Short technical summary and product information.

The PCA9306DCUR from Texas Instruments is a 2-bit bidirectional voltage level translator designed for I2C and SMBus communication. It facilitates voltage translation between systems operating at different voltage levels, supporting VCCA from 1.2V to 3.3V and VCCB from 1.8V to 5.5V. This device operates at frequencies up to 400 kHz.

 

Key features include auto-direction sensing, eliminating the need for a direction pin. It offers low ON-state resistance of 3.5 Ω for minimal signal distortion and 5-V tolerant I/O ports for mixed-mode signal operation. The translator provides bidirectional translation with open-drain I/O ports and features a high-impedance state when the enable pin is low, ensuring lockup-free operation.

 

Packaged in an 8-VSSOP, the PCA9306DCUR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. The device also includes ESD protection exceeding 2000V (HBM) and 1000V (CDM), with latch-up performance exceeding 100 mA.
