SN74AVC1T45DCKT

Translators, Level Shifters Overview

The SN74AVC1T45DCKT is a single-bit dual-supply bus transceiver from Texas Instruments, designed for configurable voltage level translation. It operates with VCCA and VCCB supply voltages ranging from 1.08V to 3.6V, enabling bidirectional data transfer between logic nodes at 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device features non-inverting logic with three-state outputs and a propagation delay of 5.6ns. It supports an operating temperature range of -40°C to +85°C and utilizes a 6-pin SC-70 package.

Translators, Level Shifters Feature Summary

• Configurable dual power rails allow independent voltage selection for Port A and Port B to facilitate low-voltage bidirectional translation.
• Integrated Ioff circuit disables outputs during partial power-down conditions to prevent excessive current flow.
• Direction control input activates either the B-port or A-port output to manage data flow direction between buses.

Translators, Level Shifters Applications

• Asynchronous communication between two data buses
• Voltage level translation between 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V nodes
• Partial power-down applications requiring isolation

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DCKT' corresponds to the SC-70 tape-and-reel packaging configuration. Confirm that the required supply voltage range aligns with the 1.08V to 3.6V specification for both VCCA and VCCB. Ensure the application environment remains within the -40°C to +85°C operating temperature limits defined for this component variant.

Translators, Level Shifters Selection Notes

Select this component when a single-channel bidirectional translator is needed for mixed-voltage systems. It is suitable for designs requiring configurable voltage levels between 1.2V and 3.6V. Consider the SC-70 package size for space-constrained layouts. Verify that the 5.6ns propagation delay meets the timing requirements of the target asynchronous communication interface.

Translators, Level Shifters Part Context

This part belongs to the SN74AVC1T45 family of single-bit dual-supply bus transceivers. It shares functional characteristics with variants such as SN74AVC1T45DCKR and SN74AVC1T45YZPR, differing primarily in packaging and reel specifications. The family is optimized for general-purpose low-voltage translation in portable and industrial electronics.

Translators, Level Shifters FAQ

How does the device handle partial power-down scenarios?

The SN74AVC1T45DCKT includes an Ioff circuit that automatically disables the outputs when power is removed, preventing damage caused by back-driving currents.

What is the supported voltage range for the supply rails?

Both VCCA and VCCB can operate independently within a range of 1.08V to 3.6V, allowing flexibility in connecting different voltage domains.
