74LVT162244BDGG,11

Overview

The Nexperia 74LVT162244BDGG,11 is a 3.3 V 16-bit buffer and line driver featuring integrated 30 Ohm series termination resistors and 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and supports direct interface with TTL levels. The device provides an output capability of +12 mA/-12 mA and includes bus-hold data inputs to eliminate external pull-up requirements. It utilizes BiCMOS technology for high-speed performance and features IOFF circuitry for partial power-down mode operation.

Feature Summary

• Integrated 30 Ohm series termination resistors on outputs remove the need for external components.
• Bus-hold data inputs maintain unused input states without requiring external pull-up resistors.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent backflow current.
• Overvoltage tolerant inputs allow safe interfacing with signals up to 5.5 V.

Applications

• High-speed 16-bit bus interfaces
• Buffering applications requiring live insertion or extraction
• Systems utilizing mixed voltage domains with overvoltage tolerant inputs

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the necessary JEDEC standards for your application environment. Ensure that the operating temperature range aligns with your system specifications. Check for any recent product change notices that may affect pinning or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when designing 3.3 V systems requiring 16-bit buffering with built-in termination. It is suitable for applications needing direct TTL level interfacing and overvoltage tolerance. Consider its BiCMOS technology for speed requirements and verify that the TSSOP48 package fits your PCB layout constraints. Ensure compatibility with the specified 2.7 V to 3.6 V supply voltage range.

Part Context

This part belongs to the 74LVT logic family, designed for low-voltage CMOS applications. It is manufactured by Nexperia USA Inc. and is housed in a TSSOP48 plastic thin shrink small outline package (SOT362-1). The device is specified for industrial temperature ranges and complies with relevant JEDEC standards for ESD protection and latch-up performance.

Replacement Considerations

Check for exact pin-to-pin compatible alternatives within the same logic family. Verify that substitute parts offer similar termination resistance values and output drive capabilities. Ensure that replacement components support the same voltage ranges and functional features like bus-hold inputs.
