74LVC162244ADGG:11

Overview

The Nexperia 74LVC162244ADGG:11 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 driven by 3.3 V or 5 V devices, enabling use as a translator in mixed-voltage environments. The device includes Schmitt-trigger action for noise immunity and IOFF circuitry for partial power-down protection. It is housed in a 48-lead TSSOP package (SOT362-1) with an operating temperature range of -40 °C to +125 °C.

Feature Summary

• Integrates 30 Ohm series termination resistors on all data lines to minimize signal reflections.
• Features four independent output enable controls (1OE, 2OE, 3OE, 4OE) managing 3-state outputs.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow current during power-down.
• Provides Schmitt-trigger input action to tolerate slower input rise and fall times.

Applications

• Mixed 3.3 V and 5 V logic level translation
• Parallel bus buffering and line driving
• Partial power-down system configurations

Procurement Notes

Verify the specific suffix :11 corresponds to the required tape-and-reel packaging configuration. Confirm the DGG variant matches the SOT362-1 TSSOP48 package dimensions. Ensure the design accounts for the 30 Ohm internal termination resistors when calculating external impedance matching requirements.

Selection Notes

Select this component for applications requiring high-density 16-bit buffering with built-in termination. The LVC family offers low power consumption while maintaining compatibility with standard logic levels. Consider the TVSOP48 variant if a narrower body width is necessary for PCB layout constraints.

Part Context

This part belongs to the 74LVC162244A family of 16-bit buffers. It shares functional similarities with the 74LVCH162244A but lacks the bus hold feature found in the LVCH version. Both variants utilize the same pinout and electrical characteristics regarding drive strength and voltage tolerance.

Replacement Considerations

The 74LVCH162244ADGG:11 is a direct functional substitute, differing primarily by the inclusion of bus hold circuits on data inputs. Other 16-bit buffers from the 74LVC family may require external termination resistors and lack the specific pinout compatibility.
