74LVC2T45FK,LF(CB

Translators, Level Shifters Overview

The SN74LVC2T45 is a dual bus transceiver designed for asynchronous communication between two independent buses operating at different voltage levels. It supports configurable power supply rails ranging from 1.65V to 5.5V, allowing Port A to track VCCA and Port B to track VCCB. This architecture enables low-voltage bidirectional translation across various logic nodes including 1.8V, 2.5V, 3.3V, and 5V. The device features VCCA-based direction control inputs and offers high ESD protection performance exceeding JESD22 specifications.

Translators, Level Shifters Feature Summary

• Configurable dual-rail design supporting independent power supplies for each port
• VCC isolation ensures high-impedance state if either supply is grounded
• Supports partial power-down mode via Ioff circuitry to prevent backflow current
• Direction control input logic activates specific port outputs for data routing

Translators, Level Shifters Applications

• Personal electronics
• Industrial systems
• Enterprise infrastructure
• Telecommunications equipment

Translators, Level Shifters Procurement Notes

Verify the manufacturer designation carefully as the model prefix indicates Toshiba Semiconductor and Storage, while the core logic family originates from Texas Instruments. Confirm package type compatibility with your PCB footprint requirements. Ensure voltage levels on both ports fall within the specified 1.65V to 5.5V range during operation. Check for specific suffix variations that may denote tape and reel packaging or lead-free status.

Translators, Level Shifters Selection Notes

Select this component when interfacing buses with differing voltage domains requiring bidirectional data transfer. Consider the maximum data rate capabilities relative to the target voltage conversion scenario. Evaluate the need for VCC isolation features to protect against ground faults. Verify that the required ESD protection levels meet your system's environmental standards before finalizing the design.

Translators, Level Shifters Part Context

This device belongs to the LVC (Low Voltage CMOS) logic family, optimized for low-power applications in portable electronics. It serves as a bridge between legacy 5V systems and modern low-voltage microcontrollers. The dual-transceiver configuration allows simultaneous handling of multiple data lines, making it suitable for parallel bus architectures in compact form factors.

Translators, Level Shifters Replacement Considerations

Direct substitutes include the SN74LVCH2T45 which offers similar functionality with enhanced characteristics. Other compatible options from different manufacturers may require verification of pinout compatibility and electrical parameter alignment.
