74LVT2245DB,118

Overview

The Nexperia 74LVT2245DB,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 using BiCMOS technology. The device provides an output drive capability of +12 mA and -12 mA with TTL input and output switching levels. It includes overvoltage tolerant inputs up to 5.5 V and bus hold data inputs to eliminate external pull-up requirements. The component is housed in an SO20 (SOT163-1) package and supports operation from -40 °C to +85 °C.

Feature Summary

• Integrated 30 Ω output termination resistors for signal integrity
• Bus hold data inputs to maintain unused input states without external components
• IOFF circuitry enabling partial power-down mode operation
• Overvoltage tolerant inputs allowing direct interface with 5 V buses

Applications

• Octal bidirectional bus interfaces
• Systems requiring live insertion and extraction
• Mixed voltage environments connecting 3.3 V logic to 5 V buses

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the revision history status to ensure the document reflects the latest manufacturing specifications. Check compliance documentation for RoHS and REACH requirements relevant to your region. Ensure the intended operating temperature range aligns with the specified -40 °C to +85 °C limits for reliable performance.

Selection Notes

Select this component when designing systems that require integrated termination resistors to reduce board space and improve signal quality at 3.3 V. It is suitable for applications needing high noise immunity and protection against overvoltage conditions on input lines. Consider the BiCMOS technology for its balance of speed and drive strength compared to standard CMOS alternatives.

Part Context

This device belongs to the 74LVT/LVTH series of octal bus transceivers manufactured by Nexperia. It shares functional similarities with the 74LVTH2245 but is specifically designated for LVT logic levels. The 'D' suffix indicates the SO20 plastic small outline package variant, distinguishing it from TSSOP or SSOP versions within the same logical family.

Replacement Considerations

The datasheet explicitly lists the 74LVTH2245D as a related type number within the same product family sharing identical electrical characteristics and pinout configurations.
