74LVT2245D,118

Overview

The Nexperia 74LVT2245D,118 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 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. Propagation delays are typically 3.2 ns at 3.3 V. The component is housed in a SOIC-20 (SOT163-1) package.

Feature Summary

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

Applications

• Octal bidirectional bus interface systems
• Mixed 5 V and 3.3 V application environments
• High-speed memory bus implementations

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the D suffix corresponds to the SOIC-20 plastic small outline package. Ensure the temperature range specification aligns with operational requirements. Check for any recent product change notifications regarding manufacturing site or material updates before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated source termination to reduce external component count. The device is suitable for applications needing direct interface with TTL levels while operating at 3.3 V. Consider the BiCMOS technology benefits for high-speed data transmission. Verify compatibility with system voltage domains given the 5.5 V input tolerance.

Part Context

This part belongs to the 74LVT/LVTH logic family, designed for low-voltage applications. It serves as an octal transceiver variant within the broader 74-series logic portfolio. The device complements other bus transceivers by adding internal termination features. It is manufactured using BiCMOS processes to balance speed and drive capability.

Replacement Considerations

Direct pin-compatible alternatives include the 74LVTH2245D,118 variant which shares identical electrical characteristics and functionality. Other octal transceivers from the same manufacturer may require external termination resistors.
