74LVC16245AEV/G,51

Overview

The Nexperia 74LVC16245AEV/G,51 is a 16-bit bus transceiver with 3-state outputs. It supports a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes IOFF circuitry for partial power-down mode operation. It operates within an ambient temperature range of -40 °C to +125 °C.

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 damaging backflow current.
• Schmitt-trigger action at all inputs provides tolerance for slower input rise and fall times.

Applications

• Mixed 3.3 V and 5 V environment translation
• Partial power-down applications
• Bidirectional data bus transmission

Procurement Notes

Verify the specific package type against the datasheet, as the EV suffix indicates a VFBGA-56 package which differs from the TSSOP48 or TVSOP48 packages detailed in the standard product data sheet. Confirm availability status directly with Nexperia or authorized distributors, as this specific part number may be subject to production changes or obsolescence notices.

Selection Notes

Select this component when a 16-bit bidirectional interface is required with 5 V tolerance on a lower voltage supply rail. Ensure the design accommodates the VFBGA-56 package constraints if using the AEV variant. Verify that the application does not require the bus hold feature, which is specified only for the LVCH series variants.

Part Context

This device belongs to the 74LVC family of logic ICs, designed for low-voltage CMOS applications. It functions as a high-speed bus transceiver capable of operating as two independent 8-bit transceivers or one 16-bit transceiver. The LVC series is characterized by wide supply voltage compatibility and low power dissipation.

Replacement Considerations

The 74LVCH16245A is a related variant within the same family that includes bus hold functionality on data inputs. Designers should verify pinout compatibility and functional differences, particularly regarding the absence of bus hold in the standard LVC version.
