SN74AVC1T45DBVT

Translators, Level Shifters Overview

The SN74AVC1T45DBVT is a single-bit, non-inverting configurable voltage level translator manufactured by Texas Instruments. It operates with two independent power rails, VCCA and VCCB, supporting voltage ranges from 1.2V to 3.6V. The device facilitates bidirectional data translation between different logic voltage nodes, including 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. Key electrical specifications include a propagation delay of 5.6 ns and a maximum data rate of 500 Mbps. It features three-state outputs and is housed in an SOT-23-6 package.

Translators, Level Shifters Feature Summary

• Configurable dual-supply operation allowing flexible voltage translation between low-voltage nodes
• Supports partial power-down applications through integrated Ioff circuitry that disables outputs during power loss
• Direction control input manages data flow direction between A and B ports for asynchronous communication

Translators, Level Shifters Applications

• Asynchronous communication between two data buses operating at different voltage levels
• Low-voltage bidirectional translation in portable and battery-powered devices
• System interfaces requiring isolation during partial power-down states

Translators, Level Shifters Procurement Notes

Verify the specific suffix DBVT corresponds to the SOT-23-6 tape and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process standards. Ensure the ordering part number matches the exact manufacturer designation to avoid variant discrepancies regarding temperature range or output drive characteristics.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring translation between mixed voltage domains such as 1.2V to 3.3V. The SOT-23-6 package is suitable for space-constrained surface-mount designs. Consider the 5.6 ns propagation delay for timing-critical paths. Verify that the DIR pin is powered by VCCA as specified in the functional description to ensure correct direction control logic.

Translators, Level Shifters Part Context

This device belongs to the SN74AVC1T45 family of single-bit bus transceivers. It is designed specifically for low-voltage applications where multiple supply voltages coexist on a single board. The family emphasizes flexibility through configurable power rails and robust protection features like over-voltage tolerant inputs and high-impedance states during power-off conditions.
