74LVT2245DB,112

Overview

The Nexperia 74LVT2245DB,112 is an octal bidirectional 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 and utilizes BiCMOS technology for high-speed performance. The device includes bus hold data inputs to eliminate external pull-up requirements and supports live insertion and extraction. It provides overvoltage tolerant inputs up to 5.5 V and incorporates IOFF circuitry for partial power-down mode operation.

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 V logic
• IOFF circuitry enabling partial power-down mode operation

Applications

• Octal bidirectional bus interfaces
• Systems requiring live insertion and extraction
• Mixed 5 V and 3.3 V logic applications

Procurement Notes

Verify the package type matches the design requirement, as the DB suffix indicates an SO20 plastic small outline package (SOT163-1). Confirm that the operating temperature range of -40 °C to +85 °C aligns with the application environment. Ensure input voltages do not exceed the absolute maximum ratings to prevent damage.

Selection Notes

Select this component when designing systems that require integrated termination resistors to reduce external component count. It is suitable for applications needing bi-directional data transfer between 3.3 V buses with tolerance for 5 V signals. Consider the SO20 package dimensions and thermal characteristics during PCB layout planning.
