74LVC162245ADGG:11

Overview

The Nexperia 74LVC162245ADGG:11 is a 16-bit bus transceiver housed in a TSSOP48 (SOT362-1) package. It operates within a supply voltage range of 1.2 V to 3.6 V and features 3-state outputs with integrated 30 Ω series termination resistors. The device supports two independent 8-bit channels, each controlled by separate output enable (OE) and direction (DIR) inputs. Inputs are overvoltage tolerant up to 5.5 V, allowing direct interfacing with 3.3 V or 5 V logic devices. Schmitt-trigger action ensures tolerance for slow input transitions.

Feature Summary

• Integrated 30 Ohm series termination resistors on data lines
• IOFF circuitry prevents damaging backflow current during partial power-down
• Overvoltage tolerant inputs compatible with 5.5 V signals

Applications

• Mixed 3.3 V and 5 V environment translation
• Partial power-down applications requiring IOFF functionality
• High-speed multibyte flow-through data buses

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the :11 designation corresponds to the TSSOP48 plastic thin shrink small outline package. Ensure compatibility with the -40 °C to +125 °C temperature range specified for this part number before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer with integrated impedance matching. The presence of IOFF circuitry makes it suitable for applications where parts of the system may be powered down while others remain active. Verify that the 30 Ω termination resistors align with the transmission line requirements of the target application.

Part Context

This device belongs to the 74LVC/LVCH family of high-speed CMOS logic. It serves as a level-shifting interface between low-voltage logic cores and higher-voltage peripheral buses. The ADGG suffix specifically identifies the TSSOP48 package configuration, distinguishing it from other physical form factors like TVSOP48 available within the same logical family.

Replacement Considerations

The 74LVCH162245ADGG is a functional equivalent within the same product family.
