ST16C32245TBR

Translators, Level Shifters Overview

The ST16C32245TBR is a 14-bit dual supply bus transceiver and level translator manufactured by STMicroelectronics. It facilitates asynchronous two-way communication between buses operating at different voltage levels, specifically interfacing a 3 V A-port with a 2.5 V or 1.8 V B-port. The device operates within a VCCA range of 2.3 V to 3.6 V and a VCCB range of 1.65 V to 2.7 V. It features balanced propagation delays, power-down protection on inputs and outputs, and integrated bus hold functionality. The component includes 26 Ω series resistors on the A-side outputs and dedicated I2C lines for fast data rate translation.

Translators, Level Shifters Feature Summary

• Supports high-speed bidirectional data transmission with symmetrical output impedance and balanced propagation delays.
• Includes integrated 26 Ω series resistors on A-side outputs to reduce line noise in high-speed applications.
• Provides power-down protection on all inputs and outputs to prevent current leakage during system power-off states.
• Features embedded bus hold circuits on data inputs to eliminate the need for external pull-up or pull-down resistors.

Translators, Level Shifters Applications

• Interface between 3.3 V buses and 2.5 V or 1.8 V buses in mixed-voltage systems
• Fast I2C line level translation for 1.8 V and 2.8 V environments
• Two-way asynchronous communication between data buses

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix 'TBR' corresponds to the μTFBGA42 package type and tape and reel packaging configuration as specified in the official datasheet. Confirm that the procurement documentation matches the specific revision history and environmental compliance standards required for the target application design.

Translators, Level Shifters Selection Notes

Select this component when designing mixed-voltage systems requiring interface between 3 V and lower voltage domains such as 2.5 V or 1.8 V. Ensure the application requires 14-bit parallel data paths and benefits from integrated series resistance for signal integrity. Verify that the operating temperature range of -40 °C to +85 °C meets the environmental constraints of the deployment scenario.
