74LVT162244BDGG:11

Overview

The Nexperia 74LVT162244BDGG:11 is a 3.3 V 16-bit buffer/driver with 3-state outputs, housed in a TSSOP48 (SOT362-1) package. It operates within a supply voltage range of 2.7 V to 3.6 V and supports input voltages up to 5.5 V. The device features integrated series output resistors of 30 Ω, eliminating the need for external termination components. It provides an output capability of +12 mA/-12 mA and includes bus-hold data inputs to define unused pins without external pull-up resistors.

Feature Summary

• Integrated 30 Ω series output resistors remove the requirement for external termination components.
• Bus-hold data inputs maintain defined logic states for unused pins, negating the need for external pull-up resistors.
• IOFF circuitry enables partial power-down mode operation by disabling outputs to prevent backflow current.
• Overvoltage tolerant inputs allow direct interfacing with 5.5 V signals while operating at lower supply voltages.

Applications

• High-speed 16-bit bus interface systems
• Mixed voltage environments requiring 3.3 V to 5.5 V level translation
• Live insertion and extraction applications

Procurement Notes

Verify the specific ordering suffix :11 corresponds to the required tape-and-reel packaging configuration. Confirm that the TSSOP48 package variant matches your PCB footprint requirements. Ensure design compliance with the specified -40 °C to +85 °C ambient temperature operating range. Validate that the 30 Ω internal termination aligns with your transmission line impedance matching strategy.

Selection Notes

Select this component when designing 16-bit wide data buses requiring integrated termination to reduce board space and component count. It is suitable for applications needing direct interfacing between 3.3 V logic and 5.5 V tolerant buses. Consider the BiCMOS technology for high-speed performance and robust output drive capabilities in standard 3.3 V logic environments.

Part Context

This part belongs to the 74LVT family of low-voltage TTL-compatible logic devices manufactured by Nexperia. The LVT series is designed for 3.3 V applications while maintaining compatibility with 5 V tolerant inputs. The 74LVT162244B variant specifically integrates termination resistors, distinguishing it from standard buffers that require external components for signal integrity management.

Replacement Considerations

Direct substitutes include other 74LVT162244 variants such as the 74LVT162244DL or 74LVT162244PW, provided they offer identical pinouts and electrical characteristics. Verify package compatibility when swapping between TSSOP48, SSOP48, or other available footprints.
