74LVT2245PW,118

Overview

The Nexperia 74LVT2245PW,118 is an octal bus transceiver featuring integrated 30 Ω output termination resistors and 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V. The device provides bidirectional data transfer with TTL input and output switching levels. It includes overvoltage tolerant inputs up to 5.5 V and bus hold functionality to eliminate external pull-up requirements for unused inputs.

Feature Summary

• Integrated 30 Ω output termination resistors for signal integrity
• Bus hold data inputs to define unused inputs without external components
• Overvoltage tolerant inputs allowing direct interface with 5.5 V systems
• IOFF circuitry enabling partial power-down mode operation

Applications

• Octal bidirectional bus interfaces
• Systems requiring live insertion and extraction
• Direct interfacing between 3.3 V logic and 5 V buses

Procurement Notes

Verify the specific package variant against the ordering information table. Confirm that the application environment remains within the recommended operating temperature range of -40 °C to +85 °C. Ensure supply voltage does not exceed the absolute maximum rating of 4.6 V to prevent permanent damage. Check for compliance with relevant JEDEC standards if required by the design specification.

Selection Notes

Select this component when internal termination is required to reduce board space and improve signal quality on octal buses. It is suitable for applications needing direct TTL level compatibility and overvoltage tolerance. Consider the TSSOP20 package dimensions for PCB layout constraints. Verify that the 12 mA output drive capability meets the load requirements of the destination circuitry.

Part Context

This part belongs to the 74LVT family of low-voltage CMOS logic devices manufactured by Nexperia. It is functionally equivalent to the 74LVTH2245 series. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package (SOT360-1). It serves as a high-speed transceiver solution for mixed-voltage system architectures.

Replacement Considerations

The 74LVTH2245PW is a confirmed substitute part number listed in the ordering information.
