74LVC16245ADGG,112

Overview

The Nexperia 74LVC16245ADGG,112 is a 16-bit bus transceiver with direction pins and 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device supports mixed 3.3 V and 5 V environments and includes Schmitt-trigger action at all inputs. It utilizes the TSSOP48 (SOT362-1) package with a body width of 6.1 mm. The component is specified for ambient temperatures ranging from -40 °C to +125 °C.

Feature Summary

• Provides partial power-down protection via IOFF circuitry to prevent damaging backflow currents when powered down.
• Includes bus hold functionality on data inputs to eliminate the need for external pull-up resistors for unused inputs.
• Features low inductance multiple power and ground pins designed to minimize noise and ground bounce.

Applications

• Mixed 3.3 V and 5 V translation environments
• Partial power-down applications requiring IOFF support
• Systems utilizing TTL level direct interfaces

Procurement Notes

Verify that the ordering suffix matches the required package variant. Confirm the specific temperature grade aligns with system requirements. Ensure compatibility with the intended supply voltage range before procurement. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and current production status.

Selection Notes

Select this component for designs requiring 16-bit bidirectional data transfer with independent direction control. The LVCH variant provides bus hold features absent in standard LVC versions. Verify input voltage tolerance levels match the source logic family. Consider the thermal derating characteristics for high-density surface mount layouts.

Part Context

This device belongs to the 74LVC/LVCH family of CMOS logic integrated circuits manufactured by Nexperia. It functions as a high-speed bus transceiver suitable for general-purpose digital systems. The ADGG suffix specifically denotes the TSSOP48 plastic thin shrink small outline package configuration.

Replacement Considerations

The 74LVCH16245ADGV serves as a pin-compatible alternative housed in the TVSOP48 package. Both variants share identical electrical specifications and functional behavior.
