74LVT162244BDGG:51

Overview

The 74LVT162244BDGG:51 is a 3.3V 16-bit buffer and line driver manufactured by Nexperia, formerly NXP Standard Products. It features non-inverting 3-State outputs with integrated 30Ω series termination resistors in both high and low states to reduce line noise. The device operates within a supply voltage range of 2.7V to 3.6V and supports TTL input/output switching levels. It provides bus-hold data inputs to eliminate external pull-up requirements for unused pins. The component is available in a 48-pin TSSOP package (SOT362-1) and is designed for applications such as memory address drivers, clock drivers, and bus receivers.

Feature Summary

• Integrated 30Ω series output resistance reduces line noise without external terminating components
• Bus-hold data inputs maintain logic state for unused pins, removing the need for external pull-up resistors
• Power-up 3-State functionality ensures safe initialization during power transitions
• Compatible with 5V systems through input and output interface capabilities

Applications

• Memory address drivers
• Clock drivers
• Bus receivers and transmitters

Procurement Notes

Verify that the ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the manufacturer designation reflects the current Nexperia branding rather than legacy NXP or Philips references. Ensure the specific variant aligns with the intended temperature range and packaging configuration for your design requirements.

Selection Notes

Select this component when designing 3.3V logic interfaces requiring built-in termination to minimize signal reflections. It is suitable for replacing standard buffers where external termination resistors are undesirable. Consider the 30Ω internal resistance for impedance matching in high-speed digital buses. Verify compatibility with 5V tolerant system environments if interfacing with older logic families.

Part Context

This device belongs to the LVT logic family, characterized by BiCMOS technology optimized for 3.3V operation. It is functionally equivalent to the 74LVT16244B-1, with the naming change reflecting industry standards. The product specification supersedes earlier data from Philips Semiconductors and NXP, now managed under Nexperia's portfolio of discrete, logic, and power MOS semiconductors.

Replacement Considerations

The datasheet explicitly identifies the 74LVT16244B-1 as the same part number, changed only to reflect industry standards. No other substitute part numbers are documented in the provided source material.
