74LVC16245AEV/G,55

Overview

The Nexperia 74LVC16245AEV/G,55 is a 16-bit bus transceiver with 3-state outputs. It supports two 8-bit or one 16-bit configuration using dual output enables and direction controls. The device features overvoltage tolerant inputs up to 5.5 V and operates on a supply voltage range of 1.2 V to 3.6 V. It includes IOFF circuitry for partial power-down applications to prevent backflow current. Schmitt-trigger inputs ensure tolerance to slow signal transitions.

Feature Summary

• Overvoltage tolerant inputs allow direct interfacing with 5 V devices in mixed voltage environments.
• IOFF circuitry disables outputs during power-down to prevent potentially damaging backflow currents.
• Schmitt-trigger action at all inputs provides noise immunity and tolerance for slower rise and fall times.

Applications

• Mixed 3.3 V and 5 V voltage translation
• Partial power-down system configurations
• High-noise environment data transmission

Procurement Notes

Verify the specific suffix /G,55 against official Nexperia documentation to confirm package type and tape/reel specifications. Confirm availability status as distribution channels may list obsolete or discontinued variants. Ensure design compliance with JEDEC standards relevant to the target operating voltage range before procurement.

Selection Notes

Select this component when bidirectional level shifting between 1.2 V and 3.6 V domains is required with 5 V input tolerance. The dual enable pins allow independent control of two 8-bit sections. Verify that the application does not require the bus hold feature, which is exclusive to the LVCH variant.

Part Context

This part belongs to the 74LVC family of low-voltage CMOS logic devices. It functions as a standard pin-out architecture transceiver compatible with MULTIBYTE flow-through designs. The device is designed for high-speed data transfer with low power dissipation characteristics typical of modern LVC technology.

Replacement Considerations

The 74LVCH16245A is a related variant within the same datasheet that includes bus hold functionality on data inputs. Designers requiring input holding capabilities should consider the LVCH version instead of the standard LVC version.
