74LVT162240ADGG,51

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74LVT162240ADGG,51 is a high-performance BiCMOS inverting buffer/driver designed for VCC operation at 3.3 V (range 2.7 V to 3.6 V). It features 16-bit bus interface capability with four independent output enable pins controlling three-state outputs. The device incorporates internal series resistance of approximately 30 Ω in both pull-up and pull-down structures to reduce line noise without external termination resistors. It supports TTL input/output switching levels and interfaces with systems at 5 V supply. Operating temperature range is -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix ',51' against official Nexperia documentation to confirm package type and reel specifications. Ensure the application environment remains within the specified -40 °C to +85 °C operating temperature range. Confirm that the 3.3 V supply voltage aligns with the recommended operating conditions for optimal performance and signal integrity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed inverting buffering with integrated termination capabilities. The BiCMOS technology provides robust drive strength suitable for driving bus lines. Consider the four independent output enables for flexible control of different bus segments. Verify compatibility with 5 V systems due to its interface capability and TTL switching levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVT logic family, which utilizes Advanced Low-Voltage BiCMOS Technology. It is specifically engineered for 3.3 V systems but offers compatibility with 5 V buses. The TSSOP48 package (SOT362-1) provides a compact solution for dense PCB layouts. It serves as a specialized buffer for high-speed digital interfaces where signal integrity and noise reduction are critical.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consult official Nexperia substitution guides for verified equivalents. Generic 16-bit buffers may lack the integrated 30 Ω termination or bus-hold features. Ensure any replacement maintains the same 3-state functionality and voltage compatibility.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

The device features bus-hold data inputs that automatically hold unused inputs at a defined logic level, eliminating the need for external pull-up resistors.

What is the purpose of the internal series resistance?

The internal 30 Ω series resistance in the output structures reduces line noise and ringing, making external termination resistors unnecessary for many applications.

Can this device be used in hot-swap applications?

Yes, the device permits live insertion and extraction and prevents bus current loading when the output is tied to a 5 V bus.
