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 and supports inputs up to 5.5 V. The device contains four independent output enables (1OE, 2OE, 3OE, 4OE) controlling 4-bit groups. It includes Schmitt-trigger action on all inputs and bus hold circuitry for data inputs. The component is housed in a TSSOP48 package (SOT362-1) with a maximum operating temperature of +125 °C.

Feature Summary

• Integrated 30 Ohm series termination resistors for signal integrity
• Bus hold functionality on data inputs eliminates external pull-up requirements
• IOFF circuitry prevents backflow current during partial power-down states
• Schmitt-trigger inputs provide tolerance for slow rise and fall times

Applications

• Mixed 3.3 V and 5 V logic environments
• Multibyte flow-through standard pin-out architectures
• Partial power-down applications requiring backflow protection

Selection Notes

Select this variant when internal termination resistors are required to minimize reflections without external components. The LVCH family offers lower power consumption compared to standard LVC variants while maintaining 5 V tolerance. Ensure the design utilizes the dedicated ground and power pins to leverage the low inductance architecture for noise reduction.

Part Context

This component belongs to the 74LVCH162244A family, which shares the same logical function as the 74LVC162244A but features optimized CMOS technology for reduced power dissipation. Both variants utilize the same multibyte flow-through architecture and pinout, allowing for direct functional compatibility in designs where power efficiency is prioritized over the standard LVC specifications.

Replacement Considerations

The 74LVC162244ADGG,1 serves as the non-LVCH equivalent within the same package. Verify that the application can accommodate the slightly higher power consumption of the standard LVC variant if replacing the LVCH version.
