74LVCH162244ADGG:5

Overview

The 74LVCH162244ADGG:5 is a 16-bit non-inverting buffer and line driver featuring 3-state bus-compatible outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs up to 5.5 V, enabling mixed-voltage interfacing. The device integrates four output enable inputs (nOE) for independent control of output states. It includes 30 Ω series termination resistors in both high and low output stages to minimize line noise. All data inputs feature bus hold functionality to maintain logic levels without external pull-up resistors.

Feature Summary

• Integrates 30 Ω series termination resistors in output stages to reduce signal reflections and line noise.
• Provides bus hold circuitry on all data inputs to eliminate the need for external pull-up resistors.
• Features 5 V tolerant inputs and outputs, allowing direct interface with 5 V logic devices.
• Offers four independent output enable inputs to control 3-state outputs individually.

Applications

• Mixed 3.3 V and 5 V system interconnects
• High-speed data buffering applications
• Line driving for communication buses

Procurement Notes

Verify that the specific ordering suffix matches the required package variant and temperature rating. Confirm compliance with current JEDEC standards for the intended operating voltage range. Ensure the component meets RoHS directives relevant to the manufacturing region. Cross-reference the manufacturer's latest datasheet revision to validate electrical characteristics against design requirements.

Selection Notes

Select this component when designing systems requiring 16-bit buffering with integrated termination to improve signal integrity. It is suitable for applications needing 5 V tolerance to bridge different logic families. Consider the TSSOP48 package constraints regarding board space and thermal dissipation. Verify that the four separate output enables align with the system's control architecture.

Part Context

This part belongs to the 74LVC/LVCH family of CMOS logic devices manufactured by Nexperia, formerly NXP Semiconductors. The LVCH designation indicates Low Voltage CMOS technology with 5 V tolerance. The 162244A suffix identifies it as a 16-bit buffer/line driver with 3-state outputs. The ADGG suffix specifies the TSSOP48 plastic thin shrink small outline package.

Replacement Considerations

The 74LVC162244ADGG is a compatible alternative within the same family but lacks the bus hold feature found in the LVCH version. Other variants such as the SSOP48 package versions may be considered if pin compatibility allows.
