TCA9800DGKT

Translators, Level Shifters Overview

The TCA9800DGKT is a level-translating I2C bus buffer and repeater manufactured by Texas Instruments. It supports I2C and SMBus interfaces with a maximum clock frequency of 400 kHz. The device features two channels within an 8-pin VSSOP package. It operates with a supply voltage range of 800 mV to 3.6 V on one side and 1.65 V to 3.6 V on the other, enabling translation between low-voltage and standard logic levels. Propagation delays are specified at 40 ns and 100 ns. The component functions with open-drain inputs and outputs, drawing a typical operating current of 18 uA. It is rated for operation from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides bidirectional level translation between different voltage domains for I2C and SMBus signals.
• Functions as a bus buffer and repeater to extend signal reach and drive capability.
• Supports dual-channel configuration for simultaneous signal processing.

Translators, Level Shifters Applications

• Interfacing low-voltage microcontrollers with higher-voltage I2C peripherals.
• Extending I2C bus length in embedded systems.
• Signal buffering in mixed-voltage circuit designs.

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DGKT' corresponds to the VSSOP-8 package and tape-and-reel orientation required for your assembly process. Confirm that the voltage domain requirements match your system's A and B side supplies. Ensure compatibility with I2C/SMBus timing specifications before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level shifting between 0.8V-3.6V and 1.65V-3.6V domains is required. It is suitable for applications needing I2C bus extension or buffering. Consider the 8-pin VSSOP footprint for space-constrained designs. Verify that the 400 kHz speed meets system communication requirements.

Translators, Level Shifters Part Context

This part belongs to the TCA9800 series of level-shifting buffers. It is designed specifically for I2C and SMBus protocols. The DGKT suffix indicates the surface-mount VSSOP-8 packaging variant. It serves as a solution for connecting devices operating at different logic voltage levels within the same bus architecture.

Translators, Level Shifters Replacement Considerations

TCA9800DGKR is a parameter-equivalent alternative from Texas Instruments with the same functionality but potentially different reel packaging. Other similar level shifters may require verification of voltage ranges and channel counts.
