74LVCH162245ADGG,1

Overview

The Nexperia 74LVCH162245ADGG,1 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 supports an input voltage up to 5.5 V. The device features integrated 30 Ω series termination resistors and Schmitt-trigger inputs for noise tolerance. It includes IOFF circuitry for partial power-down protection and bus hold functionality on data inputs. The component provides two independent 8-bit channels with separate direction and output enable controls.

Feature Summary

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

Applications

• Mixed 3.3 V and 5 V system translation
• High-speed data bus buffering
• Partial power-down mode applications

Procurement Notes

Verify the specific ordering suffix matches the required temperature range and package variant. Confirm that the LVCH designation is selected over LVC if bus hold functionality is required. Ensure the TSSOP48 package type aligns with the PCB footprint design. Cross-reference the manufacturer part number against official Nexperia documentation to validate authenticity.

Selection Notes

Select this component when 16-bit bidirectional data transfer is required with integrated termination. The LVCH variant is necessary if bus hold features are needed to stabilize unused inputs. Verify that the 5.5 V input tolerance meets the source driver specifications. Ensure the operating temperature range covers the intended environmental conditions.

Part Context

This device belongs to the Nexperia 74LVC/LVCH162245A family of 16-bit transceivers. It shares functional similarities with the 74LVC162245A but adds bus hold capabilities. The ADGG suffix specifically denotes the TSSOP48 plastic thin shrink small outline package. It is designed for low power consumption and high-speed operation in mixed-voltage environments.

Replacement Considerations

The 74LVC162245ADGG:11 is a compatible alternative within the same family. Verify that the LVC variant meets application requirements if bus hold functionality is not strictly necessary. Check pinout compatibility and electrical specifications before substitution.
