74LVCH162244ADGG:1

Overview

The Nexperia 74LVCH162244ADGG:1 is a 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 1.2 V to 3.6 V, with inputs tolerant up to 5.5 V. The device supports four independent output enables (1OE through 4OE) and includes bus hold circuitry on all data inputs. It complies with JEDEC standards for low-voltage operation and provides Schmitt-trigger action at all inputs.

Feature Summary

• Integrated 30 Ohm series termination resistors for signal integrity
• Bus hold functionality on all data inputs eliminates external pull-up requirements
• IOFF circuitry prevents damaging backflow current during partial power-down
• Overvoltage tolerant inputs allow direct interfacing with 5 V devices

Applications

• Mixed 3.3 V and 5 V logic environments
• Partial power-down applications requiring IOFF protection
• High-speed digital buffering and line driving

Procurement Notes

Verify the specific ordering suffix ':1' against official Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Ensure the TSSOP-48 package variant matches the required board layout constraints. Confirm compliance with RoHS and REACH regulations relevant to the target market before finalizing procurement orders.

Selection Notes

Select this component when 16-bit buffering with integrated termination is required. The LVCH family offers lower power consumption compared to standard LVC variants. Verify that the application requires the specific bus hold feature found in the LVCH version, as the LVC counterpart lacks this function. Ensure the operating temperature range meets system requirements.

Part Context

This part belongs to the Nexperia 74LVC/LVCH 162244A family of 16-bit buffers. It shares the same pinout and core functionality as the 74LVC162244A but includes additional bus hold features. The ADGG suffix denotes the TSSOP48 plastic thin shrink small outline package. It is designed for high-density PCB layouts requiring minimal noise and ground bounce.

Replacement Considerations

The 74LVC162244ADGG is a functional equivalent without bus hold. The 74LVCH162244ADGV is an alternative package option (TVSOP48). Verify pin compatibility and electrical characteristics before substituting.
