ST2378EBJR

Translators, Level Shifters Overview

The ST2378EBJR is an 8-bit, dual-supply, bidirectional level translator from STMicroelectronics. It interfaces low-voltage ASICs/PLDs with higher voltage systems using externally applied voltages VL and VCC within the range of 1.71 V to 5.5 V. The device supports a guaranteed data rate of 13 Mbps over the entire operating voltage range. Key electrical parameters include a maximum propagation delay (tPD) of 15 ns at TA = 85 °C, VL = 1.8 V, and VCC = 5.5 V. It features ±15 kV ESD protection on I/Os at the VCC side. Power consumption in disable mode is less than 1 μA.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'E' indicates the TSSOP package variant as documented in official datasheets. Confirm that the ordering code matches the required pin count and package type. Ensure the component meets the specified operating temperature range and voltage requirements for your application design.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level shifting between 1.71 V and 5.5 V domains is required. It is suitable for applications needing high-speed data rates up to 13 Mbps. Consider the ESD protection levels and low standby current if power efficiency is critical. Verify compatibility with I2C bus requirements due to its open-drain and totem pole output capabilities.

Translators, Level Shifters Part Context

The ST2378E series consists of 8-bit bidirectional level translators designed for mixed-voltage system integration. These devices utilize transmission-gate-based designs to facilitate independent data flow direction per channel. The family is characterized by wide operating voltage ranges and robust ESD performance, making them standard components for bridging logic families with different supply voltages.

Translators, Level Shifters Replacement Considerations

Check for other STMicroelectronics level shifters with similar 8-bit configurations and voltage ranges. Verify pinout compatibility and package dimensions before substituting. Ensure the alternative part supports the required 13 Mbps data rate and ESD protection specifications.
