74LVT162244BDGG,51

Overview

The Nexperia 74LVT162244BDGG,51 is a 3.3 V 16-bit buffer/driver with 3-state outputs housed in a 48-TSSOP package. It features four output enables and includes series resistance of 30 Ω per output to eliminate external termination resistors. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports BiCMOS high-speed performance. It provides an output capability of +12 mA/-12 mA and accepts overvoltage tolerant inputs up to 5.5 V.

Feature Summary

• Integrated 30 Ω series output resistance eliminates the need for external termination resistors.
• Bus-hold data inputs maintain valid logic levels for unused pins without requiring external pull-up resistors.
• IOFF circuitry ensures partial power-down mode operation by disabling outputs to prevent damaging backflow current.

Applications

• High-speed 16-bit bus interface systems
• Direct interfacing with TTL level circuits
• Live insertion or extraction applications

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm that the TSSOP48 (SOT362-1) package dimensions align with the target PCB footprint. Ensure the component meets the -40 °C to +85 °C ambient temperature operating range required for the final assembly environment.

Selection Notes

Select this component when designing 3.3 V logic systems requiring integrated termination to reduce board space. The 30 Ω internal resistance simplifies signal integrity management compared to standard buffers. Verify compatibility with 5.5 V tolerant input signals if interfacing with higher voltage buses.

Part Context

This part belongs to the 74LVT162244B family of 3.3 V logic devices manufactured by Nexperia. It utilizes BiCMOS technology to achieve high speed and strong output drive capabilities. The device is designed for general-purpose digital buffering and line driving tasks in low-voltage electronic equipment.

Replacement Considerations

Check for 74LVT162244 variants with different package options such as SSOP48 if leaded packages are preferred. Verify functional equivalence regarding the 30 Ω internal termination and bus-hold features before substituting with other 16-bit buffer ICs.
